Apple has released two sets of instructions to perform an erase and restore on an Apple Silicon Mac or MacBook, roughly a week after users encountered issues performing a similar procedure intended for Intel-based Macs.

There are occasions where a Mac may not work properly, to the level that the Mac or MacBook won’t boot up at all, such as if a power cut is performed during an upgrade of macOS. Apple has procedures in place that can enable users to revive the firmware of the Mac, to allow it to boot and function normally.

However, over the last week, users who have needed to revive the new M1-equipped Mac mini, MacBook Air, and 13-inch MacBook Pro were encountering problems going through the same process, with Apple Configurator 2 throwing up errors in some situations.

Apple has now updated its instructions for dealing with a restoration of a Mac with separate details specifically for the M1 Macs. Like the Intel version, the Apple Silicon variant still requires Apple Configurator 2 installed on a secondary Mac, as well as supported USB-C and USB-A cables for charging and data transfer, and for users to configure their web proxy and firewall ports to allow all network traffic to work with Apple’s network.

The instructions largely break down to launching Apple Configurator 2 on the secondary Mac, connecting the two Macs together, restarting the non-functional Mac using a special key sequence, then using Configurator 2 to revive or restore the firmware and recoveryOS. Options are also available to erase the Mac completely and reinstall macOS from scratch.
