Apple’s most powerful desktop cannot install latest version of macOS – NotebookCheck.net News
Several users that own a Mac Studio with Apple’s M3 Ultra chip have reported that their desktop cannot install macOS 26 Tahoe, the latest version of macOS. This is apparently due to a bug that may relate to an inability to properly recognize the machine’s neural engine.
Despite all of its power, the M3 Ultra Mac Studio appears to be incompatible with Apple’s latest OS.
User reports are flooding into Apple’s Community forums stating that M3 Ultra-powered Mac Studios are unable to install macOS 26 Tahoe, which was released on September 15. The user that started this thread, Boschje79, states that the installation runs smoothly until the very end, at which point the Mac Studio simply loads macOS Sequoia instead of Tahoe.
Many other users commiserated with Boschje79, stating they also could not update their M3 Ultra Mac Studios. The issue seems to be limited to that particular configuration of that particular machine, as users with other Apple devices (such as the M4 MacBook Pro 14, curr. available on Amazon for $1499) were able to install Tahoe without incident.
A user by the name of FilipOfficial posted that the installation issue may be due to a failure of the installer to recognize the M3 Ultra’s Neural Engine. The original post included a panic message which stated that the installer cannot validate the Apple Neural Engine. As of press time, it has not been confirmed that this is the root issue.
Apple is aware of the problem and is currently working on a fix. As of now, though, it seems that Apple’s most powerful desktop is stuck on (slightly) outdated software.
