Apple has released macOS Tahoe 26.0.1. You get bug fixes, security updates, and one important fix for Mac Studio owners with the M3 Ultra chip. Update now through System Settings > General > Software Update.
What’s fixed for Mac Studio M3 Ultra
If you use a Mac Studio with M3 Ultra, you likely saw the Tahoe 26.0 installer fail at the end and roll you back to Sequoia. Apple says 26.0.1 resolves that problem. The original failure stemmed from a hardware check during install. You should be able to upgrade normally after installing today’s build.

New to this issue? Reports last week pointed to the installer aborting when a component tied to the Neural Engine failed validation. That aligns with Apple’s brief note about a failed hardware check in the original 26.0 installer.
How to install without headaches
Do this before you hit Update:
- Back up your Mac with Time Machine or your backup tool of choice.
- Free up a few extra gigabytes to give the installer room to work.
- Plug in power and keep a stable internet connection.
- Open System Settings > General > Software Update and install macOS 26.0.1.
Why this .0.1 landed so fast
Tahoe 26.0 shipped on September 15, 2025. Two weeks later, Apple is pushing the first stability release. That cadence tracks with prior macOS cycles, where early point releases clean up issues missed during the beta window. Expect further refinements as Apple hardens the new design and core frameworks introduced with 26.0.
What else Apple updated today
Apple also rolled out iOS 26.0.1, plus smaller updates across watchOS, tvOS, visionOS, and HomePod software. If you keep multiple Apple devices, update those too to stay in sync on security fixes and compatibility.
Release notes, at a glance
Apple’s macOS 26.0.1 note is short:
- Important bug fixes and security updates.
- Fix for users who could not upgrade Mac Studio (M3 Ultra, 2025) to macOS Tahoe.
For security specifics, Apple lists CVEs and technical detail on its security pages once documentation is ready. Check that index after you update.
Install macOS 26.0.1 today, especially if your Mac Studio M3 Ultra refused to take Tahoe 26.0. This build clears the installer roadblock and continues the usual early-cycle stability work.
I decided to wait on 26.0.0 – figured something this big and new I should wait for 26.0.1 – now I’m
going to wait much longer. I don’t care about Glass and other “pretty” features. I have scientific apps that must work after I upgrade. I’m also waiting for new versions of those apps. I’ve been thru OS upgrades before with Apple, they have been fine. But, this one stands out as something to be cautious about.
my studio loaded tahoe but now its not right in issues with the dock but most important it wont allow me to enter password to load 26.1 any thoughts
Seems to break video connection to my Anker 8 in 1 hub. Buggy with an Apple Multiport Adaptor
In other words, Apple is too incompetent to release a new OS that isn’t broken and makes us all unprepared Beta testers. Same old Apple FUBAR reality
Yes, because no other OS in history ever needed a bug fix. Only Apple is that ‘incompetent’.
Lately MS delayed release of 25H2, due unstability issues. Tim Cook plans fixed events every September and despite the OS is ready or not they release it. OS 26 Glass features are complex and maybe beta tests were not ready yet. On top of it OS 26 is slow compared to predecessor. So definitelly we will get next updates soon.
Windows/Linux – Made to work on unknowable number of devices and components.
Apple – Builds all the hardware and the OS
Big difference.
