Even though in the pref pane for Trackpad it says "Swipe between full-screen apps" when I'm using the internal trackpad in my laptop, it will switch desktops even if I'm not using full screen apps. However, when I'm using my Magic Trackpad, the 4-finger swipe does not switch desktops.

Anyone have a solution?

  • If anyone else runs into the same issue, one thing you might try would be to delete ~/Library/Preferences/com.apple.driver.AppleBluetoothMultitouch.trackpad.plist.

Do any 4 finger gestures work? If not, it's likely the trackpad faulty and not just some software bug in Mission Control.

  • Yeah, default Mission Control and Launchpad gestures work. It's the switching between desktops/full apps that doesn't work.
