Frozen Mac? How to recover it using DFU mode

– Source: Apple Support. Experimenting can sometimes lead to issues. That’s exactly what happened to me after a failed macOS installation, which resulted in a big question mark with a prompt to visit the Mac restore page. For some years now, when a Mac is unable to boot macOS and cannot even run macOS Recovery to repair or reinstall the OS, the only way to bring it back to life is to enable DFU Mode (Device Firmware Upgrade). This mode is stored in ROM and cannot be erased under any circumstances.1
Mac Studio!

Mac Studio!

And here it is, the Mac Studio. I had to go through a long bureaucratic process to get it, but I finally managed, and now it’s right here in front of me. The first thing you notice is that the box is heavy, very heavy. The specs state that the Mac Studio is large and weighs about as much as three Mac Minis stacked on top of each other (19.7 x 19.7 x 9.5 cm^3 and 3.6 kg for the Mac Studio versus 19.7 x 19.7 x 3.6 cm^3 and 1.2 kg for the Mac Mini). I’ve never held three Mac Minis together, but the box gives a strong impression of solidity, which is definitely a positive for such an expensive device.
