The shiny and beautiful Mac with the M1 chip can run the Sims 4 beautifully even though the game isn’t native and requires Rosetta to run. There are two small niggles though which I’ve been a bit tardy about reporting here – sorry!
Freezing resulting in Mac restarting
I posted about this last November but just reiterating again. If you are experiencing freezing whilst playing, usually in CAS, just enable vsync in the game options at the main menu or open the Options.ini file in your Sims 4 folder using TextEdit, find the line for verticalsync and change the value to 1.
In-game audio crackle
This is pretty irritating and there doesn’t seem to be a fix apart from muting the sound. There is a thread here at Answers HQ so it’s worth subscribing to it if you want to see any updates.
