Jerky movement on MAC build

Hey guys, my target build is a mac and whilst my scene gets upwards of 200fps and locked at 120fps @ vBlank second, there is visible and jerky camera/mouse/player movement.

I tried removing onupdate/raycast scripts yet it didn't resolve anything. I tried a wide variety of graphic settings but the jerk is consistent.

On Windows it's silky smooth and vync caps perfectly at 60.

Any advice? I've been under the impression all these months my scene is an unoptimized piece of crap, when I decided to display an fps counter today I was shocked at how high it was.
