1) Grandma is prompted to update to Sonoma, and so she does.
2) But note that the installer does not update the recovery partition.
3) Laptop reboots, and grandma sees an Apple logo for exactly 2 seconds, and then the screen goes black. Manually rebooting results in the same thing, every time.
4) Grandma now tries to roll up her sleeves and see if she can fix it. She googles around, and discovers that the she should be able to get into the Recovery OS and maybe fix things there... but when she tries to do that, same thing: apple logo for 2 seconds and then black screen.
How did I come up with this play-by-play? Well, because today I was said grandma.
Where does this involve the average user going back in versions of their on volition? That's the whole point of why this bug is horrible: you get no say in the matter. You upgrade to Sonoma, and depending on your refresh rate, you can't boot into your OS. Wanna use the Recovery OS? Too bad: that's too old to know to use a functioning refresh rate settings (because the installer left the old Recovery OS version in place), and instead it uses whatever was set in NVRAM (or similar) from when you last configured the refresh rate.
Wasted today using another MacBook to update the Recovery OS via DFU (using Apple Configurator), and now I'm reinstalling Sonoma from that recovery, and praying that this will unbrick my laptop for work tomorrow.
