A fresh change tucked away in the most recent macOS Sonoma beta could be a boon to Mac IT admins, as it should make it a little easier to get bricked Macs out of Device Firmware Update (DFU) mode.
Macs can get stuck in DFU mode for a handful of reasons, including when power fails during a software update installation. The problem is that once a Mac is stuck in that mode, it’s necessary to use a second Mac and Apple Configurator to get the machines going again.
In Sonoma, this is less of an issue because the relevant Configurator tools are now built into the Finder (though you will still need a second Mac to run the software).
USB-C cable still required
The good news is that connecting a second Mac to the bricked machine will no longer require you to download and install Configurator; you’ll only need a USB-C cable. Pop the cable into the rescue Mac and shut down the Mac you hope to bring back, then connect the cable to that second machine and follow the specific DFU instructions for your Mac, as detailed within this extensive Apple Support post.
