Summary: Here is a comprehensive guide to help you reset an M1 Mac to factory settings, including resetting a bootable M1 Mac and a bricked M1 Mac.
For some reason, you may want to reset your new Apple silicon Mac.

No matter what is the reason you want to reset M1 Mac to factory settings, there is one thing you need to pay attention to. You are not recommended to directly erase the startup disk in Disk Utility though you can do it most of the time and reinstall macOS as you did on the Intel-based Mac.
Resetting M1 Mac is based on if the Mac is bootable and if you want to keep the data on the computer, here is the complete tutorial.
Guide to reset a bootable M1 Mac to factory settings
Since your File Vault is on and you can't erase the startup disk directly with Disk Utility on the M1 Mac, you need another way to get your Mac prepared, i.e., get existing data cleared.
- 1. Restart your Mac and continue holding the power button until you see the startup options window.
- 2. Select Options and then continue with the required administrator password. If you can't boot to regular macOS Recovery Mode, use Fallback Recovery OS.
- 3. When you see a list of recovery utilities, click Utilities from the top menu and select Terminal from the drop-down menu.
- 4. Type resetpassword in Terminal, then press Return.
- 5. Click the Reset Password window, choose Recovery Assistant, and then click Erase Mac.
- 6. Click Erase to confirm your operation and then your M1 Mac will restart automatically.
- 7. After setting the language and click macOS Utilities if it reminds you that the version of macOS on the selected disk needs to be reinstalled.
- 8. Make sure the M1 Mac has internet connection during activating the Mac.
- 9. Click Exit to Recovery Utilities when it's completed.
- 10. Repeat the operation from step 3 to step 9 one more time.
Then you are safe to go with macOS reinstallation using one of these methods.
- Use the Reinstall macOS Big Sur utility in macOS Recovery Mode if your Mac was running macOS Big Sur 11.0.1 before you erased the Mac.
- Use a macOS Big Sur bootable installer if you have created one before erasing your Mac and boot Mac from USB.
- Use terminal if you are a specialist knowing how to do it correctly.
Note: You can also use Apple Configurator 2 to reset the M1 Mac if the way above is not working.
Guide to Factory Reset a Bricked M1 Mac
Sometimes, factory resetting is a good solution to fix causes that stop your M1 Mac from booting up as well.
Exactly, you can reset your Mac with an macOS software called Apple Configurator 2 when:
- 1. The Mac becomes unresponsive due to a power failure during a macOS upgrade
- 2. You can’t start the Mac from the startup volume or from the recovery macOS volume
To reset your Mac mini (M1, 2020), MacBook Pro (13-inch, M1, 2020), and MacBook Air (M1, 2020), prepare the following things first:
- The second Mac (runs macOS Catalina or later, has latest Apple Configurator 2 installed, and has network connection)
- A USB-C to USB-C cable for newer Macs or USB-A to USB-C cable for older ones, which supports power and data.
If you have all the requirements ready for machine resetting, let's get into the steps:
Note: Keep the second Mac connected to the network and power source all the way.
- 1. Connect the M1 Mac via the USB-C port with the second Mac using the cable you prepared.
- 2. Launch Apple Configurator 2 on the second Mac.
- 3. Boot your M1 Mac into DFU Mode with these special key combinations, which shows no screen activity on the M1 Mac.
- For M1 Mac mini: Disconnect the Mac mini from power for 10 seconds, reconnect to power and immediately hold the power button when you see the status indicator light becomes amber.
- For M1 MacBook Air and MacBook Pro: Press and hold the power button, then simultaneously hold Control + Option + Shift for 10 seconds. And then keep holding the power button until the notebook appears in Apple Configurator 2.
Apple Configurator 2 allows you to both revive or restore an M1 Mac.
A revive will update the firmware and recovery macOS to the latest version, which won't make any changes to the startup volume, the user’s data volume, or any other volumes.
However, the restore feature will restore the firmware, erase all data, and reinstall the latest version of recovery macOS and macOS on your internal hard drive.
So, depending on what depth you'd like to reset your M1 Mac, either keep or erase the previous data, you can continue with different guides in Apple Configurator 2.
Note: If you lose power to either Mac during this process, you need to do the revive or restore operations once again.

Factory resetting is the easiest way to start afresh on your M1 Mac. It helps when you can’t start this Mac for startup disk corruption, firmware issues, or failed macOS update. It's also the most efficient way to erase personal data before you decide to donate or exchange your M1 Mac.
But you need to keep in your mind that backing up your data before resetting the Mac in case you want it back someday. Besides, try to prevent excessive SSD wear of your M1 Mac that reported by some users. Because resetting your M1 Mac cannot resurrect the dying M1 Mac caused by excessive SSD usage.
