macOS Big Sur 11.3 allows gamers who run iPhone and iPad titles on their Apple silicon Macs to use a keyboard or a keyboard and mouse combination as an iOS game controller.
- Use Mac controls in touch-based iOS games.
- Map controller actions to keyboard keys.
- Map these to mouse buttons, too.
- No controller required at all!
Emulating iOS game controllers on M1 Macs
MacRumors has more on how that works:
When running an iPhone or iPad app, opening up the preferences brings up a Touch Alternatives and Game Control interface that can be used to make touch-based iPhone and iPad apps run better with Mac controls.
With Controller Emulation toggled on, common game controller buttons are mapped to keyboard keys and mouse buttons. X, for example, is mapped to Q, the direction stick is mapped to WASD, and Y is mapped to E. L1 and L2 can be accessed by pressing Tab and Shift, respectively, and the Space Bar is the A button.
This new feature in macOS Big Sur 11.3 should make playing touch-optimized iPhone and iPad games on Apple silicon Macs much easier than before without having to use a game controller at all. If an iOS/iPadOS game doesn’t support game controllers, this feature won’t work.
macOS Big Sur 11.3 lets you resize iPhone and iPad windows and provides the aforementioned Touch Alternatives feature for mapping taps, swipes, drags and tilts in iOS titles to keyboard keys (Controller Emulation and Touch Alternatives cannot be used simultaneously).
The update also adds support for the latest PlayStation 5 and Xbox One X controllers.
