macOS 26.0.1
Juli Clover (no release notes, no security, no enterprise, no developer, full installer, IPSW):
According to Apple’s release notes, macOS Tahoe 26.0.1 addresses a bug that was preventing Mac Studio machines with an M3 Ultra chip from being upgraded to macOS Tahoe. A failed hardware check was causing macOS Tahoe installation attempts to be aborted, with Mac Studio users ultimately stuck on macOS Sequoia.

Update (2025-09-30): Laurent Giroud:
This is just incredible. That this bug had to be fixed in a new release means they never tested it on that Ultra configuration.
That or they knew it prevented installation and chose to kept users of that setup to bang their heads against the wall when trying to upgrade.
Today’s update to macOS Tahoe (26.0.1) resolves an issue in apps where AutoFill for Mac apps could make apps slow down over time due to improper handling of event taps, causing them to accumulate over time. People particularly noticed this in Chromium-based web browsers and Electron apps. If your app or framework decided to work around this issue by using an internal AppKit defaults key to turn off AutoFill, I recommend you re-test on macOS 26.0.1, then limit that workaround only to macOS 26.0.0, and remove it for macOS 26.0.1 and above.

This and the Electron bug, I think it's time to give up on Apple. They *really* don't care. Like, to a malicious degree. Like a slap in the face. I can't believe how bad they've gotten. We should all invest our energy into making Linux as good as Mac OS X used to be
This is crazy. I’m trying to imagine what kind of testing procedure would exclude testing on one of Apple’s own new chips for the entire life cycle thus far, up to and including release. They only have a few computers and chips. If they didn’t test on the M3 Ultra, what DID they test on?
This is a very basic QA thing. We’re not talking about testing on Intel Macs here. This is a chip many people could plausibly be actively using right now. And if you have it you’re almost certainly a professional meaning it should have received extra priority in my opinion but maybe I’m wrong.
@What Yeah, it’s not some obscure configuration. It’s the current top-of-the-line Mac (since the Mac Pro still has the M2…).
