Premiere Pro 25 NEEDS Sequoia OS for Mac
As a Mac Studio (M1 Max + 64 GB RAM) user, I've never had issues editing 4k clips. After I upgraded to Premiere Pro 25, at that moment the OS was Sonoma, and I was unable to edit any 4k clips. I cleared my cache, prioritized the RAM for Premiere, and rendered clips. Nothing would fix the issue. All my 4k clips lagged so much that I could not even scrub through a clip. Every clip would just show 1 frame and after 20 to 30 seconds would it catch up to the playhead after I stopped.
Solution:
I updated my OS to Sequoia and after the update, I uninstalled Premiere and re-installed it.
It seemed to fix the issue, and everything is playing normally.
