BetterTouchTool 6.143 on macOS Tahoe 26.2 blocks all mouse clicks & keyboard input until BTT is quit

Describe the bug

After running BetterTouchTool 6.143 on macOS Tahoe (26.2), all mouse clicks and keyboard input become completely unresponsive after certain system dialogs appear, while the cursor can still be moved. The system only recovers input when BetterTouchTool is terminated. This happens at least once per day.

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

  • Bluetooth mouse (Logitech MX Master 4)

  • Bluetooth keyboard (Apple Magic Keyboard)

Screenshots:

Not applicable (freeze state cannot be captured easily).

Device information:

  • Type of Mac: Mac Studio

  • macOS version: macOS 14 Tahoe 26.2 (latest)

  • BetterTouchTool version: 6.143

Additional information (e.g. crash logs, related issues, etc.):

  • Issue occurs sporadically and cannot be reliably reproduced by specific steps; it typically appears after interacting with system dialogs (installer warnings, permission dialogs, etc.).

  • Cursor motion remains functional, but mouse clicks and keyboard input are ignored by the system. When switching off the mouse, the keyboard works again. When switching the mouse back on, the keyboard works still until the first click with the mouse. Then the keyboard doesnt work at all and the mouse cursor moves but doesnt click. This can be repeated infintely.

  • The only way to restore input without rebooting is to terminate BetterTouchTool; quitting BTT immediately restores full input functionality.

  • Other utilities such as SteerMouse, Moom, and Keyboard Maestro have been disabled during testing and do not affect the issue.

  • The problem occurs even when BetterTouchTool triggers and actions are disabled, suggesting the issue is related to the BTT background process or how it hooks input events.

I noticed it too @Andreas_Hegenberg

Hello, same with 6.154

unfortunately I haven't seen able to reproduce, if you can figure out any pattern please let me know

any other mouse related apps installed in that could conflict?

Please advise how to create any debug logs or so when the problem arises.

I just bought BTT, but at this moment I disabled it and it’s useless for me due to this bug.

if the issue occurred, go to help -> export diagnostic debug information, then send the result to me (andreas@folivora.ai)

Afterwards you can also go back to previous versions for now:

Do you maybe all have SteerMouse installed?

Unfortunately/Fortunately there have been no similar reports yet. Have you been able to reproduce the issue?

One known macOS bug that can cause this to happen is related to accessibility permissions. If you remove the Accessibility permissions for BTT while BTT is still running, the system would lock up completely. (This affects all similar tools and has been the case for a long time)

I cannot produce logs, but this happened to me also, several times over the period of weeks. I didn’t realize it could be caused by BTT. I am not at my computer right now so I can’t look up exact versions, but I wanted to mention this.

BTT version 6.xxx (currently the latest non-beta release) through Setapp

MacOS Sequoia up-to-date

MacBook Pro M3

Magic Mouse

Logitech MX Keys

Never installed SteerMouse. At the time I had LogicOptionsPlus installed.

I am currently experimenting with BTT beta and Logitech kb configuration and LogitechOptionsPlus uninstalled so I will report back if it occurs again

LogitechOptions can cause the issue if it is running at the same time as BTT AND you have a Logitech Configuration added in BTT. If you want to use Logitech support in BTT, Logitech Options+ needs to be uninstalled completely unfortunately.

Just to make things clear: when I experienced the problem I was still on the latest formal BTT release with LogitechOptionsPlus installed and NO Logitech keyboard configuration in BTT.

I only switched to the latest BTT beta yesterday to test with the new BTT mobile app and found the Logitech keyboard configuration and decided to switch over, aka uninstall LogitechOptions, which I did.

in that case what you saw was most likely not related to the Logitech Options app! Let's keep monitoring, if anybody can produce logs that would be very helpful as this only seems to affect very few / specific setups.

Possibly add a trackpad gesture or non-mouse/keyboard related trigger that let's you quit / restatt BTT in case it happens again
