Just wanted to say for anyone else that views this thread because of the Lumetri color issue; Cody’s solution works. Basically when you install new Looks or LUTS in Premiere on Mac, it only installs it for Premiere. You need to copy for files over to Media Encoders Application Folder.
To Access it, go to Applications>Adobe Media Encoder CC 2015>Adobe Media Encoder CC 2015.app. Right Click on the app and choose Show Package Contents. Then you’ll be able to find the Lumetri folder and follow Cody’s instructions. Do this same action to find the Lumetri Folder for Premiere Pro.
Hope this helps anyone else that runs into this issue.
