Mac Pro 5,1 Quicktime Player 4K Stutter
I may cry the day the'ol Mac Pro truly becomes obsolete. It's been such a great machine!
Purchasing a Phantom 4 Pro drone has lead me into the world of 4K. When exporting a 4K project from Final Cut Pro X 10.4 the playback stutters in Quicktime Player. I thought my Mac hardware was prepared for handling 4K, but maybe not?
Someone on this forum suggested an alternative playback app called IINA, which I tried, and it played the stuttering footage flawlessly. I'm grateful for the tip but still wondering why Quicktime won't play it nicely? Anyone happen to know? I also tried playing the stuttering file on my Early 2013 MacBook Pro using Quicktime Player (not IINA) and it played fine?

Thanks... and PS: I attempted to upload an example clip but the video-uploading icon was grayed-out.
