Whether you’re planning to sell your MacBook or Mac, encountering persistent software issues, or simply wanting to start afresh with a clean slate, performing a factory reset is a practical solution.
However, the process may seem daunting if you’re unfamiliar with the steps involved. In this guide, I’ll show you how to factory reset your MacBook or Mac, providing step-by-step instructions, helpful tips, and troubleshooting advice to ensure a smooth experience.
Preparing for a Factory Reset
Before proceeding with a factory reset, it is crucial to back up your data on your Mac to prevent potential loss.
There are different ways to back up your data, but I prefer using Time Machine because it’s the most reliable one. Follow these steps to create a backup using Time Machine:
- Connect an external hard drive or SSD to your Mac.
- Click the Apple icon in the menu bar and select System Settings.
- Click General and select Time Machine.
- Tap the Add Backup Disk button and choose the external hard drive you connected.
- Once selected, Time Machine will automatically start backing up your data.
By backing up your data, you can ensure that your important files and documents remain safe and can be easily restored after the factory reset.
How to Factory Reset Your MacBook or Mac
Now that your data has been backed up, you can move on with the factory reset.
1. Erase Your Mac With an M1/M2 Chip
Apple launched macOS Monterey in 2021, introducing a new feature called Erase All Content and Settings in System Preferences (renamed System Settings in macOS Ventura) that allows you to restore your Mac to its original factory settings.
The Erase All Content and Settings option simplifies the process of wiping your Mac for resale, transfer, or for a clean installation to potentially resolve system issues.
The Erase All Content and Settings feature requires an M1 or M2 series Mac or a Mac equipped with a T2 chip. Moreover, your system must be running either macOS Monterey or macOS Ventura.
Here’s how to erase your M1/M2/T2 Mac and reset it to its factory settings:
- Click the Apple menu and select System Settings.
- Click General and select Transfer or Reset.
- In the Transfer or Reset menu, click the Erase All Content and Settings button.
- Enter your admin password and click Unlock.
- Click Continue to proceed with the erasing process in the macOS Erase Assistant.
- If asked, sign out of your Apple ID account.
- Click Erase All Content & Settings.
- After resetting your Mac, it will reboot and display a black screen.
- You will be prompted to select a language and a Wi-Fi network during this process. When you successfully connect to the network, your Mac will become activated, and you’ll see a message on the screen indicating that Your Mac is Activated.
- To proceed with the setup, simply click the Restart button.
2. Erase Your Mac With an Intel Processor
Erasing an Intel-based Mac without a T2 chip involves a different process than erasing an M1 or M2 Mac. You have to log out of various services, unlink accounts, and disconnect Bluetooth devices.
Here’s how to erase your Mac with an Intel processor:
- Log out of Find My: Navigate to System Settings and select your name under the Apple ID/iCloud section. In the Find My Mac section, click Options, then select Turn Off next to Find My Mac and Find My Network.
- Log out of iMessage: Open the Messages app on your Mac. Click Messages in the menu bar, then Settings/Preferences, choose the iMessage tab and click Sign out.
- Deauthorise and log out of your Music/iTunes account: It’s important to do this as you can only use up to 5 Macs to play music associated with your account. To do this, open the Music app, click Account, then Authorisations, and select De-authorise this computer. Subsequently, go to Account and click Sign out.
- Sign out of your TV account: Similar to the Music app, you’re limited in the number of devices that can play movies purchased from the iTunes Store. To sign out, open the TV app, select Account, then Authorisations, and De-authorise this computer. Then, go to Account and click Sign out.
- Sign out of iCloud: In System Preferences, click your name in the Apple ID/iCloud section and sign out. If prompted to keep a copy of the iCloud data on your Mac, deselect all options (after ensuring you’ve backed up this data elsewhere). Click Continue and allow the sign-out process to complete.
If you use iCloud Photo Library, you’ll be asked if you want to download photos to the Mac (only necessary if you want to back up this cloud-based library). Finally, enter your Apple ID password to confirm your Mac’s password.
You may consider resetting the NVRAM to thoroughly clean up your personal Mac settings. I have shared the step-by-step process for resetting your Mac’s NVRAM or PRAM in this guide.
