This is a serious issue, especially for newer professionals like my self who are working in video. The compatibility with Mac is unacceptable at many times.
I have seen a large number of creators moving toward Final Cut Pro (see youtube blogs) and i am starting to see why.
Amongst the several problems i face every day with Premiere while doing average tasks.
example: I am currently writing this while i have a short 1080p (1920 x1080) clip in my project, on a completely reset and clean MacBook pro. It is an arduous effort to have the clip play back at (1/4) while i scroll through times in the clip to see what i am looking at.
Now, a 1080p played back at 1/4 is very very basic in the industry, and using premiere is making this a chore and challenge for my editing workflow.
I have called Adobe in the past, I have called Apple in the past. To optimise my system so i can edit at an appropriate speed.
But I am still having problems !
