Apple has released the first betas for OS X 10.11.6 and tvOS 9.2.2 to developers. The new OS X build is tagged as 15G7a while tvOS build is 13Y807. The new updates do not have any accompanying release notes so we can safely assume that they contain the usual ‘bug fixes and performance improvements’.
Just like with iOS 9.3.2 (which also got an iOS 9.3.3 beta update today), it was expected that OS X 10.11.5 and tvOS 9.2.1 would be the last updates before WWDC 2016 where the next major OS X and tvOS updates are expected to be announced.
If you were already on a previous OS X developer beta, just fire up Mac App Store and head on over to the updates tab to download and install it. Alternatively, you can download the complete 600MB update from Apple Developer Center.
To update your Apple TV to tvOS, you can either download the beta Restore Image and update via iTunes or use Apple Configurator to install the beta configuration profile to receive OTA updates. If you already had the configuration profile installed, check settings as you should be able to download and install the new build.
It goes without saying, do not try beta updates on your main devices as you could risk losing data.
We will update this post if we find anything new in these beta releases.
