DFU or Die Trying
Perform DFU Restores on Apple Silicon Macs with Macvdmtool (2021)
Apple Mac rescue just got way easier—and commenters are absolutely giddy
TLDR: A new tool lets a working Apple Silicon Mac put a broken Mac into recovery mode with one command, replacing a famously awkward button-press routine. Commenters loved the simpler fix and roasted the old process as magical nonsense, while debating how different Apple’s newer Macs really are from Intel-era ones.
A niche Mac repair trick somehow turned into a full-on comment section mood swing after macvdmtool promised to save broken Macs without the usual finger-twisting ritual. The tool, built by Asahi Linux developer marcan, lets one working Apple Silicon Mac shove another troubled Mac into DFU mode—a special recovery state used to revive or fully restore it—using a simple Terminal command instead of the old button-mashing choreography from hell. You still need two Macs, the right cable, Apple’s software, and a little patience, but the crowd’s main reaction was basically: finally, a humane way to do this.
And yes, the biggest laugh came fast. One reader summed up the old process as having to press buttons in the right order while “hold your tongue at the right angle,” like some cursed Apple wizard ritual. That joke pretty much became the thread’s unofficial mascot. But there was also a mini nerd war bubbling underneath the relief: one commenter explained why Intel Macs can’t act as the host, saying Apple Silicon machines are more like iPhones or iPads under the hood, while Intel Macs are closer to regular PCs. Translation for normal humans: this slick recovery trick works because newer Macs are built more like Apple’s mobile gadgets than old-school computers.
So the vibe was equal parts repair-shop excitement, platform snobbery, and comedy. No giant flame war erupted, but the consensus was loud: Apple’s old recovery dance was ridiculous, and this tool makes rescuing a sick Mac feel less like black magic and more like an actual process.
Key Points
- •The article presents macvdmtool as a terminal-based way to place Apple Silicon Macs and Intel Macs with a T2 chip into DFU mode.
- •The host Mac must be a functional Apple Silicon machine; Intel Macs do not appear to be supported as hosts for macvdmtool.
- •The setup process requires Xcode command-line tools, Apple Configurator 2, and compiling macvdmtool from the AsahiLinux GitHub repository.
- •The host and target Macs must be connected with a data-capable USB-C or Thunderbolt cable using the correct DFU ports on each machine.
- •The article describes restoring an Apple Silicon target in DFU mode with cfgutil and an IPSW file, after which the Mac should reboot into Setup Assistant.
