It pays to know how to factory reset MacBook Air. Especially if you wish to sell your device, gift it, or troubleshoot a persistent issue. It will erase all your data and return your MacBook to its purchase state.

The whole process is easy. We’ll show you step by step how to factory reset MacBook Air.

What is a Factory Reset?

A factory reset gives your MacBook Air a fresh start. It’s a hard reset that removes all the data, apps, and settings from your MacBook Air. This restores it to how you first took it out of the box.

Factory resets are handy if you’re troubleshooting persistent problems. The same goes if you’re planning to sell or give your MacBook to someone else, or want to start cleaning it.

Preparation Before Resetting Your MacBook Air

The hard reset wipes out everything you have added to your MacBook. The settings, photos, apps, files, and other pieces of data will go puff. That’s why you need to prepare thoroughly before you click ‘erase’.

Here’s important steps you need to take before resetting your MacBook Air.

Backup Your Data

Backing up your data is important because a factory reset will erase everything on your MacBook Air.

You risk losing all your files, photos, and important documents without a backup. Imagine losing all your vacation photos, work files, or personal projects.

There are three methods you can use to back up your data:

  • Time Machine Backup: Use Time Machine to create a full backup on an external drive. Before you load the erase assistant, the Time Machine can back up files on your Mac that weren’t part of the macOS installation. We’re talking apps, music, photos, and documents.
    This built-in feature makes restoring your data easy after the reset. Connect an external storage device, go to System Preferences, and select Time Machine to start the backup process.
  • External Hard Drive: Manually copy important files and folders to an external hard drive for safekeeping. This method is straightforward. Drag and drop your vital files to the external storage device.
  • iCloud: Sync your data to iCloud for a cloud-based backup. You can access your files from any device with your Apple ID.
    To do this, go to System Preferences, click on your Apple ID, and enable iCloud Drive. Ensure you have enough storage space on iCloud to back up all your files. Remember, the erase assistant may sign out of iCloud on your device.

Sign Out of Accounts

Before resetting, sign out of all your accounts to ensure your data is removed and your accounts are secure.

  • Sign out of iCloud: Go to System Preferences, click on your Apple ID, and select Overview. Click the Sign Out button to ensure your iCloud data is removed from the device. You can sign back into another device using your Apple ID password.
  • Sign Out of iTunes: Open iTunes, go to Account in the Apple menu bar, and select Sign Out. This deauthorizes the device from your iTunes account.
  • Sign Out of iMessage: Open the Messages app, go to Preferences, select the iMessage tab, and click the Sign Out tab.
    This prevents your messages from being accessible on the device. It’s an essential step to protect your privacy. It ensures no one else can read your conversations.

Deauthorize Your MacBook Air

Deauthorizing your MacBook Air prevents issues later with your accounts and services.

  • Deauthorize from iTunes: In iTunes, go to Account, then Authorizations, and select Deauthorize This Computer. This removes your MacBook Air’s access to your iTunes account. It’s necessary, especially if you plan to sell or give away your MacBook.
  • Other Services That May Require Deauthorization: Deauthorize any other services or apps linked to your MacBook Air. These include Adobe Creative Cloud or other subscription-based software.
    Check the apps you frequently use and look for any deauthorization steps in their settings. Check account management sections for any apps that use your Apple ID password.
