Three finger click not working properly after upgrade from M1 to M2 macbook air

Describe the bug
Hi, I use three finger click to mimic middle click for a year without problem.
Yesterday I upgraded my macbook air from M1 to M2.
After system migration, I encounter 2 problems when using three finger click.
These problems stick even after I upgraded BTT to latest version.

  1. BTT does not block system event/haptic feedback anymore, resulting 2 haptic feedback. (the system feedback triggers at a fixed force, BTT one triggers based on "FORCE Touchpad" setting)

  2. Three finger click randomly not being recognised and trigger system 2-finger click instead. It somewhat depends on finger placement, works ~100% if I put all 3 fingers near right edge of the trackpad.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Built-in trackpad

Device information:

  • Type of Mac: M2 macbook Air
  • macOS version: 12.5 (21G72)
  • BetterTouchTool version: 3.826

Can you go to Help => Export Diagnostic Debug Data and send the result to me? (

Sent, Thanks.

P.S. I always have palm filtering disabled

Thanks for the logs! The M2 Air trackpad should now be handled correctly in the latest alpha of BTT (3.829)

Thanks. I installed 3.829, but unfortunately the problems are still around.

Hi I tested with a bluetooth connected magic trackpad2, and it works perfectly. So it's only the internal trackpad which has problem. Hope it may help.

Also, even if I disable all trackpad shortcuts and set haptic feedback to "no feedback" in "FORCE Touchpad", 3 finger click still has a haptic feedback.

No feedback if I quit BTT.

The force that trigger the feedback obeys the force setting in "FORCE touchpad"
