Installation Challenges for Mac Studio M3 Ultra
Upon the release of macOS Tahoe on September 15, 2025, users of various Mac models began updating their systems without significant issues. However, Mac Studio M3 Ultra owners encountered a persistent problem: the installation process would initiate, but upon reboot, the system would revert to the previous macOS Sequoia 15.7, leaving the update incomplete. This issue was widespread among M3 Ultra users, with multiple reports highlighting the same problem.

Technical Diagnosis
Investigations into the installation failure pointed to a hardware verification check related to the Apple Neural Engine (ANE). During the installation of macOS Tahoe, the system attempted to load a new driver for the ANE. However, a verification check failed, causing the installation to abort and the system to revert to the previous operating system. This issue was specific to the M3 Ultra configuration, as other Mac models did not experience similar problems.

Users shared their experiences on forums and support communities, detailing the steps they had taken to attempt the installation, including using Safe Mode, Recovery Mode, and external drives. Despite these efforts, the installation failure persisted, leading to growing frustration among users who had invested in the high-end Mac Studio M3 Ultra for its advanced capabilities.