3. Unpair Bluetooth Devices
Unpairing Bluetooth devices from your Mac is a simple process. Here’s how to do it:
- Click the Apple menu in the upper-left corner of your screen, then select System Settings.
- In the window that opens, click Bluetooth.
- In the Bluetooth settings window, you’ll see a list of devices paired with your Mac. Find the device you want to unpair and click its name.
- Next to the selected device’s name, click the x button. A dialog box will pop up asking you to confirm that you want to remove the device. Click Remove.
- Once you’ve confirmed, the device will be removed from your list of paired devices.
Remember, unpairing a Bluetooth device means it won’t automatically connect to your Mac in the future. If you want to use the device with your Mac again, you must go through the pairing process.
4. Turn Off FileVault
FileVault is a disk encryption program available in Mac OS X 10.3 and later. If you’ve been using it, you need to turn it off before resetting your Mac to its factory settings.
Follow these steps to turn off FileVault disk encryption on your Mac:
- Head to the System Settings via the Apple icon at the top.
- Select Privacy & Security and find the FileVault section in the right panel. Tap the Turn Off… button. (It will appear if you have enabled FileVault on your Mac).
- Enter the administrator username and password, and click Unlock.
- After you’ve turned off FileVault, your Mac will start decrypting your hard drive. This could take a while, especially if you have a lot of files. It’s best to keep your Mac plugged in and awake during this time.
Turning off FileVault means your files won’t be encrypted. If someone gains access to your Mac, they could access your files. So it’s usually a good idea to keep FileVault turned on unless you have a specific reason to turn it off.
5. Restart your Mac in Recovery Mode
After successfully backing up all your data, unlinking your accounts, and unpairing devices, you’re now prepared to erase your Mac completely.
To begin this process, you’ll need to boot your Mac into Recovery Mode. This state allows you to clear all data from your Mac safely. Here’s how to restart your M1 Mac in Recovery mode:
- Shut down your Mac by choosing the Apple menu > Shut Down.
- Press the Power button until you see Loading startup options.
- Click Options, then click Continue.
- Select your language, then click Next.
- Click Utilities > Startup Security Utility.
- Enter your administrator password, and click OK.
- Select Full Security under Startup Security, then click Restart.
- Press the Power button until you see Loading startup options again.
- Click Options, then click Continue to boot Mac into Recovery Mode.
Here’s how to boot an Intel-based Mac into Recovery Mode:
- Shut down your Mac and wait for it to power off fully.
- Press the Power button to start up your Mac.
- Immediately press and hold the Command ⌘ + R keys.
- Keep holding both keys until the macOS Recovery screen appears.
- If prompted, provide your administrator password to log in to your user account.
6. Erase Your Startup Disk
To erase and reformat your Mac, you will need to start up in Recovery Mode. Now that you have booted up your Mac in Recovery Mode, here’s a step-by-step guide on how to erase your startup disk:
- Once you’ve entered Recovery Mode, you’ll see the macOS Utilities window. Select Disk Utility from the list of options and click Continue.
- In Disk Utility, you will see a list of drives on the left-hand side. Select your startup disk (usually named “Macintosh HD”) and click the Erase button in the top menu.
- You’ll be asked to choose the drive’s format and name. For the format, select APFS or Mac OS Extended (Journaled), and for the name, you can choose anything, but “Macintosh HD” is standard.
- Click ‘Erase’ to start the process.
- The erasing process may take a while, depending on your disk size. Wait for the drive to erase and click Done. Then, close the Disk Utility window.
Remember, erasing and reformatting your Mac will permanently delete all files, so make sure you’ve backed up anything you want to keep before starting this process.
7. Reinstall macOS
The next step is reinstalling macOS. Here are the steps to reinstall macOS using Recovery Mode:
- Connect your MacBook to the internet.
- Turn off your Mac and turn it back on while holding down the Command ⌘ + R keys on your keyboard. Keep holding the keys until the Apple logo appears.
- This will boot your Mac into the Recovery Mode. Once it loads, select Reinstall macOS and click Continue.
- Follow the on-screen instructions to select your startup disk and begin the reinstallation process.
- After the installation, your Mac will restart and display the Setup Assistant. Follow the on-screen instructions to set up your Mac.
- You should have a fresh macOS installation after completing the setup process.
This concludes the process to factory reset your MacBook or Mac.
