As WWDC26 is right around the corner, macOS Tahoe 26 is entering what is known as "Bug Fix Mode" or "Maintenance Mode" where only bug fixes and security updates will be released for the software. Instead of doing a post for every single build that comes out, I decided to consolidate them into one post since most beta testers will be on macOS 27, but I wanted to continue to show love for macOS Tahoe 26.

Remaining Issues
Untested Issues
- When filling your screen with the App Store, the title of the View may be wider than expected
- On non notched devices, the volume indicator may have excessive padding in full screen (Present since 26.2 Beta 3)
- Alarms may not play when your display is asleep for a long period of time (FB10086690)

- Issue present since macOS 13.0
Additional Notes
- Updates might not show up in Settings as soon as it releases if you have Rosetta 2 installed. This is due to Apple not releasing Rosetta at the same time as macOS Tahoe Betas. Please wait up to an hour before you will be able to update.
- If you are encountering a memory management issue (eg. a Memory Leak), please provide what app/process it is coming from (Using Activity Monitor) and what you were doing in that app.
- macOS 26 Tahoe will be installed via a Delta Update in System Settings. Please be aware about this, as the update won’t install with an installer.
