Up to date September 29, 2025: Apple launched the macOS Tahoe 26.0.1 replace. In accordance with the discharge notes, “This replace gives vital bug fixes, safety updates, and resolves a problem that prevented some customers from upgrading to macOS Tahoe on Mac Studio (M3 Extremely, 2025).” The article beneath was initially posted on September 17, 2025.
When Apple releases main updates to its working programs, we right here at Macworld often advise folks to carry off for a number of days earlier than putting in, simply in case. Although this time, following the discharge of macOS Tahoe final Monday, we didn’t really feel as cautious as we did prior to now, as a result of the betas have been actually steady. But it surely appears like we should always’ve heeded our previous recommendation.
The Apple Assist Neighborhood has a thread in regards to the M3 Extremely Mac Studio and customers who can’t set up macOS Tahoe. In lots of cases, customers run the set up and all the things appears to maneuver alongside properly, however when the Mac reboots (which is required when updating macOS), the system launches into macOS Sequoia, not Tahoe.
Ken Gruberman, who writes The Tech Daddy Substack, encountered this drawback when trying to put in Tahoe on his personal M3 Extremely Mac Studio. He informed me by way of e-mail that he spent the “higher half” of a day attempting to do the set up within the inside SSD, in addition to on an exterior drive.
Gruberman and the Apple Assist postings level out that the problematic Mac Studios had Sequoia 15.7 put in; Sequoia 15.7 was launched on Monday, together with Tahoe. Plainly throughout the set up, Tahoe is on the lookout for a driver however fails to seek out it, leading to a failed set up. Different posts within the thread state that different methods of performing an set up (akin to in Protected Mode or with an installer on an exterior USB drive) additionally failed.
A publish within the thread states that Apple Assist Europe is conscious of the issue and is engaged on a repair. Apple PR was contacted for remark and didn’t reply on the time of this posting.
If the difficulty is certainly tied to the Sequoia 15.7 replace, that might clarify the way it was not caught earlier than each updates had been launched. Apple usually follows up main releases with level updates to repair these points. M3 Extremely Mac Studio house owners who up to date to Sequoia 15.7 and haven’t up to date to Tahoe but ought to wait till such an replace is accessible. Customers who tried to do the set up however failed can take some solace in that the Mac reverts to Sequoia and continues to be usable.
