How to Reset a MacBook Air in 9 Steps

Do you want to learn how to reset your MacBook Air? Whether your MacBook Air has been having technical issues, showing slow performance, or it just doesn’t function like it used to, it could be time for a reset. In addition, if you’re planning on selling or giving your MacBook Air to a friend, then you may want to perform a factory reset to remove all of your data.

Luckily, resetting your MacBook Air is a fairly straightforward process and doesn’t require any advanced tech know-how. You’ll simply be using built-in settings that your MacBook already has. In this guide, we’ll walk you through the process of resetting your MacBook Air, step-by-step.

Why Do You Need to Reset Your MacBook Air?

There are a variety of reasons you’ll want to reset your MacBook Air. First, it can help resolve software issues. Your MacBook may be experiencing issues due to software conflicts, corrupted files, or improperly installed updates. Resetting your MacBook will restore your device to factory settings and remove these issues.

Another common reason is sluggish performance. Over time, your MacBook Air can accumulate a lot of unnecessary files, apps, and settings that can slow down its performance. A factory reset can help improve your device’s speed and efficiency by removing all of this digital clutter.

Finally, if you’re planning to sell or give away your MacBook Air, it’s important to reset it to factory settings to remove all your data, files, and settings. This ensures that the new owner starts with a clean slate and protects your privacy.

Step 1. Prepare for the MacBook Air Reset

Before you do anything, you’ll want to make sure your MacBook Air is ready for a reset. This will ensure the process goes as smoothly as possible and you don’t lose any data, or corrupt your MacBook. First, connect your MacBook Air to a power source. This will help you avoid any interruptions due to a low battery. Then, make sure you have a stable internet connection since you’ll need to download the latest macOS version during the reset process.

Step 2. Back Up Your Macbook Air Data

Resetting your MacBook Air will erase all of your data, including documents, photos, and applications. Therefore, it’s crucial to back up your important files before moving forward. You can use Time Machine, Apple’s built-in backup solution, or a third-party tool to create a backup of your MacBook Air. Alternatively, you can plug in an external drive and upload all the files that you want to save. Note that this option won’t back up your application and system data.

To back up your computer with Time Machine, start by connecting an external drive to your MacBook Air. Once connected, click on the Apple menu located at the top-left corner of the screen and select “System Settings.” Then, within the System Settings window, click on “General” and click the “Time Machine” option.

After that, click “Add Backup Disk” and a list of available drives will appear. Select the external drive where you want your backups to be saved. Finally, toggle the “Back Up Automatically” option to enable automatic backups and Time Machine will start creating a backup of your MacBook Air. The initial backup may take some time, depending on the size of your data, but future backups will be quicker since Time Machine will only back up new or modified files.

Click on the “Add Backup Disk…” button at the bottom right of the prompt, then select your hard drive.


Step 3. Disable FileVault

FileVault is an encryption feature that helps protect your data by encrypting your MacBook Air’s hard drive. This helps keep all of your sensitive data private and safe. But, before you reset your MacBook Air, it’s important to disable this feature to avoid potential complications during the process.

To disable FileVault on your MacBook Air, start by clicking on the Apple menu located at the top-left corner of the screen, and then select “System Settings.” In the System Settings window, choose the “Privacy & Security” option. Once the window opens, click “Turn Off…”.

Next, you’ll be prompted to enter your administrator password. In the next pop-up, you can click “Turn Off Encryption.” This may take some time, depending on the size of your encrypted data, as your MacBook Air will need to decrypt the files.

Step 4. Sign Out of iCloud and Other Applications

To avoid potential issues with Apple services after the reset, sign out of iCloud and iMessage on your MacBook Air. First, click on the Apple logo located in the upper left corner of your screen. From the dropdown menu, select “System Settings.” Next, click on your “Apple ID” icon. Then, scroll to the bottom and click “Sign Out”. This will sign you out of iCloud, iMessage, and any other accounts associated with your login.

Once it’s off, press and hold the power button until a startup options window pops up. Then, click on the gear icon labeled “Options” and click on “Continue”. This will now start MacOS recovery mode. You may be prompted to enter a password for a user account.

A new window will open, prompting you to choose a format and enter a new name for your hard drive if desired. Select “APFS” as the format, and input a name for your hard drive if you want to change it. Finally, click the “Erase” button to initiate the process.

Scroll down until you find the “Reinstall macOS” option. It will install the latest version of MacOS onto your MacBook.


After that, a series of on-screen instructions will guide you. These will help you choose your hard drive and install the latest version of macOS on your MacBook. Simply follow these instructions to complete the reinstallation process, and you’ll have a fresh installation of macOS on your device. The installation process may take some time, so be patient.

Step 8. Set Up Your MacBook Air as a New Device

Once the macOS installation is complete, your MacBook Air will restart. You can now set up your MacBook Air as a new device, by following the on-screen instructions. If you’re planning to sell or give away your MacBook Air, you can stop at the “Welcome” screen and let the new owner complete the setup process.

Step 9. Restoring a Previous Time Machine Backup

If you backed up your MacBook with Time Machine and want to restore a previous backup, then you can do so now. If you want to only restore certain files, then you can open up Time Machine and select those files. It will automatically restore those files to the previously backed up version.

You can also restore your entire system to a previous state. If you want to do this, you need to make sure you’ve connected your external drive containing the Time Machine backup to your Mac. Next, power off your Mac. Then, turn it on and keep pressing the power button until the macOS Recovery mode screen appears. Here, you’ll be presented with the “macOS Utilities” window. Choose the “Restore from Time Machine Backup” option and click “Continue.”

Scroll down until you find the “Restore from Time Machine” option. It will restore your previous data from your backup onto your MacBook.


A new window will pop up that provides an overview of the Time Machine restoration process. Simply click “Continue” again to move forward. You will then see a list of available Time Machine backups. Select the specific backup you want to restore and click “Continue.”

After selecting the desired backup, you’ll need to choose the destination disk for the restoration. This will typically be your Mac’s internal drive. Select the drive you want and click “Restore” or “Continue,” depending on your macOS version. This process may take some time, depending on the backup size and your external drive’s speed. Once the restoration is complete, your Mac will restart automatically.
