macOS Tahoe Incompatible with Mac Studio M3 Ultra (eclecticlight.co)

So much for buying a their most expensive model with a slower single core clock speed and slightly worse single core speed than their base model iPad Pro.

It seems surprising to me that this kind of basic thing (does the update work on the hardware we've released) wasn't validated by Apple prior to releasing this software update. Perhaps a sign of issues in the QA process at Apple around MacOS?

If that does not prove that Apple has been very hasty with this update overall, I don't know what does. The bar for quality control has been set kinda low.

actual title: "macOS 26.0 Tahoe build 25A354 is incompatible with Mac Studio M3 Ultra"

Title is misleading. Some Mac Studio M3 Ultra users are seeing upgrade failures, but others are not.

The source for this article is an Apple.com discussion forum thread with a couple dozen complaints so far.

Definitely an issue for some, but declaring it "incompatible" is misleading.

During the beta at least, inexperienced a ton of crashes

As someone who owns the M3 Ultra Studio, and has been on the iOS 26 Beta since day 1, I will keep this piece of trash off my machine as long as I can.

Brother Tim Cook's days are numbered.

A few months ago there was a seemingly similar crash in Sonoma 15.4, on some M1s [1], and AFAIR it was fixed in 15.4.1 ~2 weeks later.

Oh how I wish Arch or even Asahi supported the current generation of Mac hardware. Great hardware and memory architecture for inference, saddled with Tahoe.

Tahoe running fine on my M3 ultra. The only issue on the studio and the laptop was the initial sluggishness that I ended up attributing to the first spotlight indexing. Nothing new then.
