Support has been disabled for El Capitan’s new full-screen mode, as it was causing issues with some of Lr’s modal dialogs (such as Export, etc). Lightroom features its own full-screen & full-screen preview modes, so the application continues to behave the same way it always has with prior versions of Mac OS. That said, we will continue to investigate ways to accommodate changes to Mac OS workflow going forward.
The OS's built-in fullscreen app handling includes advantages that go far beyond an application simply filling the screen from corner to corner. With this upgrade, LR has jettisoned all of those advantages, and is now forcing its users to interact with the program in ways that apply to no other application out there.
Thanks so much for your consideration.
The Maximize button of LR in MAC EL Capitan is not taking the application to Full screen mode with Menu Bar mode without the DOCK. Though there is a workaround to get there but I would prefer to have that functionality back. Looks like Adobe has made this change in there latest update. Please revert it back.
I would love to run Lightroom (and any other Adobe App) in OS X's built in SplitScreen mode. Apparently Adobe don't use Apple's fullscreen APIs so it's not currently possible, but it would make my working life easier/more enjoyable.
