Exactly one week after the fifth, Apple today released the sixth beta version of OS X El Capitan 10.11 for developers.

The compilation 15A244d is available both through the update system built into the Macs (within the Mac App Store) and through the developer portal and brings bug fixes / general improvements; there are still several known errors. Should any relevant news arise, we will disclose it here.
Along with OS X El Capitan beta 6, Apple also released the Apple Configurator 2.0 beta 5. Interestingly, this is the second time in a row that the company releases updates only for OS X, leaving iOS 9 and watchOS 2 aside.
