Just six days after releasing beta 5, Apple has released the sixth iteration of their current beta cycle, which includes iOS 9.3, OS X 10.11.4, and watchOS 2.2; however, this is the first time that Apple has left out a new tvOS build, which currently sits at beta 5.
Apple also seems to be dropping builds more frequently. While beta 5 was just six days ago, beta 4 was only eight days before that. Prior to beta 4, Apple held to a strict biweekly schedule.
iOS 9.3 and OS X 10.11.4 El Capitan public beta 6 is available today as well. Of course, there is no public beta for watchOS.
At the current time, there's nothing new in these builds. After all, it's the sixth iteration of a minor update. If you find anything new, let us know in the comments!
