How To Factory Reset Macbook Air

What a factory reset means on a MacBook Air

The standard way to factory reset a MacBook Air is to use the Erase All Content and Settings feature in macOS. This removes your user accounts, files, apps, settings, browser data, and saved passwords, then returns the Mac to the initial setup screen. It is more thorough than simply signing out of your Apple Account or deleting selected files.

The reset is irreversible, so back up anything you want to keep before starting. If you are preparing the Mac for sale or donation, removing it from your Apple Account and completing the reset are both essential.

Prepare the MacBook Air

• Create a backup. Use Time Machine, iCloud, or an external drive. Check that important documents, photos, downloads, application data, and software licenses are actually present in the backup rather than assuming they were saved.
• Sign out of iCloud. Open System Settings and select your Apple Account. Choose Sign Out of All Apple Devices, or sign out of iCloud on the Mac if that option is not available.
• Turn off Find My. In the Apple Account settings, select Find My and deactivate it for the MacBook Air. Removing the device from your account helps prevent Activation Lock from tying it to your Apple Account.
• Check other accounts and services. Sign out of email, work, school, VPN, and password-management accounts. If a cellular or eSIM plan is installed, remove it according to your carrier’s instructions.
• Connect the power adapter. Keep the Mac plugged in throughout the reset, especially if macOS needs to download or reinstall itself.

Factory reset the MacBook Air

• Open the Apple menu, choose System Settings, and select General.
• Scroll to the bottom and choose Transfer or Reset, then select Erase All Content and Settings.
• Read the summary of what will be erased and click Continue.
• Enter an administrator password or your Apple Account password when requested. Confirm that you understand the Mac will be erased.
• Allow the process to finish. The Mac may restart several times, download macOS, and display a progress screen. Do not shut it down, close the lid, or disconnect the power adapter.

When the process completes, the Hello setup screen should appear. If the Mac will be used by someone else, do not sign in to your Apple Account. Leave it at this screen so the new owner can configure it.

If “Erase All Content and Settings” is missing

On some older versions of macOS, the option may appear under System Preferences > General > Reset. If it is still unavailable, update macOS first. You can also use macOS Recovery to erase the internal drive and reinstall macOS:

• On a Mac with Apple silicon, shut down the Mac, hold the power button until startup options appear, and select Options > Continue.
• On an Intel-based Mac, restart the Mac and hold Command-R until the startup options or Recovery screen appears.
• Open Disk Utility, identify the built-in internal drive, and erase it using the APFS format. Be careful to select the internal drive, not an attached backup or external drive.
• Quit Disk Utility, choose Reinstall macOS, and follow the on-screen instructions.

After the reset

Complete the setup assistant, reconnect to Wi-Fi, and restore your backup if you are keeping the Mac. Install any software that was not included in the backup and update macOS. Before returning the computer, verify that your files are no longer present, Find My no longer lists the device, and the Mac is resting at the initial setup screen.
