Today, Apple has seeded developers with the first OS X El Capitan 10.11.4 beta. Devs can download the build by going to the Developer Center. There’s no word yet on whether it’s available for public beta testers.
Update: The beta is now available to public beta testers via the Mac App Store.
Interestingly enough, OS X 10.11.3 is still in beta, so right now, Apple has two different beta builds available for testing. They made the same move with iOS 9.3, which was launched in beta today as well.
When changes are found, we’ll update this post. It’s likely that there are changes made, since iOS 9.3 has brought quite a lot of tweaks and updates so far.
Let us know if you notice anything different in the new OS X build!
