Are you planning to sell your MacBook Air, give it to someone else, or just want to start fresh? A factory reset is the best way to remove all your data and bring your MacBook Air back to its original settings. It’s like giving your Mac a fresh start.
In this guide, you’ll learn how to factory reset MacBook Air in the simplest way possible. Whether you are using a newer model with Apple silicon or an older Intel-based Mac, this step-by-step guide will help you reset your MacBook Air to factory settings without confusion.
Thinking about doing a factory reset on your MacBook Air? You’re not alone. There are several good reasons why this might be the right move for you. Whether you’re cleaning things up, fixing problems, or getting ready to sell, resetting your MacBook can give it a fresh start. Let’s take a closer look at why this can be helpful.
One of the most common reasons to do a factory reset is if you plan to sell, donate, or give away your MacBook Air. You don’t want your personal files, photos, passwords, or documents falling into the wrong hands.
Factory resetting your Mac will:
Erase all your personal data.
Remove your Apple ID and iCloud information.
Give the new owner a clean and fresh setup experience.
Tip: Always sign out of iCloud and disable “Find My Mac” before resetting.
If your MacBook has started to feel sluggish, freeze often, or show random errors, a factory reset might help. Over time, software updates, old apps, and leftover files can slow things down.
Factory resetting your MacBook can:
Clear out old and unnecessary files.
Fix software glitches and bugs.
Make your Mac feel like new again.
Bonus: You can choose to back up your files before the reset using Time Machine or iCloud.
Maybe you’re not selling your Mac, but you still want to wipe everything clean — maybe for peace of mind, or because you’re handing the MacBook to someone else in your home or workplace.
A factory reset will:
Wipe your user profile, saved passwords, and settings.
Remove installed apps and personal content.
Let you set up the Mac again from scratch.
This is especially useful in shared environments like schools or businesses.
Sometimes, the best way to deal with clutter or confusion is to start over with a clean version of macOS. If your Mac feels cluttered or you want to begin with a clean slate, a factory reset is the best option.
Resetting and reinstalling macOS will:
Give you a fresh, clean system with no leftover files.
Help ensure better performance and fewer errors.
Let you install only the apps you truly need.
Good to know: You can reinstall macOS directly from Recovery Mode — no need for USB drives or extra tools.
Before you erase your MacBook Air, it’s very important to back up your data. A factory reset deletes everything on your Mac — documents, photos, apps, and settings.
Use Time Machine or an external hard drive to back up your files. You can also use iCloud or other cloud storage services.
Once you’ve backed up your data, you’re ready to begin.
Before you erase your MacBook Air, you should sign out of iCloud, iMessage, and Find My Mac to make sure your Apple ID is no longer linked to the device.
Go to System Settings or System Preferences.
Click on your Apple ID.
Choose iCloud and turn off Find My Mac.
Scroll down and click Sign Out.
Open the Messages app.
Go to Messages > Settings (or Preferences).
Click iMessage and then Sign Out.
Depending on the chip in your MacBook Air, the steps will differ slightly.
Shut down your Mac.
Press and hold the power button until you see Loading startup options.
Click Options, then Continue.
Restart your Mac.
Immediately press and hold Command + R keys.
Release the keys when you see the Apple logo or a spinning globe.
This will start your Mac in macOS Recovery Mode.
Once you’re in macOS Recovery:
Click Disk Utility and then click Continue.
In the sidebar, choose Macintosh HD or the name of your startup disk.
Click Erase at the top.
Choose APFS or Mac OS Extended (Journaled) as the format.
Click Erase again to confirm.
Your disk will now be erased. This step deletes all your data and prepares your MacBook Air for a clean installation.
After you erase the disk:
Close Disk Utility to go back to the macOS Utilities screen.
Select Reinstall macOS and click Continue.
Follow the instructions on the screen to reinstall macOS.
Your MacBook Air will now download and install the latest version of macOS that is compatible with your device.
Once the reset is complete:
Your Mac will restart.
You’ll see the setup assistant — just like when you first got your Mac.
If you’re selling or giving it away, do not set it up. Let the new user do that.
If you have a MacBook Air from earlier years, such as 2013, 2017, or 2018, the process is similar. The key difference is whether your device uses Apple silicon or an Intel processor. Always check your Mac’s chip type in About This Mac under the Apple menu.
For older models:
Use Command + R during startup.
Choose Disk Utility to erase the drive.
Then, reinstall the operating system.
If you forgot your password and can’t log in, you can still factory reset your Mac:
Turn off the MacBook Air.
Start Recovery Mode (use the method based on your chip).
Use Disk Utility to erase the drive.
Reinstall macOS.
Note: If Activation Lock is enabled, you will need the Apple ID and password used to set up the Mac. Otherwise, you won’t be able to complete the reset.
If you just want to fix some issues but don’t want to lose your files, you can reinstall macOS without erasing the disk:
Start your Mac in Recovery Mode.
Choose Reinstall macOS (do not erase the disk).
Follow the on-screen steps.
Your files and apps will stay, but macOS will be refreshed.
On newer macOS versions, there’s a faster method using Erase Assistant:
Go to System Settings > General > Transfer or Reset.
Click Erase All Content and Settings.
Enter your password.
Follow the prompts to erase and reset.
