Apple has released macOS Tahoe 26.5 developer beta 4, arriving just one week after beta 3 as the company prepares for the update’s public rollout in the coming weeks. The new build, 25F5068a, appears to be another small pre-WWDC release focused largely on system refinements rather than headline features.
With macOS 27 expected to debut at WWDC in June, this update is shaping up as a stability-focused release for developers testing ahead of Apple’s next major software cycle. Unlike macOS 26.4, which brought back Safari’s compact tab bar and added features like Charge Limit controls, macOS 26.5 remains relatively quiet so far.
Apple’s broader 26.5 software cycle includes cross-platform additions such as progress on end-to-end encrypted RCS messaging, Live Activities support for third-party accessories in Europe, and Suggested Places improvements in Maps, but Mac-specific changes still appear minimal. Right now, bug fixes, security patches, and performance improvements seem to be the main focus.
How to install macOS 26.5 developer beta 4
- Back up your Mac before installing
- Open System Settings
- Go to General > Software Update
- Click the “i” icon next to Beta Updates
- Select macOS Developer Tahoe Beta from the dropdown
- Click Done and begin installation
All the changes so far
At this stage, macOS 26.5 beta 4 does not introduce any major visible features. Apple appears to be using this cycle to improve overall reliability, polish existing features, and prepare macOS Tahoe for its final release before shifting focus to macOS 27. That makes this beta especially important for developers testing app compatibility, even if everyday users may notice few immediate differences.
