Ledger Live Mac App: Local Signing and Staking Routes


Ledger Live Mac App: How Signing Works and Which Details Leave Your Computer

This is a standalone HTML document that presents a practical guide to setting up and using the Ledger Live Mac app. It combines structured reference content with verification steps, comparison tables, and schema markup for clarity.

Research Notice: This walkthrough is independent documentation drawn from publicly published vendor material and is not affiliated with the hardware wallet maker. Verify every download location, version number, fee, validator list, or regional restriction on the official source before acting, because those details are revised without notice.

Ledger Live Mac App Setup and Usage Guide starts from one rule: obtain the desktop client only from the maker’s own download page, never from a search result, a mirror, or a chat link. The sections below explain what the program does on your machine, which jobs it suits, how it differs from the phone build or a third-party interface, where people lose funds, how to verify a download, plus which details shift between releases.

How the desktop companion works: local signing, remote chain data

The desktop client holds no private keys. It builds a transfer on your computer, sends it to the hardware wallet for approval, then broadcasts the signed result through the maker’s node infrastructure. Account balances, price charts, staking positions, plus transfer history arrive from remote servers, so the program needs a live connection; the device alone confirms what you authorise.

Where the signing key stays during a transfer

The private key never leaves the hardware wallet. The desktop program only assembles an unsigned payload describing the recipient, the amount, the network fee, plus any chain-specific field such as a memo or a nonce. That payload travels down the cable to the device, which renders the destination plus the value on its own display. Approving signs the payload inside the secure element. A compromised computer can therefore propose a fraudulent transfer, but it cannot complete one without a physical button press on the trusted screen.

Which details leave your computer

Balances, token prices, staking positions, transfer histories, plus the list of accounts you added come from the maker’s servers rather than from your own copy of each chain. Public addresses therefore reach an external service, which links them to one installation. Some networks accept a custom node endpoint, letting you point the client at infrastructure you control; others do not. The practical trade-off is address-level privacy against the convenience of not maintaining full nodes for a dozen networks.

What the device display proves that the window cannot

The device display is the one screen a compromised host cannot rewrite. Address-poisoning campaigns depend on the desktop showing a familiar-looking string while the device shows the real destination, so compare the leading characters plus the trailing characters on both screens before approving. A broadcast transfer is irreversible, which is why a small test amount sent to yourself first remains the cheapest diagnostic available. If the two screens disagree on a single character, cancel the operation entirely.

Who actually needs the desktop client, for which jobs?

The desktop build suits holders of several networks who stake, manage token collections, or move larger amounts from a desk with a full keyboard. Anyone signing twice a year with a single account rarely needs it. Occasional signers can pair the same device with a chain-native web tool instead, accepting that features, fees, plus support differ by network.

One window over a dozen networks

Adding accounts for Bitcoin, Ethereum, Solana, plus the token standards layered on top of them puts every balance in one window, which matters when a single seed controls addresses on a dozen networks. That aggregation is assembled server-side, so its accuracy depends on the maker’s indexers tracking each chain’s tip. Networks the maker has not indexed never appear, regardless of what the device can sign, which is a common source of “my coins vanished” reports. The remedy is a block explorer search for the address, not a reinstall.

Staking plus built-in swap routes

Staking flows exist inside the client for the networks the maker supports; the deposit address points at a validator drawn from a published list, plus the unbonding period is fixed by the protocol rather than the software. Swap quotes route through outside providers, so the rate on screen belongs to them. Both actions still need device confirmation. Validator sets, commission rates, plus provider lists change without notice, so treat every number in that panel as published on the official source.

Jobs the software cannot do at all

No release recovers a lost recovery phrase, reverses a broadcast transfer, or signs for a network whose integration the maker has not published. It also refuses some message-signing requests that chain-native tools accept, which matters for governance votes plus off-chain attestations. When an action is missing from the interface, the answer is usually a different signing tool paired to the same device, never a second installation or an imported phrase.

Desktop build versus mobile build, browser extension, or device-native screens

Four routes can sign a transfer with the same hardware wallet: the desktop client, the phone build, a third-party browser extension, or a chain-native web page paired to the device. They differ in how much code you trust, which networks they reach, how the recipient address is checked, plus how much of the workflow depends on a live internet connection.

