Subject: Troubleshooting Trackpad Gesture Lag on MacBook Air M4 (macOS 27.0)

If your MacBook Air 13-inch with the M4 chip running macOS 27.0 experiences lag when using the three-finger swipe-up gesture to open Mission Control, please try the following troubleshooting steps.

1. Verify trackpad settings: Go to System Settings >> Trackpad >> More Gestures >> Mission Control and confirm the gesture is configured correctly. 
2. See Apple’s guide to Mission Control.
3. Restart your Mac: Restart your MacBook Air and test the gesture again.
4. Check for macOS updates: Go to System Settings >> General >> Software Update and install any available updates. See How to update macOS.
5. Check system performance: Close unnecessary applications and windows, then test whether the animation remains sluggish.

Compare other gestures: Test swiping left or right with three fingers to switch between full-screen apps or desktops. You can also press Control–Up Arrow to open Mission Control and compare its responsiveness.

For details, see Apple’s Multi-Touch gesture guide.

If the issue persists, please provide the following information:

• Does the lag occur every time or only occasionally?
• Did it begin after updating to macOS 27.0?
• Does Mission Control also lag when opened using Control–Up Arrow?
• Does the three-finger swipe-left or swipe-right gesture also stutter?

This information will help determine whether the issue is specific to the trackpad gesture, system performance, or a potential macOS software issue.
