Key Takeaways
1. Users with M3 Ultra Mac Studios are experiencing installation issues with macOS 26 Tahoe.
2. The installation process fails at the final stages, reverting back to macOS Sequoia.
3. Other Apple products, like the M4 MacBook Pro, can install macOS 26 Tahoe without issues.
4. A potential cause for the problem may relate to the installer not recognizing the M3 Ultra’s Neural Engine.
5. Apple is aware of the issue and is working on a solution.
Despite its impressive capabilities, the M3 Ultra Mac Studio seems to have trouble with Apple’s newest operating system.
Reports from users are filling up Apple’s Community forums, indicating that Mac Studios powered by the M3 Ultra can’t seem to install macOS 26 Tahoe, which was launched on September 15. The original poster, Boschje79, mentioned that the installation proceeds without any issues until the final stages, where the Mac Studio defaults back to loading macOS Sequoia instead of Tahoe.
Users Share Their Frustrations
Many users resonated with Boschje79’s experience, stating they, too, faced obstacles in updating their M3 Ultra Mac Studios. The problem appears to be confined to this specific setup, as individuals using other Apple products (like the M4 MacBook Pro 14, currently listed on Amazon for $1499) were able to install Tahoe without any problems.
Another user, FilipOfficial, suggested that the installation failure might be linked to the installer not being able to recognize the M3 Ultra’s Neural Engine. The original thread included a panic message indicating that the installer couldn’t validate the Apple Neural Engine. At this time, it’s still unconfirmed whether this is the actual cause of the issue.
Apple Working on a Solution
Apple is aware of this issue and is actively pursuing a fix. However, for the moment, it appears that the most powerful desktop from Apple is stuck running slightly older software.
