How to Factory Reset Your MacBook Air Quickly and Safely
Factory resetting a MacBook Air is often the final solution to persistent software issues or a necessary step before selling or giving away your device to ensure all personal data is removed.
Whatever your reason, this guide will walk you through the complete process of how to factory reset your MacBook Air safely and effectively.
How to Factory Reset Your MacBook Air
Before diving into the entire process of wiping your MacBook Air, you need to perform a backup to prevent losing files vital to you. Thankfully, Apple already provided a system utility, Time Machine, dedicated to this course. Time Machine allows you to backup files such as apps, photos, music, etc.
How to Back up Files on MacBook Air
- Get external storage and connect it to your Mac
- Select the Apple icon in the top-left corner of the desktop and click System Preference
- Select Time Machine from the menu
- Next, click Select Backup Disk
- You should find the external storage you connected earlier. Click on it and select Encrypt Backups > Use Disk.
- Finally, on the Time Machine screen, use the ON button to initiate the backup process.
Once the backup is complete, you can factory reset your MacBook Air. All you need to do to get back the files backed up on the same or another MacBook Air is to connect the external storage to the MacBook Air and follow the prompts on the Restore page.
How to Perform a Factory Reset on Your MacBook Air
Make sure your MacBook Air is connected to a stable Wi-Fi network before starting the reset. Also, disconnect any external devices to avoid interruptions.
When the installation completes and the Mac restarts to the Welcome screen, press Command + Q to shut down if you plan to sell or give away the Mac. This allows the new owner to complete setup with their own information.
- Shut down your MacBook Air completely.
- Turn it on and immediately press and hold Command (⌘) + R keys together to boot into macOS Recovery Mode. Keep holding until you see the Apple logo or a spinning globe.
- In the macOS Utilities window, select Disk Utility and click Continue.
- Click View in the top-left corner and choose Show All Devices.
- Select your internal startup disk (usually named “Macintosh HD”).
- Click Erase at the top of the Disk Utility window.
- Choose a name for the disk (e.g., Macintosh HD), select the appropriate format:
APFS for macOS High Sierra (10.13) and later,
Mac OS Extended (Journaled) for earlier versions. - Set the scheme to GUID Partition Map if available.
- Click Erase to wipe the disk.
- When the erase process finishes, close Disk Utility to return to the macOS Utilities window.
- Select Reinstall macOS and follow the on-screen instructions to reinstall the operating system.
How to Factory Reset MacBook Air Without Password
If you don’t know the password or are locked out, you can still factory reset your MacBook Air by booting into Recovery Mode as described above. However, if your Mac has Activation Lock enabled (linked to your Apple ID), you will need the Apple ID and password to disable it after the reset.
For Macs with Apple Silicon (M1 or later), the process to enter Recovery Mode is slightly different:
- Shut down your Mac.
- Press and hold the power button until you see “Loading startup options.”
- Select Options and click Continue to enter Recovery Mode.
Does Factory Reset Delete Everything on MacBook Air?
Yes, performing a factory reset erases all data, settings, and installed applications from your MacBook Air’s internal drive. This process restores the Mac to its original factory state with a fresh installation of macOS. However, data stored on external drives or cloud services will remain unaffected.
Because the reset permanently deletes all local data, backing up beforehand is essential if you want to keep your files.
Final Notes
Your MacBook Air should return to a factory-new state with the format complete. However, note that there is no undo button for a factory reset. All files erased without a backup (in case of data loss, consider using Mac Data Recovery Software) are gone forever and cannot be recovered. Therefore, ensure to follow the backup steps demonstrated earlier diligently.
