You can download IPSW files using a tool like Mist or from the table on Mr. Apple’s USB-C to USB-C charging cable works perfectly for this.īefore starting make sure you have Configurator installed on your host Mac and optionally pre-download the IPSW file for the macOS version you want to install on the target Mac. You also want to make sure you are using a USB-C and not a Thunderbolt cable. Make sure you have read Apple’s documentation on the process before proceeding, as which USB port to use on the target Mac is critical. Their post was in turn a refinement of steps originally posted by Timothy Perfitt on Twitter a few months earlier. I first saw these steps when a colleague shared them on the MacAdmins Slack in summer 2021. I can’t take any credit for developing this method, again I just want to spread the word.

This method isn’t new but I frequently come across users who struggle to initiate a DFU so I want to help spread the word further. Thankfully there is an easier method I’ve been using with near 100% success for the past year and a half. Unfortunately Apple’s official documentation to Revive or restore a Mac with Apple silicon using Apple Configurator has always given users trouble. Using DFU mode and Apple Configurator is the fastest way to erase and perform a clean installation of macOS on an Apple Silicon Mac.
