Does your MacBook Air or MacBook Pro seem a little long in the tooth? Is there an issue you can’t seem to solve no matter how you try? Or do you want to sell your MacBook without a trace of personal data on it? Here's our guide on how to reset a MacBook — or any Mac computer — to solve any of those issues.
Below, we explain how to completely factory reset your MacBook (or iMac) to a like-new state. The instructions below (with a few minor tweaks here or there, depending on your exact machine) will work for macOS Big Sur and most older versions of the operating system.
Before you do this, be sure to back up your data. If you’re selling your MacBook, also make sure to sign out of iMessage, iCloud and any other accounts before you reset.

5. If you don't need to do any backing up, just click continue, to see all the content that will be erased. If you're happy with it all being deleted, click continue again.
6. Here, you'll be asked to enter your Apple ID info, and given another dialog box to confirm you want to factory reset your Mac.
7. If you're sure, click Erase All Content & Settings and leave the laptop for 5-10 minutes to sort itself out.

What to do before you reset your MacBook
The guide above is focused on resetting your MacBook, but there are recommended actions to take before factory resetting your MacBook that you should be aware of. These pointers will ensure that you don't lose any personal files, photos or apps when you move from one MacBook to another.
- Back up your MacBook. We can't overstate the importance of this step. Creating a backup will protect your most valuable files. If you don't back up your data, it will disappear into the ether when you perform a factory reset.
- Sign out of iTunes. Choose Account > Authorizations > Deauthorize This Computer. If you're running the latest macOS, you can skip this step.
- Sign out of iCloud. Hit the Apple menu, go to System Preferences then click the Apple ID. Choose iCloud from the side panel and Turn off Find my Mac. Then click Overview and Sign out.
- Sign out of iMessage. Open the Messages app, choose Messages then Preferences. Click iMessage and Sign Out.
- Unpair Bluetooth devices. Go to the Apple menu > System Preferences and choose Bluetooth. Here, you can unpair keyboards, headphones or other Bluetooth-enabled peripherals.
Now you know how to factory reset a MacBook or any Mac computer!
From here, if you’re looking to sell your computer, you’re all done — no need to worry about the new owner getting into your files or apps. If you want to get back to the desktop, follow the prompts as if you were setting up your MacBook for the first time.
