Come on, man. :/

How are Apple machines the least functional of all the devices I've ever had to use. What the hell is going on.

"I'm gonna try to use this as my daily driver!"

Apple M1: "Hehe, no you're not!"

In very rare circumstances, such as when a power failure interrupts macOS installation, your Mac might start up to a circled exclamation point. This means that the firmware stored in your computer's memory needs to be revived or restored.

Well, here we go.

I NEED A SECOND MAC TO RESTORE THE FIRST ONE WHEN SHIT GETS THIS BAD?

Bro come ON.

@thephd nope, a linux machine also works with idevicerestore

thephd OP , vor 6 Tagen

@Sobex Given my current luck, do you think it would be good to do this, or do you think I should just go to the Apple store?

@thephd @Sobex It can't make anything worse so you might as well try it! Fedora should have usable packages (you might need to select an older macOS version to restore since I think the latest builds triggered some issues that just got fixed but not released yet).

Can you still get into recoveryOS though? If you can then it should be fixable without DFU... (DM me if you want me to help troubleshoot ^^)

@lina @thephd I will second Asahi Lina advice, she and marcan@treehouse.systems know a lot more than me about macOS boot process and fixing macOS.

thephd OP , vor 5 Tagen

@Sobex @lina Alas, I am screwed in this regard (it won't boot into RecoveryOS anymore, I think it broke) and I always get put on the exclamation point. I don't have Linux machine but I can pribably make a liveusb with idevicerestore on it or something....?

@thephd @lina This will not work because Apple Silicon does not boot off USB. You always boot the kernel from a container on the internal drive. The kernel can then do other things like load the remainder of the system from a USB drive, but if you've hosed the Boot process, you won't boot from USB either.

If you don't have any other computer lying around, idevicerestore can't do anything for you.

@thephd @lina At least your mac has a screen to display the exclamation mark. Mac Minis and Mac Studios do not have this luxury and may resort to flashing a Morse SOS as the only way to tell that the boot loader is hosed and they need to be revived by another device.

@Sobex @thephd They actually used to support displaying that over HDMI... but Apple removed it in an update early on for some reason. Maybe they didn't like that it only worked over HDMI and not over Thunderbolt/Type C?

@lina @thephd In the past I think there used to be a crashing startup chime / sad mac start-up chime, has this vanished too ?

lina , vor 4 Tagen

@Sobex @thephd I don't think Apple Silicon ever had that ^^;;

@thephd does it not even boot into internet recovery? That's capable of fixing almost everything in my experience, if you haven't tried that specifically.

If you can't even get into that... yep. Box. It's super annoying that they can't just use a USB drive to bootstrap it. It has bitten me once before.

@groxx @thephd Internet recovery isn't a thing on Apple Silicon ^^

The System recoveryOS is stored on NVMe, so if that fails to boot you need DFU like an iPhone.

@lina @thephd well crap. that seems... a bit short-sighted :/

no doubt there's some reasonable(ish) security reason for it, but the rest of us get pushed closer to disaster.
