After switching computer and moving from my old laptop (which ran Windows at first, and later Linux) to a MacOS computer, my old mouse became incompatible. It worked very poorly. I didn’t know how to fix it.
I read online that my mouse was incompatible with the operating system and that this happens. Indeed. I found many mouse comparisons and descriptions of which mouse are compatible with which operating systems. I figured I’d have to buy a new mouse, even though my current one is perfectly fine.
