Today, Apple has released the Fifth OS X El Capitan Beta to public beta testers. It has a build number of 15A262c. This comes just two weeks after seeding the fourth public beta. So far with this release, no major outside changes have seemingly been made. It is fairly likely that much of the improvements have been made internally as the official release of OS X El Capitan slowly creeps up on us, Fall 2015. You can install this update via the Mac App Store Update panel, just like the other versions of the betas.
