How to Switch Users on Mac

What do you need before switching users on Mac?

Before you can switch to a different user on Mac, a few things need to be in place. The most obvious one—you need more than one user account set up on your Macintosh. If you’re the only person using the laptop, you might not have additional accounts at all.

Here’s what to check:

• Multiple user accounts. You’ll need at least two accounts—admin, standard, or guest—created in System Settings > Users & Groups.
• Admin access. Some switching methods (like enabling fast user switching) require an admin account. If you forgotten admin password, we’ll remind you to reset it before proceeding.
• Account passwords. Each user account on macOS needs a password (or Touch ID) to log in. Make sure every user knows their credentials.
• macOS version awareness. Menu labels differ slightly between macOS versions—Ventura and Sonoma use System Settings, while older releases like Monterey use System Preferences.

A note from our experts: 

 

While switching users on your Mac, you might be more or less concerned about your data privacy and the safety of each of your accounts. If so, you might be interested in safeguarding your emails and preventing a data breach.

 

Do it smartly with MacKeeper’s ID Theft Guard:

1. Download MacKeeper, install it, and launch the app.
2. Find the ID Theft Guard functionality on the left and click on it.
3. Activate the Data breach monitor function.
4. Then click to Scan new email and type in the field.
5. After typing your email, press Start Scan.

Once these basics are covered, you’re ready to select a different user on a Mac using any of the methods below.

How to select a different user on Mac?

macOS offers multiple ways to switch between users on Mac—and the method you pick depends on your situation. Need to toggle accounts without closing anything? Fast user switching is your go-to. Want to free up memory? Logging out first is the smarter choice.

If someone needs temporary access to your Apple laptop, you can also add a guest account so they can browse without touching your files. Let’s walk through each method.

1. Fast user switching

Fast user switching is the quickest way to use a different user on Mac. It lets you jump to another account straight from the menu bar or Control Center—without logging out of your current session. Your apps, documents, and windows stay right where you left them.

The trade-off? Because both accounts stay active in the background, your Mac uses more memory. On laptops like the MacBook Air with limited RAM, this can slow things down if too many users are logged in at once.

Here’s how to switch users with fast user switching:

1. Click the Fast User Switching icon (a person silhouette or your account name) in the menu bar.
2. Select the account you want to switch to from the dropdown.
3. Enter the password for that account and press Return.

If you don’t see the fast user switching icon, you’ll need to enable it first—we’ll cover that in the section below.

2. Switch users from Lock Screen

If your Mac goes to sleep or you’ve stepped away, the Lock Screen is a natural place to switch between users on Mac. We’d say that it’s especially handy in shared spaces—an office, a classroom, or a family desk—where people take turns at the same machine.

To switch users from the Lock Screen:

1. Go to the Apple menu and click Lock Screen. Or press Control + Command + Q to lock it instantly.
2. On the Lock Screen, tap the user icon located at the bottom of the lock screen. This will expand the Multiple users section, allowing you to switch user accounts.
3. Choose the account you’d like to log in to.
4. Enter the password and press Return.

3. Log out and sign in to another account

This is the traditional way to choose a different user on Mac. When you log out, macOS closes your session entirely—freeing up memory, CPU, and disk resources that the account was using. From our point of view, it’s the cleanest method, though it does mean you’ll need to reopen your apps and documents when you log back in.

To log out and sign in as another user:

1. Click the Apple menu in the top-left corner of the screen and select Log Out.
2. Confirm by clicking Log Out in the dialog box.
3. On the login screen, click the user account you want to access.
4. Type the password and press Return.

An extra tip from us: If you have unsaved work, macOS will ask whether you’d like to save before logging out. Don’t dismiss this prompt too quickly—it’s easy to lose changes.

4. Use keyboard shortcuts to switch users

If you prefer keeping your hands on the keyboard, macOS offers shortcuts that speed up switching. These won’t switch you directly to another account, but they’ll get you to the login screen in a flash.

Here are the key combos:

• Control + Command + Q—locks the screen and shows the login window. From there, click Switch User and pick a different account.
• Shift + Command + Q—logs you out of the current account entirely and takes you to the login screen.

Be aware that macOS includes many handy keyboard shortcuts that help streamline everyday tasks, such as switching between users and switching between tasks. Use this opportunity to save your time!

5. Switch users through Terminal

Terminal isn’t the go-to tool for everyday account switching, but it’s useful when you need to access another user’s files or run commands with different permissions. Think of it as a behind-the-scenes approach rather than a visual toggle between accounts.

Here’s how to switch to another user environment in Terminal:

1. Open Terminal from Applications > Utilities.
2. Type login and press Return.
3. When prompted, enter the username of the account you want to access.
4. Type the password for that account and press Return.

A hint from our team: You can also use the su command (e.g., su - username) to switch user identity in the same Terminal window. Keep in mind that this method doesn’t change the macOS desktop—it only switches your command-line environment.

6. Use Touch ID

If your MacBook Pro, MacBook Air, or Magic Keyboard has Touch ID, switching accounts is as simple as placing your finger on the sensor. Each user registers their own fingerprint, and macOS recognizes who’s logging in automatically—no typing required.

To set up Touch ID for user switching:

1. Sign in to the account you want to configure.
2. Go to Apple menu > System Settings > Touch ID & Password.
3. Click Add Fingerprint and follow the on-screen prompts to register your finger.
4. Toggle on Use Touch ID for fast user switching.
5. Repeat for each user account on the Mac.

Once set up, just press Touch ID at the Lock Screen or login window. macOS will identify which user’s fingerprint it detects and switch to that account instantly. If the Touch ID not working on Mac, it may be due to settings issues, software glitches, or other causes.

How to enable fast user switching on Mac?

Fast user switching isn’t enabled by default on macOS, so you’ll need to turn it on before you can use it from the menu bar or Control Center. You’ll need admin permissions to make this change.

Follow these steps to enable it:

1. Click on the Apple logo in the top-left corner of your screen.
2. Select System Settings (or System Preferences on older OS) from the dropdown menu.
3. Go to the Menu Bar section (or Dock & Menu Bar, depending on your macOS version).
4. Scroll down and find Fast User Switching.
5. Enable Fast User Switching.
6. Choose how you’d like the switcher to appear—Full Name, Account Name, or Icon.
7. In the same Menu Bar section, select Menu Bar Controls.
8. Choose Add Controls, then scroll down to the Fast User Switching option.
9. Select Icon, then click Add to the Control Center.
10. Open the Control Center from the top-right corner of the menu bar and verify that the Fast User Switching icon appears correctly.

A lifehack for you: 

 

On older macOS versions, go to System Preferences > Users & Groups > Login Options and select Show fast user switching menu as.