The table weighs five options on three criteria that decide outcomes: where the signing logic originates, which networks the tool can reach, plus how a recipient address is confirmed before the device approves it. Installation effort plus update practice follow from those three.

Signing routes for one hardware wallet, compared by code origin, reach, plus recipient checks
Route Signing code origin Networks reachable Recipient check
Maker’s desktop client Published by the device maker Networks the maker indexes; list on the official source Compare device screen against the desktop window
Maker’s phone build Same maker, separate release channel Same index, with per-network gaps Compare device screen against the handset
Third-party browser extension Independent team, browser store distribution Whatever that team integrates; published on its own site Compare device screen against the extension window
Third-party desktop wallet Independent team, self-hosted downloads Network set chosen by that team Compare device screen against the wallet window
Chain-native web tool Network’s own developers, served from their site One network plus its tokens Device screen is the only reference

Choose the maker’s desktop build when you hold several networks plus want one updater to track. Choose the phone release when you sign on the move plus accept a wireless link. Third-party options fit when you need a feature the maker never shipped, or a network it never indexed; they do not fit if you cannot establish who publishes the code. Chain-native tools fit single-network tasks. Exceptions appear where a network’s own foundation ships the only maintained interface.

Trust models when the signing code is not the maker’s

An extension or third-party desktop wallet still hands final approval to the device, so key material stays protected, but it constructs the payload you are about to sign. A malicious or buggy build can propose a different recipient, an inflated fee, or an unlimited token allowance that the device will happily display. The defence is not brand loyalty; it is reading the device screen field by field plus revoking allowances you no longer use through a block explorer.

Reach limits for networks the maker never indexed

Reach is set by the maker’s integrations, not by what the hardware can technically sign. A network absent from the companion program can still be used through that network’s own tool, and the resulting balance will not appear in the portfolio view. This gap explains most “unsupported chain” confusion: the device supports far more networks than the software chooses to display, plus integrations get added or dropped between releases.

Risks, limits, frequent mistakes that cost people funds

Most losses trace to four human steps: installing a counterfeit build, typing a recovery phrase into a keyboard, approving without reading the device display, plus ignoring lookalike addresses planted in transfer history. The program cannot move value without a physical confirmation, so an incident almost always means a step was taken under time pressure or from an unverified source.

Counterfeit installers distributed through search advertisements

Search results, video descriptions, plus direct messages routinely point at domains that mimic the maker’s site with one altered character, hosting an installer that carries the correct name, icon, plus version string. The substituted build usually asks for the recovery phrase at first launch, which the genuine client never does. The check that defeats it is an address typed by hand, plus a digest or signature comparison against the published value. Anything downloaded from a link you did not type is untrusted until that comparison passes.

Recovery phrases typed into any keyboard

No legitimate tool, support agent, or recovery service ever needs the twelve or twenty-four recovery words, because the device signs without them. Any page, chat, spreadsheet, or photograph that asks for the phrase is theft in progress. The phrase belongs on paper or metal, stored offline; typing it into a computer, a phone, or a password manager converts a hardware-wallet configuration into a hot wallet with extra steps. If the words were entered anywhere digital, move the funds to a newly generated phrase.

Blind approvals plus planted lookalike addresses

Token approvals on contract networks can grant unlimited spending rights to a contract that later turns hostile; the device screen shows the allowance granted, plus that line is worth reading. Address poisoning plants a lookalike address in your history so a copied entry sends funds straight to an attacker. Both are defeated by checking the device display, revoking stale allowances from a block explorer, plus sending a small test amount to any new destination before the main transfer.

How do you verify the installer before entering a recovery phrase?

Verification means confirming the file came from the maker, matches a published digest or signature, plus can update itself from inside the program. Have ready the maker’s download page, the published hash list, a terminal window, plus the hardware wallet itself. Nothing in this procedure requires a recovery phrase.

Step 1: Type the official domain by hand

Type the maker’s domain into the address bar by hand rather than following a link from a message, an advertisement, or a video description. A manually entered address sidesteps typosquatted domains that serve a modified installer carrying the same icon plus name.

Step 2: Match the published digest

Compare the digest published in the maker’s documentation against the hash of your downloaded file, computed with the hashing utility built into the operating system. A matching digest proves the bytes arrived intact, though not who published them, which is why the following check matters.

