I think you're overselling it, the minimise? Sure.
But I can't think of a single animation that added a delay to processing on MacOS.
Compare to say, Windows, at least.
Switching desktops on MacOS is a >1 second long animation that blocks input which can't be disabled. It can only be replaced with a fade in/out which is just as long.
Try Liquid Glass on iphone. Absolutely horrible if you don’t turn off all the motion.
