How To Factory Reset Macbook Air

What a Factory Reset Does

A factory reset returns a MacBook Air to a clean state by erasing personal files, applications, accounts, and system preferences. On a Mac, the usual method is called Erase All Content and Settings. It is appropriate when troubleshooting persistent software problems, preparing to sell or give away the computer, or starting over with a fresh user profile.

This process is not a substitute for a normal backup. Erased data may be difficult or impossible to recover, so complete the preparation steps below before continuing.

Prepare Before Resetting

• Back up your files. Use Time Machine, iCloud, an external drive, or another trusted backup method. Verify that important documents and photos can be opened from the backup.
• Transfer what you still need. Move files, music, browser bookmarks, and other data to an external drive or another computer.
• Record your Apple Account details. You may need your Apple Account email address and password during setup. You will also need the Mac’s administrator password if one is set.
• Sign out of iCloud and other services. On Apple silicon models, use the standard sign-out process to remove the Mac from your Apple Account. On Intel models, remove the device from Find My and iCloud before erasing it.
• Disconnect unnecessary accessories. USB drives, external disks, SD cards, and other devices can complicate erasing or reinstallation.
• Connect power. Keep the MacBook Air plugged in throughout the reset, and use a reliable internet connection when prompted.

If the Mac is managed by a school or company, do not erase it yourself. Ask the administrator to return it or perform an approved reset.

Use Erase All Content and Settings

This is the simplest and recommended method on a supported Mac running a current version of macOS.

1. Open Apple menu and choose System Settings.
2. Select your Apple Account name at the top of the sidebar, then select Find My.
3. Turn off Find My if you are preparing the Mac for another person. Confirm any requested password.
4. Return to System Settings and choose General.
5. Select Transfer or Reset, then choose Erase All Content and Settings.
6. Follow the onscreen instructions. macOS may ask for your password, sign you out of services, erase the user profile, and reinstall macOS.

Allow the process to finish without forcing a restart or closing the lid. When it ends, the Mac should display the setup assistant. If an error appears, make sure the computer is connected to power and the internet, then try again.

Reset macOS Using Recovery

Use Recovery when Erase All Content and Settings is unavailable, macOS will not start normally, or you need a more complete reinstallation. Start with a backup and the Apple Account credentials associated with the device.

On Apple silicon Macs, shut down the computer, hold the Touch ID button or power button until startup options appear, and then select Options followed by Continue. Choose Disk Utility, select the internal Mac drive, and erase it using the suggested APFS format. Return to the main menu and choose Reinstall macOS.

On Intel Macs, restart the computer and hold the Command and R keys until the startup options or recovery utilities appear. Open Disk Utility, erase the internal drive, and then select Reinstall macOS. Be careful to identify the internal drive rather than an external disk.

After the Reset

Complete the macOS setup assistant, reconnect accessories one at a time, and restore only the data you need. Install trusted applications and update macOS. If the Mac was previously used with a work or school account, contact that organization’s administrator before signing in again.

Never sell or donate a Mac until the setup screen appears and you have confirmed that the new owner can activate it. Keeping the device connected to your Apple Account can leave an Activation Lock, which may be difficult to remove later.