Step 3: Inspect the signature attached to the package

Inspect the signing certificate or notarisation stamp attached to the installer plus confirm the identifier matches the maker named on the download page. A mismatch is grounds for deleting the file rather than experimenting with it, because a valid signature means the holder of that certificate assembled the package.

Step 4: Launch offline and compare the version

Launch the program with the hardware wallet unplugged, let it check for updates, then compare the reported version against the published release notes. This is the last checkpoint before any account or key material is in scope, so a stale version is worth resolving there rather than later.

Step 5: Pair an empty account and test

Connect the device, add one empty account, plus send a small test amount to your own address before funding anything. A test transfer exposes a wrong network or a wrong address while the mistake still costs almost nothing.

What stays unsettled: version floors, regional limits, changing requirements

Three details shift without notice: the minimum operating system a release supports, which networks plus services appear in your region, plus which device revisions still receive firmware. The maker’s compatibility notes plus release announcements carry the current values. Any figure quoted in a third-party article, including this one, is a snapshot of the day it was written.

Operating system floors keep rising

Each annual release of the client raises the oldest Apple desktop version it will run on, plus drops support for processor families the build no longer targets. An older machine can be stuck on an obsolete release that still opens but refuses to sync some networks. The published system requirements on the maker’s product page decide this, so read them before troubleshooting a client that launches then fails to connect. Keeping an old build alive is not the same as being supported.

Regional blocks on swap, buy, plus staking panels

Swap, on-ramp, plus staking panels are supplied by regulated third parties, so they appear or disappear by country rather than by software version. A feature missing from your screen usually means a licensing boundary, not a broken installation. Availability, fees, plus provider names are listed inside the panel itself plus on the official source, so check there instead of reinstalling. Virtual private networks do not resolve this, plus using one may breach the provider’s terms.

Device revisions that stop receiving firmware

Older device revisions eventually stop receiving firmware, which caps the networks plus features their companion program can drive. The client typically still recognises such a unit for signing but stops offering newer flows, so the limit looks like a software problem when it is a hardware one. The maker’s firmware release notes state which revisions are still maintained. When a transfer needs a feature the unit cannot handle, a newer unit restored from the same recovery phrase regains access to those flows.

Research Notice: This article explains source verification, compatibility checks, plus safety limits. It does not provide financial advice, investment guidance, or recovery instructions. Always confirm current details on the vendor-controlled page.

Downloading Ledger Live from the Official Ledger Website for macOS begins at the vendor-controlled page, not at a search ad or file-sharing mirror. The page publishes the current disk image name, compatibility notes, cryptographic hash, plus signing identity. Verify those details before the first launch.

What does the direct download include for Apple desktops?

The direct download delivers a signed disk image containing the desktop client for Apple computers. It includes the application bundle, support files, plus published verification data. The vendor-controlled download page also states the minimum operating system version, release number, architecture match, plus required system permissions. These components are packaged for one installation step, so the user does not assemble dependencies manually.

Disk image contents plus signing identity

A disk image bundles the client binary, resources, plus a signature that identifies the publisher. The signature is created with the vendor’s private key, so the operating system can confirm that the package was not altered after release. Opening the image reveals a single application file rather than an installer script that runs hidden commands. This design limits the places where malicious code can hide, because the signed seal covers the main executable plus its enclosed assets. If the signature is missing or attributed to an unknown developer, the package should be treated as untrusted.

Compatibility metadata tied to the operating system build

Compatibility metadata ties each release to specific operating system builds, processor architectures, plus minimum memory conditions. The vendor page lists these requirements beside the download button, so a user can compare them with the target machine before saving the file. An Apple silicon build will not run correctly on an Intel-only system if the package lacks the required translation layer. Conversely, an older operating system build may reject a newer client even when the disk image opens. Checking this metadata first prevents wasted installation attempts plus confusing launch failures.

Release notes that define version-specific behavior

Release notes define what changed in each version, which fixes were included, plus any known limits. They also state whether the package replaces an older installation or requires a clean removal first. A user who skips these notes may keep stale configuration files that conflict with new permission prompts. The notes can also flag a paused rollout, a withdrawn build, or a compatibility break for certain hardware revisions. Reading them before download avoids installing a release that the vendor has already superseded.

