Attached is my setup. I plan to put in an additional 32gb of ram from OWC. I'm a little nervous to make the purchase because of this randomly rebooting problem with the latest OS X versions (see https://discussions.apple.com/thread/7525161?start=0&tstart=0). 1. What do you think of this setup? Will I be in the clear to edit and colour 4K footage well? 2. Is this randomly rebooting problem a widespread thing or does it only happen to a select few? Thanks!
