Apple has released macOS Tahoe 26.0.1, a minor update for Mac users, which focuses on fixing a critical bug that affected systems running on the M3 Ultra chip. This is the first point update since the major release of macOS Tahoe earlier this month.
The update specifically addresses performance instability and application crashes that some M3 Ultra Mac Studio and Mac Pro users had reported. While the M3 Ultra delivers Apple’s most powerful desktop performance yet, a bug in macOS Tahoe caused unexpected slowdowns and reliability issues when handling demanding workloads. This update aims to stabilize those systems and restore expected performance levels.
Apple describes macOS 26.0.1 as a targeted maintenance release rather than a feature update. No new functionality is included, but resolving the M3 Ultra issue was a priority given how disruptive it had been for professionals using these high-end machines.
Here are the complete release notes from Apple:
This update provides important bug fixes, security updates, and resolves an issue that prevented some users from upgrading to macOS Tahoe on Mac Studio (M3 Ultra, 2025).
For Mac users who are not on M3 Ultra hardware, the update still appears in Software Update and is recommended for installation, as it may also include under-the-hood security fixes and optimizations not publicly detailed by Apple. As with most minor macOS releases, installation can be done through System Settings > General > Software Update.
macOS Tahoe 26 has already introduced significant new features such as Liquid Glass design, enhanced Apple Intelligence capabilities, and improvements to system apps like Safari, Messages, Reminders, and more. This 26.0.1 release marks the first stability-focused refinement, underscoring Apple’s approach of quickly addressing early post-launch bugs before pushing forward with feature updates like macOS 26.1, which is currently in beta testing.
Users of M3 Ultra Macs should see immediate benefits from this update, but it is advisable for all macOS Tahoe users to install it to ensure overall system security and stability.