Who needs this installation route, when, for which devices

This route suits anyone who wants the desktop client directly from the vendor without an intermediary. It applies when a user has administrative rights, a compatible Apple computer, plus enough storage for the disk image. It also fits fresh installations, version replacements, plus recovery from a corrupted existing copy. Users on managed machines should confirm local policy before proceeding.

New desktop users with no existing client

A new desktop user needs the signed package because no prior configuration exists to migrate. The first launch will create local databases, set permission prompts, plus establish a connection method for the hardware device. Starting from the vendor page avoids preconfigured bundles that may include altered launch agents. The user should have the device, recovery phrase backup, plus operating system password ready before opening the client. These items support account configuration without exposing secrets to unknown software.

Existing users replacing an older release

An existing user replaces an older release to gain fixes, security patches, plus compatibility updates. The disk image installs over the prior application while preserving local settings, but the user should confirm that the release notes allow an in-place replacement. A clean removal may be required when the vendor changes signing identity, database format, or permission model. Backing up local configuration before replacement prevents loss if the new build rejects old data. The replacement should come from the same vendor-controlled page as the original source.

Restricted workstations with managed permissions

A restricted workstation may block unsigned packages, unknown developers, or disk images from external sources. The user needs local administrator approval before mounting the image or copying the client into the Applications directory. Some management profiles also prevent background network access, which the client needs for blockchain synchronization. In those cases, the vendor page remains the correct source, but the information technology team must allow the signed package. Without that approval, installation stops at the operating system gate.

How does this route compare with package managers, direct mirrors, third-party bundles

The vendor-controlled route differs from package managers, direct mirrors, plus third-party bundles mainly in trust anchor, version freshness, plus manual effort. It gives the user a signed artifact tied to the manufacturer’s domain. Package managers add automation but depend on maintainer updates. Mirrors can lag or disappear. Bundles add unknown repackaging risk.

The table compares four acquisition routes by four criteria: trust anchor, version freshness, installation effort, plus main limit. Trust anchor means the identity that the user must rely on before opening the package. Version freshness means how closely the route tracks the vendor’s current release. Installation effort covers steps required before first launch. Main limit is the condition that makes the route unsuitable in some environments. Values that change by release are stated as published on the official source.

Acquisition routes for the desktop client on Apple computers
Route Trust anchor Version freshness Main limit
Vendor-controlled page Domain plus published signatures Current release listed on official source Manual verification before opening
Package manager Maintainer recipe plus upstream signature Depends on maintainer update cycle Delayed or altered builds possible
Direct mirror Mirror operator identity Mirrored release may lag official source Extra domain to verify
Third-party bundle Bundle distributor reputation Repackaged from official source Unknown additions hard to audit

The vendor-controlled page fits users who accept a manual download plus a short verification step. It does not fit environments that forbid direct vendor downloads without a management approval. Package managers fit users who prefer automated updates plus accept maintainer delay. Direct mirrors fit only when a trusted internal mirror is maintained, yet they require an extra identity check. Third-party bundles fit no security-sensitive case because their added files are hard to audit; the exception is a bundle signed by the vendor itself, which should then be treated as the vendor route.

Trust anchor differences

Trust anchor differences decide which identity the user must verify before installation. The vendor-controlled page relies on the manufacturer’s domain plus a code signature, so the user can cross-check both against published details. A package manager shifts part of that trust to a maintainer recipe, which may be reviewed by a community but not by the manufacturer. A mirror adds the mirror operator as another identity, even when the underlying file is unchanged. A third-party bundle adds the distributor’s reputation plus any modifications they made. Each added identity increases the number of checks needed.

Version freshness trade-offs

Version freshness trade-offs determine how quickly a user receives fixes, security patches, plus compatibility updates. The vendor-controlled page lists the current release as soon as the manufacturer publishes it, though the user must check manually. Package managers may update only after a maintainer rebuilds plus tests the package, which can delay urgent fixes. Mirrors may lag until an operator synchronizes files, so a stale version can remain visible. Third-party bundles may repackage an older release without clear version labels. A user who needs the newest signed artifact should compare the route against the vendor’s release page.

Risks, limits, common mistakes during acquisition

Acquisition risks include lookalike domains, unverified disk images, architecture mismatches, plus skipped signature checks. The main limit is that no download route can prove safety after the user bypasses system warnings. Common mistakes are trusting search ads, opening files without comparing hashes, plus ignoring version notes. These errors can install corrupted or altered software before any wallet operation begins.

