Things to Know
After making a backup of your MacBook Air, log out of all other services, including iCloud and iTunes.
Select Disk Utility > View > Show All Devices when in Recovery Mode. Select Hard Drive > Erase.
Click Erase and select APFS (High Sierra or later) or Mac OS Extended (Journaled) (earlier macOS). Click Reinstall macOS under the Utilities menu.
If you want to sell your MacBook Air or have unfixable performance issues, this article will show you how to reset it to factory settings. It contains instructions on how to reinstall macOS, create a backup using Time Machine, and sign out of various Apple services like iCloud and Message. It works with OS X Yosemite through macOS Big Sur (11). (10.10).
Establish a Backup
Make a backup of the MacBook Air before you start, particularly if you intend to use it again or transfer your information and documents to a new Mac.
Time Machine, a preinstalled Apple tool that backs up your stuff, including music, images, and apps, to an external drive, is a popular method of securing your data. Here’s how to use Time Machine to make a backup:
Connect a Mac to an external storage device.
In the top-left corner of the screen, click the Apple icon.
Select System Preferences.
Press Time Machine.
Select Backup Disk by clicking.
Select your external drive, then select Use Disk and Encrypt Backups.
If the ON button in the Time Machine window’s left column is not already selected, click it.
A backup of your MacBook Air is started by Time Machine after you click Use Disk or ON.
You can later restore this backup by connecting your external hard drive to the Mac and following the on-screen directions after your MacBook Air has been returned to its factory settings.
Most MacBook Air users are often advised to utilise Time Machine, however it is limited in what it can do. A bootable clone of your MacBook Air is something you’ll need if you want your MacBook (or another MacBook Air) to function exactly as it did before, even though it copies your files and apps.
As a result, you may want to think about using a free backup tool from a third party, like SuperDuper or Carbon Copy Cleaner.
Sign Out of Your iServices
If you’re resetting your MacBook Air in order to sell or give it away, there is one little but crucial step you should take. This entails logging out of any Apple services that are currently active on your Macbook, including iMessage, iCloud, and iTunes.
iCloud Sign Out Instructions
On the MacBook Air’s screen, click the Apple icon in the upper-left corner.
Select System Preferences.
In macOS Catalina (10.15) and later, click Apple ID. (For earlier iterations, select iCloud.)
In versions of macOS Catalina (10.15) and later, click Overview and Sign Out. (Select Sign Out in earlier versions of macOS.)
How to Sign Out of iTunes
Open iTunes in macOS Mojave (10.14) and earlier or the Music app in macOS Catalina (10.15) and later.
Click Account in the menu bar at the top of the MacBook Air’s screen.
Click Authorizations in the drop-down menu that displays.
To unauthorize this computer, click.
Your Apple ID and password must be entered.
Deauthorize by clicking.
How to Sign Out of Messages
Launch the messaging app.
In the menu bar at the top of the Mac’s screen, select Messages.
Then select Preferences.
On the iMessage tab, click.
To the right of your Apple ID, select the Sign Out button.

That concludes the procedures you must follow if you intend to sell your MacBook Air or donate it to a friend or member of your family. The exact process of resetting it follows.
Reset the Factory Settings
Your Mac has to be online in order to restore your MacBook Air to factory settings. Your Mac must first start in Recovery Mode. To accomplish this, restart your MacBook Air or turn it on while pressing and holding Command+R until the Apple logo appears.
You see the Utilities window once the Apple logo displays and the computer has finished setting up. You can reset and erase your hard drive from this page. How to do it is as follows:
Then select Disk Utility.
Then click Next.
To view all devices, select View.
By selecting it and clicking Erase.
On macOS High Sierra or later, select the APFS option in the Format field. Select Mac OS Extended (Journaled) on macOS Sierra or earlier.
When you erase the SSD in your MacBook Air, there is no undo option available. Before pressing Erase, exercise caution and make sure you have a backup of all your data.
The hard drive of your MacBook Air will thereafter be completely cleaned. It can require several minutes to finish. You can reinstall macOS after it is finished, as seen below:
Click Reinstall macOS under the Utilities menu.
Then click Next.
To finish the installation, adhere to the on-screen directions.
Once the installation is complete and you reach the Welcome screen on your new Mac, do not continue with the setup if you want to sell or give away your MacBook Air. Press Command+Q and then click Shut Down to end the installation after it is finished and leave the MacBook Air in its original state.
If you do that, the MacBook Air will begin the setup procedure just as it did when it was first powered on the next time it is switched on.
Erasing Content and Settings in macOS Monterey and Later
You have another, simpler option in your System Preferences if your MacBook Air is running macOS Monterey (12.0) or later. Without removing the operating system, you can execute a clean reset using the Erase Content and Settings tool.
It functions similarly to the iPhone’s Erase All Content and Settings functionality and gives you a faster way to clean up your device without entirely deleting it.
Open System Preferences and choose Erase All Content and Settings from the System Preferences menu to activate this option.
The Benefits of Resetting Your MacBook Air
Even though you wouldn’t typically do this when your MacBook Air is in optimal condition, there are a number of situations where you might want to or need to reset it.
Resetting a MacBook Air is most frequently done by those who are selling them. Resetting your MacBook is necessary in this situation since you don’t want to give a stranger access to a repository of your personal information.
To sell the computer without jeopardising your security and privacy, you must remove all of your personal data and settings from it.
Resolving performance problems is a further justification for restarting a MacBook Air. It could be time to restore your Mac to factory settings if it has been running slowly and you have explored every option for optimising your Mac and enhancing its speed and performance.
Although it’s a last resort, this tactic frequently succeeds. The MacBook Air is in a comparable condition after the reset as it was when it was originally taken out of the box.
Resetting a MacBook Pro involves essentially the same processes as resetting a MacBook Air.
