Just a PSA for anyone still around, but I've had occasion to fire up the game on macOS Big Sur (latest release) on both my Hackintosh build (pretty modest i7 8700 and RX 580) and a couple Apple Silicon machines (MacBook Air and Mac mini - both with M1 chips)
and Perfect Golf runs really well on all three setups.
it runs best for sure on my hack with that RX 580, but it's quite usable and enjoyable on the entry level M1 machines also.