Lookalike domains that imitate the vendor

Lookalike domains imitate the vendor by using similar spelling, hyphens, or top-level extensions. A user who clicks a search ad may land on a page that copies logos, layout, plus download buttons while serving a different disk image. The browser address bar is the primary check: the registered domain must match the manufacturer’s official domain exactly. Certificate padlocks do not prove ownership because any domain can obtain one. Bookmarking the verified page reduces the chance of a typo redirect.

Unverified disk images from chat shares

Unverified disk images from chat shares, forums, or cloud drives lack a reliable chain back to the manufacturer. Even when the file name looks correct, the package may include a wrapper that modifies the launch process. The user cannot compare a hash unless the sender also provides one from the vendor page, which is rarely done. A signed package from an unknown sender can still be a legitimate copy, but the signature alone does not prove that the sender did not alter surrounding files. The safe rule is to discard the file plus obtain a fresh copy from the vendor page.

Skipping architecture mismatch checks

Skipping architecture mismatch checks causes launch failures that look like software bugs. An Apple silicon machine needs an arm64 build or a compatible translation layer; an Intel machine needs an x86_64 build. The vendor page states the intended architecture beside the download link. A user who ignores that label may install a package that opens but crashes during device connection. Checking the architecture before download saves troubleshooting time plus prevents false reports of a broken release.

How do you verify a downloaded installer before opening it?

Verify a downloaded installer by checking its origin, file details, cryptographic hash, plus code signature before opening it. Have the saved disk image, the vendor-published checksum, plus access to the system terminal ready. This procedure catches corrupted files, wrong architecture builds, plus tampered packages before they can alter the system.

Step 1: Locate the saved disk image

Open the Downloads folder, then select the disk image file that matches the current release listed on the vendor page. The exact file name confirms that the browser saved the intended package rather than a partial or renamed copy.

Step 2: Compare file name plus extension with the official listing

Read the file name, version string, plus extension against the vendor-controlled download page. A mismatch signals a stale release, a wrong architecture build, or a renamed third-party file.

Step 3: Compute the cryptographic hash with a terminal command

Run the system hash utility on the saved file to produce a long hexadecimal digest. The digest is a fixed-length fingerprint that changes if even one byte in the package is altered.

Step 4: Compare the digest with the vendor-published value

Place the computed digest next to the checksum printed on the official download page, then compare every character. Identical values show that the file matches the vendor’s published artifact for that release.

Step 5: Inspect the code signature before launch

Run the system signature-checking utility on the disk image, then review the reported developer identity plus notarization status. A valid signature tied to the vendor, plus a recorded notarization check, confirms that the package has not been modified after signing.

What commonly gets mistaken about the installer source?

Common mistake treats a search result, signed status, or automatic update as proof of installer source. The vendor-controlled page remains the only origin checked against the manufacturer’s published domain, hash, plus signature. A valid signature proves publisher identity for signed bytes, not compatibility with every system build. Automatic updates begin from a trusted installation; they cannot repair a compromised download.

Search results are not the source

Search results are not the source because ads, sponsored links, plus organic snippets can point to rehosted files. The visible domain in the address bar is the only identity that matters, not the page title or logo. A result that ranks first may be purchased placement rather than the manufacturer’s page. Even a correct-looking snippet can redirect through an affiliate tracker before reaching the final site. The user should type the known domain or use a saved bookmark instead of clicking a result.

A valid signature is not a compatibility guarantee

A valid signature is not a compatibility guarantee because it only confirms which developer signed the bytes. It does not prove that the release matches the installed operating system, processor architecture, or available memory. A correctly signed package can still fail to launch if the system build is too old. It can also open but behave unpredictably when required permissions are denied. The user must check compatibility metadata separately from the signature check.

Silent updates are not part of the download

Silent updates are not part of the initial download because the first package must be installed from a verified source. Automatic update mechanisms rely on the existing installation’s trust store plus network connections to the manufacturer. If the first installation came from an altered bundle, later updates may preserve the compromise instead of correcting it. The user should not treat an update notification as a substitute for verifying the original disk image. Reinstalling from the vendor page remains the clean recovery path when source trust is uncertain.

Q&A:

Do I have to type my 24-word recovery phrase into Ledger Live while setting it up on a Mac?

