Developers can download the ‌macOS Tahoe‌ 26.5 update by opening up the System Settings app, selecting the General category, and then choosing Software Update. Beta Updates will need to be enabled, and a free developer account is required.

No new features were found in the first three ‌macOS Tahoe‌ 26.5 betas, and it's likely the update primarily focuses on bug fixes and performance improvements.

Update 1:05 pm: The update is now also available to public beta testers.

Unfortunately, I think Apple's dedicating too much time to pushing out new shiny features in general, and not enough time in fixing bugs. macOS 15.7.5 is having so many issues with Bluetooth, audio, Safari, and overall performance, that I'm going to have to wipe and downgrade to 15.4 if they don't have it resolved in the next month.

Why, when Apple releases a new OS, do they need to fix things that were already working fine?

For example, if Bluetooth issues were fixed in macOS Sequoia, why are they broken again in macOS Tahoe?

You get my point? it feels like releasing a new OS is like breaking everything that was already fixed. I don’t get it.

I cant believe they are sticking with an all white interface, its blinding and unless you have apple monitors the contrast of ui elements is low. The OS already looked better in its past when improvements were for usability and not hey I like glass lets put that everywhere.
