Following the media event Apple has now releases the GM build of OS X El Capitan to developers. This comes a little over a week after the last version. There aren’t a ton of changes in this beta. That’s because this is what the public will see when it comes out. Speaking of that, we’re going to be seeing OS X El Capitan make a free public launch the September 30.
This beta can be downloaded by developers in the Mac App Store > Updates > Software updates > OS X El Capitan GM.
