2nd Betas of MacOS Tahoe 26.6 & iOS 26.6 Available for Testing

While most beta users, and likely Apple too, are focused on the MacOS Golden Gate 27 betas and iOS 27 betas, a separate beta channel remains for current versions of Apple system software, and those have been updated today. With the second beta version of MacOS Tahoe 26.6 beta, iOS 26.6 beta, and iPadOS 26.6 beta, being released for developers, there are now two separate beta tracks going for developers to follow.

Interestingly, some RC builds of betas for MacOS Sequoia 15.7.8 and MacOS Sonoma 14.8.8 were also made available, suggesting perhaps that MacOS Tahoe 26.6 and iOS 26.6 might be finalized sooner than later, despite being only in their second beta release.

Again, these are new betas for MacOS 26 and iOS 26, NOT the just released betas for MacOS 27 and iOS 27. If you already installed MacOS 27 beta, iPadOS 27 beta, or iOS 27 beta, you will not find beta builds available for OS 26.6.

How to Download iOS 26.6 Beta 2 / iPadOS 26.6 Beta 2

For iPhone and iPad:

1. Open the “Settings” app
2. Go to “General” and then “Software Update”
3. Download and install the latest iOS 26.6 beta 2 / iPadOS 26.6 beta 2

How to Download MacOS Tahoe 26.6 Beta 2

For Mac:

1. From the  Apple menu go to “System Settings”
2. Go to “General” and then choose “Software Update”
3. Select to update to MacOS Tahoe 26.6 beta 2

Don’t expect any new features or major changes in these updates, and they likely include bug fixes (hopefully one to resolve the known issue with trying to make a MacOS Golden Gate virtual machine failing) and security patches only. Any major new features or changes are almost certainly being directed into efforts for MacOS 27 Golden Gate beta and iOS 27 beta.

Apple usually releases multiple beta versions before issuing a final release to the general public.
