Device information:

  • Type of Mac: MacBook Pro 13 inch - 2019 - Four TB3 ports
  • macOS version: now Big Sur 11.1, happened on Catalina already
  • BetterTouchTool version: 3.505 (please post the exact version - not just "the latest one")

Additional information (e.g. StackTraces, related issues, screenshots, workarounds, etc.):
BTT will work for hours without issues when suddenly I notice my fans spinning up.
I have not been able to relate this to any other action or software.

To "solve" the issue I need to quit BTT, wait 10 seconds and restart it. Usually at the first or second try this resolves the issue, for a couple more hours.

I have tried several things already as suggested in this forum:

  • Disabled preference sync
  • Removed preferences not needed
  • Turned off the touchbar functions

My iMac 27 inch Late 2015 does not show these issues, even though it has the same config (since I used to have preference sync enabled). I use the same software on both.

Unfortunately that sample doesn't show anything too weird.
It seems to be a bit busy writing some logs - maybe something is going wrong there. Maybe some file permission issue or something like that.

Could you go to Help => Export Diagnostic Debug Info and send it to andreas@folivora.ai?

Maybe afterwards try to reset BTT by deleting the ~/Library/Application Support/BetterTouchTool folder (but first make sure you have an export of your setup). This should resolve any file permission problem that might be there

I had this issue for a while as well. I became most annoyed when I upgraded to Sonoma. Tried alpha BTT - didn't help.
FYI I have a remote trackpad in addition to the built-in one. Macbook Pro 16-inch 2019.

I renamed ~/Library/Application Support/BetterTouchTool into "OLD_BUTT" (as an insurance policy), and tried to launch it. It helped!
