Apple announced the next version of OS X yesterday at its Worldwide Developers Conference. The next version of the OS will be called El Capitan and it'll be available sometime in the fall.
Of note for photographers in the update will be the inclusion of Apple's Metal framework which will greatly improve graphics performance, as much as 40x more efficient when rendering than OpenGL. Keep in mind this is just a raw number, and we're not going to see a 40x boost in performance across the board.
According to PetaPixel, Adobe has said that they've seen an 8x improvement in rendering for After Effects, which sounds very promising. It's unknown at the moment how much improvement we'll see from Photoshop or Lightroom, but we do know that Adobe will support Metal in all of its CC applications this fall.
