Use Your Mac for Gaming With Game Mode
Historically, Macs have never been ideal for gaming. Sure, you can play games on them, but PCs have always been the go-to option for gamers.
Apple wants to change that, which is why it is introducing Game Mode in macOS Sonoma, a new feature to help games perform better on your Mac by prioritizing them when they’re in full screen.
Game Mode is meant to give the game you’re playing top priority access to your Mac’s CPU and GPU while reducing utilization by any other apps running in the background. It also ramps up the Bluetooth hardware to ensure a lag-free response from wireless gaming accessories like controllers and headsets.
Game Mode should turn on automatically as soon as you put a game into full-screen mode, but you can toggle it off by clicking the Game Mode icon in your menu bar and disabling this feature.
