Middle click stopped working Mac OS 26.1

[renelukkien]

Middle click is not working for me anymore on my Macbook Air M3 with Mac OS26.1 version. I can open the v1.11 middle click app normally and it also shows the checkmark for three vinger light click but nothing happens.

The issue started about a week ago. It might have started after the last Mac OS update, I am not sure. I have already deleted and reinstalled the middle click app.

When this happens, the reason is typically that the Accessibility permissions are no longer in sync. This sometimes happens with a macOS update. To fix it, try the following:

1. Quit Middle
2. In System Settings -> Privacy & Security -> Accessibility, first disable Middle, then remove it with the minus button.
3. Launch Middle and enable settings for it as prompted.

It's also possible to do this with Terminal commands:

killall Middle
tccutil reset All com.knollsoft.Middle
open -a Middle
