Apple tvOS 26.5 Beta 3 Public Update Rolls Out Without Major Changes

Apple has officially started providing the third public beta for tvOS 26.5 to public users. This release follows a familiar pattern as it refines its operating system ahead of a final launch. Users installing the software will not find any significant feature additions or visual overhauls this time around. Instead, the focus remains on performance improvements and bug fixes.



Alongside this release for the living room, the company also rolled out the third public beta of iOS 26.5 for users testing on mobile devices.



The latest test version focuses entirely on basic system stability



Those enrolled in the public testing program can download the new tvOS software directly through the settings app on their television hardware. Once the device reboots, it runs the newest build. Users should expect typical beta instability, though late-stage updates tend to operate more smoothly than initial drops.



The current update cycle extends to other device line-ups as well. In a parallel software push, the company rolled out watchOS 26.5 beta 3 without major changes for wearable owners. Just like the television platform, this update prioritizes background optimization over new capabilities to ensure everything functions properly.



Desktop users are seeing progress on their end, too. Today, the brand rolled out macOS Tahoe 26.5 public beta 2 update to the public as well.
