This feature enables you to reset Mac without reinstalling macOS.

- Use a macOS bootable installer if you have created one before erasing your Mac and boot Mac from USB.
- Use the terminal to reinstall macOS if you are a specialist knowing how to do it correctly.
How to Factory Reset Bricked M1 Mac
Apple Configurator 2, a free macOS utility, is also a good solution to factory reset Mac mini M1 when you want to troubleshoot problems like:
- The Mac becomes unresponsive due to a power failure during a macOS upgrade
- You can't start the Mac from the startup volume or from the recovery macOS volume
To factory reset MacBook Air M1 and other Apple silicon Macs, you'll need:
- The second healthy Mac with the latest Apple Configurator 2 installed.
- 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.
- Keep the internet connection of the second Mac and power source all the way.
If you have all the requirements ready for machine resetting, let's get into the steps:
- 1. Connect the faulty 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 Mac into DFU Mode with these special key combinations, which show no screen activity from the problematic Mac.
For 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 a DFU icon appears in Apple Configurator 2 on the second Mac.
For Mac mini: Disconnect the Mac mini from power for 10 seconds, reconnect to power and immediately hold the power key when you see the status indicator light becomes amber.
For iMac: Disconnect the iMac from power, plug the USB-C cable into the Thunderbolt port closest to the stand, reconnect to power and immediately hold the power key for about 3 seconds.
Apple Configurator 2 allows you to both revive or restore an M1 Mac.
Revive Mac with Apple Configurator 2: It 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.
Restore Mac with Apple Configurator 2: This feature will restore the firmware, erase all data, and reinstall the latest version of macOS recovery and macOS on your internal hard drive.
So, depending on what depth you'd like to reset M1 MacBook Air/Pro/iMac/Mac mini, 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.
To revive a bricked M1 Mac
- 4. In Apple Configurator 2 from the second Mac, select the M1 Mac that won't turn on after the macOS update failure.
- 5. Right-click on your Mac device, and choose Advanced > Revive Device, then click Revive.
- 6. Wait for the process to complete.
- 7. The Apple logo will appear and disappear, and then your Mac will restart normally.
- 8. Make sure everything is working fine before quitting Apple Configurator 2 and unplugging cables.
To restore a bricked M1 Mac
- 4. In Apple Configurator 2 from the second Mac, select the first Mac computer.
- 5. Right-click on the Mac, choose Actions>Restore, and then click Restore.
- 6. Wait for the process of factory resetting to complete on your faulty Mac.
- 7. The Apple icon will show and disappear, and then follow with an auto reboot.
It will take about 20-30 minutes to download macOS Monterey and install it on the Mac. When it finishes, you'll see the factory setup screen. And then you can quit Apple Configurator 2 and unplug any adapters and cables.
The Bottom Line
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 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 is reported by some users. Because resetting your Mac cannot resurrect the dying device caused by excessive SSD usage.
