Apple Metal Mercury GPU not working after MacOS Sierra 10.12.2 update - video preview and export corrupt bad
Bought a new Mac with Sierra installed. Installed Premiere Pro CC 2017 and it worked. Then the update 10.12.2 update came December 13, 2016. It downloaded but I did not install update until this week. The moment I installed, my video previews, playback, and export did not work when using Metal for GPU Acceleration. Videos looked like multiple frames and the image was cut in half with green and red pixels or black and white sometimes. The good news is Open CL takes care of this problem, but the bad news is Metal is not being used for acceleration. I thought the new update for Premiere Adobe pushed today would have fixed it but no. I have deleted video previews, cleaned the media cache, re-installed Premiere Pro CC 2017 and even tried older versions back to 2015.3. I talked to Apple and they suggested using time machine or internet recovery to get my system back to a stable version of OS to work with Premiere, but this computer is too new and even wiping the drive and re-installing may OS does not fix this problem. I have this issue on both my editing computers now, but luckily my older Mac Pro came with El Capitan, so I can use that for more intense projects.
I want to get Metal Acceleration working again, Adobe, are you looking into this error to fix in a future update? Will Premiere Pro support Metal GPU in Sierra going forward?
