I'm on Big Sur 11.6.1 and the mouse will suddenly only right click. In other words, both left and right buttons act as the right button and so clicking just brings up a menu. It happens randomly, sometimes after 5 minutes suddenly after an hour.
It doesn't make any difference whether right click is activated or not in system preferences.
Restarting sometimes works and sometimes it doesn't and still right clicks straight away after the restart. Sometimes leaving it 10 minutes and coming back will have fixed it. It doesn't matter whether I'm on a wireless Magic Mouse or a wired usb PC mouse.
We have a 2020 21" iMac and it did this once 6 months ago and never did it again. But it started doing it on my 2015 27" iMac a week ago and now it does it over and over.
Seems like an OS issue but updating to 11.6.1 didn't solve it.
