Yesterday Apple released a new test version of OS X El Capitan 10.11 for Apple Beta Software Program participants. It was quickly removed from the air and so far no one knows exactly why most likely someone in Cupertino made the compilation available hastily.
Today, however, a new beta version has been released for developers. With her, Ma also made available yesterday's public version again.
The updates (OS X El Capitan Developer Beta 7, build 15A263e; and OS X El Capitan Public Beta 5, build 15A262e) are now available through the update system built into the Mac App Store, as long as you are using a previous trial version .
