Apple has recently launched the fourth beta versions of its next-generation operating systems: macOS Tahoe 26.1, iOS 26.1, and iPadOS 26.1 Beta 4. The official release of these updates is anticipated by the end of this year, marking a significant milestone in their development.
The beta testing phase has now been in effect for four weeks, with a shift to a rapid release cycle following the previous beta launch. Users can now download the latest pre-release versions, and Apple is actively encouraging feedback to identify any bugs or areas needing refinement.
Key enhancements in these operating systems include improvements related to Liquid Glass technology, a more cohesive display experience, and upgraded background security features that build on previous rapid security updates. Apple is also working to improve the pairing process for third-party smartwatches. A noteworthy update in iPadOS is the return of the "Slide Over" feature, albeit with some modifications. Additionally, while the hard drive icon has received a redesign, issues with perspective display may still persist.
Apple plans to integrate advanced AI solutions from third-party providers, with ChatGPT being among the supported applications. Users will also find an intriguing option to significantly reduce the Liquid Glass effects, which will be detailed in a future post.
Developers can now access these latest pre-release versions, which are nearly complete, as indicated by version numbers approaching "a". The macOS 26.1 Beta 4 has a build number of 25B5072a and was released on October 20, 2025. The iOS and iPadOS versions share the same build date of October 20, 2025, with iOS having a build number of 23B5073a. Other updates released in their fourth beta versions include watchOS 26.1 Beta 4, tvOS 26.1 Beta 4, and visionOS 26.1 Beta 4, each with distinct build numbers.
