How to Factory Reset M1 Mac (MacBook Pro, Air, iMac, Mac mini)

First, a quick summary for the unfamiliar; A factory reset or a reset to factory settings involves erasing all the contents stored on your Mac – all files, data, and the OS itself – and restoring it to factory settings. If you’re switching from Windows, it’s similar to how you would perform a clean installation of Windows on a computer. Likewise, in this case, we’re basically just wiping the Mac and reinstalling macOS from scratch. This is essentially reformatting the Mac and then reinstalling MacOS, a process which is often necessary for users transferring ownership of a Mac, sending the computer in for repair, or for troubleshooting purposes.

It doesn’t really matter whether you own the new 13-inch MacBook Pro, MacBook Air, iMac, or Mac Mini, as the resetting to factory settings procedure remains identical on all M1 Macs.

How to Factory Reset M1 Mac to Wipe & Reinstall macOS

Before you go ahead with the steps mentioned below, make sure you back up the Mac and all the important files and data you want to keep as they will be permanently erased during the factory restoration. Without a backup, you will not be able to get those files back. Once everything’s complete, you’ll have nothing but the stock version of the operating system that shipped with your Mac, as if the Mac were brand new.

  1. Entering recovery mode is different on Apple silicon Macs. You need to shut down your Mac and then hold down the Touch ID/power button until you see “Loading startup options”. Now, choosing “Options” will take you to macOS Utilities. Here, select “Disk Utility” and click on “Continue” to get started.

That’s all you need to do to perform a factory reset. At this point, you just need to patiently wait for the installation process to complete which could take a while. After the factory reset, you’ll need to go through the initial set-up screen like it’s a brand new Mac.

Resolving the “No users available for authorization” Error Message when Installing MacOS

Some users may run into a “no users available for authorization” error message when trying to reinstall macOS on an Apple Silicon ARM Mac. This usually happens when only part of the hard disk was erased, and not the Data component. This is why you should choose to “Erase Volume Group” in the above instructions, if that is available.

One way to resolve this is to go back to Recovery Mode > Disk Utility, then select “Macintosh HD – Data” (or name of drive – Data), and click to Erase the Data portion. Quit Disk Utility and you will probably see a screen about activating the Mac, so go through that.

When complete, you can choose “Reinstall macOS” from the Utilities window within Recovery Mode.
