How to Erase Mac With Apple Silicon Before Returning It
If you plan on trading in your existing MacBook or selling it, then the one important step before you give away your machine is to factory reset it, so that all the data that you stored and used on the laptop gets erased and doesn’t fall into the wrong hands.
In this post, we’ll explain to you things you should know before you proceed to erase your M1 or M2 Mac, whether the process is the same as resetting an older MacBook, and how you can get it done without any issue. Let’s get started.
Why do you need to erase data before returning a Mac
You can factory reset your MacBook or any Mac device to safely erase all of the data inside of it before you move on to your next device. This way, you can be sure that your data doesn’t fall into the hands of the wrong person and isn’t misused by anyone else. Besides this, there are a bunch of reasons why you might want to erase data on your Mac:
- To reset user data before selling or trading in your Mac/MacBook
- To remove unwanted software that you otherwise can’t uninstall
- To make your Mac faster with a complete refresh
Is the erase and restore process the same as that on Intel-based Macs?
No. Unlike Intel-based Macs, Apple silicon Macs will require you to use a different method to access the macOS Recovery tool. In earlier Macs, you were able to get to the macOS Recovery screen by simply pressing and holding the Command (⌘) and R keys after powering ON your system.
Using the same set of keys on the new MacBook doesn’t bring up the macOS Recovery tool since Apple has changed the way you can access it on the new Macs powered by the M-series chips. The guide below will help you better understand how you may be able to erase and restore Macs with Apple silicon easily.
Supported Mac devices to use this Erase method
Ever since Apple released the first MacBook Air with its M1 chip in 2020, many other Macs have been powered by more versions of Apple Silicon in the years following. This list contains the names of all the supported Mac computers that are powered specifically by Apple M-series silicon and can be erased using the restore methods in this post:
- MacBook Air (M1, 2020)
- Mac mini (M1, 2020)
- MacBook Pro (13-inch, M1, 2020)
- iMac (24-inch, M1, 2021)
- MacBook Pro (14 and 16-inch, M1 Pro, 2021)
- MacBook Pro (14 and 16-inch, M1 Max, 2021)
- Mac Studio (M1 Ultra, 2022)
- MacBook Air (M2, 2022)
- MacBook Pro (13-inch, M2, 2022)
- MacBook Pro (14 and 16-inch, M2 Pro, 2023)
- Mac mini (M2 Pro, 2023)
- MacBook Pro (14 and 16-inch, M2 Max, 2023)
What should you do before erasing M1 or M2 Mac
Regardless of what you want to do with your Mac after erasing it, there are a few things you need to do on the Mac before you proceed to wipe its data and reinstall macOS on it. If this is the first time you’re attempting to erase a Mac, you must follow these steps to make sure your existing data on the Mac is secure and inaccessible to anyone other than you:
- Create a new backup of your Mac: This step is pretty self-explanatory. It’s important to back up everything you need to if you don’t wish to lose all of your data while switching between Macs. If you’re planning to give away your Mac, make sure you’ve backed up all of its existing data using the Time Machine utility and store the backup on an external hard disk. To back up your Mac, go to System Preferences > Time Machine > Select Backup Disk > [choose an external drive connected to Mac] > Use Drive.
- Sign out of your Apple account on FaceTime and Messages: When you erase your Mac, a fresh copy of macOS gets installed wiping every other data on it. To make sure you don’t run into issues later, it’s best to log out of your Apple account from all the services you used it with on your Mac like FaceTime and iMessage. To log off of FaceTime, go to FaceTime > Preferences > Settings > Apple ID > Sign Out. To log out of iMessage, go to Messages > Preferences > iMessage > Settings > Apple ID > Sign Out.
- Turn off Find My Mac: Before you can remove your Apple account from the Mac, you first need to turn off Find My on it. For this, go to System Preferences (Settings) > Apple ID > iCloud > Find My Mac > Options and click on Turn Off next to “Find My Mac”. This will make it easier to log out of your Apple account from the Mac entirely.
- Log out of your Apple ID on Mac: Once you’ve completed the above steps, you can now proceed to sign out of your Apple ID on the Mac to fully remove any trace of your iCloud data on the Mac. For this, go to System Preferences (Settings) > Apple ID > Sign out (on macOS Big Sur, this option will be visible inside the Overview tab on the left sidebar).
- Reset NVRAM: This step is necessary to clear your user settings from Mac’s memory and restore other security features. To reset the NVRAM on a Mac, turn off your Mac and power it on again. As soon as you power it, press and hold Option + Command + P + R for up to 20 seconds. This will reset the NVRAM and your Mac should show the setup assistant screen.