No. Ledger Live does not ask for your recovery phrase during setup, account creation, firmware updates, or any normal use. You enter your PIN only on the Ledger device itself. If you are restoring a wallet, you enter the recovery phrase on the device, not on the Mac. Any website, pop-up, or app that asks for those words is trying to steal them. Keep the phrase offline and never store it in a note, photo, password manager, or cloud drive.

Which Macs and macOS versions can run Ledger Live?

Ledger Live is built for macOS. It runs on Intel Macs and Apple silicon Macs. The exact minimum macOS version can change between releases, so check the download page on Ledger’s official site before installing. If your Mac is too old for the newest build, the installer may fail or the app may not open. In that case, use a supported Mac or an older Ledger Live release only if Ledger still offers it. For Bluetooth connections, you need a Nano X and a Mac with working Bluetooth. Nano S, Nano S Plus, and Flex use a USB cable.

How do I install apps on my Ledger device through Ledger Live on Mac?

Connect the Ledger to your Mac with a data-capable USB cable, or use Bluetooth with a Nano X. Open Ledger Live, enter your PIN on the device, and open the My Ledger section. The device will show a prompt to allow the manager; approve it on the device. Find the coin app you need, such as Bitcoin, Ethereum, or Solana, and choose Install. Keep the device connected and awake during the install. If the install fails, check that the device has enough free space, update the firmware if Ledger Live offers an update, then try another USB port or cable.

Why is my Ledger not detected by Ledger Live on macOS?

This can happen for a few reasons. First, make sure the Ledger is connected directly to the Mac, not through a hub, and use a cable that carries data. Some USB cables only charge. Second, enter your PIN on the device and open Ledger Live. Third, close other wallet apps, browser extensions, and crypto programs that may already be using the device. Fourth, check that Ledger Live is the newest version from Ledger’s official site. On newer macOS releases, check System Settings > Privacy & Security for accessory or Bluetooth permissions and allow Ledger Live if macOS asks. For a Nano X over Bluetooth, turn Bluetooth on, remove any old pairing for the device, and pair it again from Ledger Live. If the device still does not appear, restart the Mac, try a different USB port, and test the Ledger on another computer. If none of that works, contact Ledger support.

Can I use Ledger Live on my Mac without the Ledger device plugged in?

You can open Ledger Live and view accounts that are already added, check balances, and review transaction history without the device connected. You cannot send crypto, receive crypto to a new address, install or remove device apps, or update firmware without the Ledger. Those actions need you to confirm them on the hardware wallet. If you only need to watch your portfolio, the app can show the last synced data. For any move of funds, connect the device, enter your PIN, and verify every address and amount on the Ledger screen before you approve.

Should I get Ledger Live from the Mac App Store or directly from Ledger’s website?

Get it directly from Ledger’s official website (ledger.com). Ledger does not publish Ledger Live in the Mac App Store. Download the macOS version, open the .dmg, drag Ledger Live to Applications, then open it. If macOS blocks the app, go to System Settings > Privacy & Security and click Open Anyway for Ledger Live. Confirm the download page is ledger.com and check the app signature if you want extra assurance. Avoid third-party mirrors.

My Ledger Nano won’t show up in Ledger Live on my Mac. What should I try?

Try a different USB cable and a port on the Mac itself, not a hub. Enter your PIN on the device, open the Ledger Live app, and check that the device is on the dashboard. For Nano X, turn on Bluetooth on both the Mac and the device, then pair it in Ledger Live. Close other wallet apps that may use the device. If a macOS permission pop-up appears, allow Ledger Live to access the USB device. Restart Ledger Live and the Mac. If the device still does not appear, check Ledger’s support page for your model and macOS version.

How do I send and receive crypto in Ledger Live on Mac without putting my recovery phrase at risk?

Use the Accounts tab. To receive, select the account, click Receive, and let Ledger Live show an address. Check the same address on your Ledger screen before you share it. For some coins, the address may change after each use; that is normal. To send, select the account, click Send, enter the recipient address and amount, pick a fee level, then review the transaction on the device screen. Confirm only if every detail matches. Never type your 24-word recovery phrase into Ledger Live, a browser, or any other app on the Mac. The phrase belongs on the device or on paper/metal backup kept offline. Also keep macOS updated, use a strong login password, and turn on FileVault so someone with physical access to your Mac cannot read your files.