Once you’re done preparing your Mac for a factory reset, you can proceed to erase its contents by following any of the guides below based on your macOS version and preference.
How to erase Mac with Apple silicon without macOS Recovery
The easiest means to erase your Mac with an M1 or M2 chip is from the System Settings or System Preferences screen, which can be accessed when your Mac is currently powered on. This way, you can avoid going to macOS Recovery, which may take longer and require you to power off your Mac first. This method of erasing your Mac will be similar to how you factory reset an iPhone from its Settings app.
Depending on the macOS version you’re running on your Mac, the steps to erase it may differ. To check your current macOS version, click on the Apple logo on the Menu Bar (generally at the top left corner) and select About This Mac.
In the window that appears, you should be able to see the macOS version name at the top of the Overview screen.
Since this guide only works for macOS Ventura and macOS Monterey, you need to make sure you run either of these versions. If not, you should move on to the next section which involves going into the macOS Recovery mode.
On a Mac running macOS Ventura
Once you have verified that your Mac is currently running on macOS Ventura, you can easily start the erase process by opening the System Settings app on your Mac.
You can access this app from the Dock, Launchpad, or Spotlight or by going to Apple logo > System Settings.
Inside System Settings, click on the General tab from the left sidebar. On this screen, click on Transfer or Reset.
Here, select Erase All Contents and Settings.
You will now be prompted to enter your device or Apple ID password following which you can proceed to the next step by clicking on Unlock.
After you enter your device password, the erase assistant will show the Time Machine screen prompting you whether you wish to create a backup of your Mac to external storage. If you wish to create a new backup, click on Open Time Machine and follow the on-screen instructions to create a backup. If you’ve already taken a backup, you can click on Continue at the bottom right corner to skip this step.
You’ll now arrive at the Erase All Content & Settings screen, where you’ll see a list of data that gets wiped from your Mac during this process. To confirm your action, click on Continue at the bottom right corner.
In you haven’t already signed out of your Apple account, you’ll be prompted to enter your Apple ID password to remove this account from the Mac. Once you enter the account password, click on Continue to proceed.
When your Apple account is signed out of your Mac, you’ll see a final confirmation prompt on the screen. To go ahead and proceed with the reset, click on Erase All Content & Settings from this prompt.
Your Mac will now be reset and when the process completes, the device should reboot to the setup guide where you can connect your accessories and connect to a wireless network.
If you’re planning to give away your Mac, you don’t need to use the setup assistant at all and you can turn off your Mac by pressing and holding the Power button.
On a Mac running macOS Monterey
If your Mac is running on macOS Monterey, the steps to erase it is slightly different than the ones explained above. To erase your M1 or M2 Mac, open the System Preferences app on macOS from the Dock, Launchpad, or Spotlight. You can also access this app by going to Apple logo > System Preferences from the Menu Bar.
When the System Preferences window opens, click on the System Preferences tab from the Menu Bar at the top. In the dropdown menu that appears, select Erase All Contents and Settings.
You will now be prompted to enter your device or Apple ID password following which you can proceed to the next step by clicking on Unlock.
After you enter your device password, the erase assistant will show the Time Machine screen prompting you whether you wish to create a backup of your Mac to external storage. If you wish to create a new backup, click on Open Time Machine and follow the on-screen instructions to create a backup. If you’ve already taken a backup, you can click on Continue at the bottom right corner to skip this step.
You’ll now arrive at the Erase All Content & Settings screen where you’ll see a list of data that gets wiped from your Mac during this process. To confirm your action, click on Continue at the bottom right corner.
In can you haven’t already signed out of your Apple account, you’ll be prompted to enter your Apple ID password to remove this account from the Mac. Once you enter the account password, click on Continue to proceed.
When your Apple account is signed out of your Mac, you’ll see a final confirmation prompt on the screen. To go ahead and proceed with the reset, click on Erase All Content & Settings from this prompt.
Your Mac will now be reset and when the process completes, the device should reboot to the setup guide where you can connect your accessories and connect to a wireless network.
If you’re planning to give away your Mac, you don’t need to use the setup assistant at all and you can turn off your Mac by pressing and holding the Power button.
How to erase Mac with Apple silicon using macOS Recovery
You can use the following guide to erase your Mac if your device is running on an earlier version of macOS like macOS Big Sur or if you don’t prefer using System Settings/Preferences to erase your Mac on macOS Ventura and macOS Monterey. As long as you own a Mac with Apple’s M1 or M2 chip, you’re good to go with this method.
