Mac mouse is too sensitive. Anyone know how to relax it?
I had the same problem, with a new iMac: I was getting a lot of random scrolling, in the middle of editing work, and it was very annoying.
Contacted Apple and they told me to do an SMC (?) reset, which changed nothing.
I then realized that the problem was from an over-sensitive Magic Mouse. Many users seem to complain about this over-sensitivity, especially for newer computers.
So, a while ago, I took the following advice the website at the end of this post.
Control the touch-sensitive area of this mouse with the free app MagicPrefs (not clear why Apple does not provide something this useful):
download it from http://magicprefs.com/ and install
then go to its Preferences
in the new window that opens, click on Configure Scrolling, at the bottom right
you will then see the sensitive area of your mouse
click and drag to reduce that area
I had found that especially touching the edges of the mouse start the random scrolling
so, I made the touch-sensitive area for scrolling very small, and in the top-middle of the mouse, about where the scroll-wheel would be on a normal mouse.
Hope this saves you all a lot of frustration.
P.S. I learned about MagicPrefs from one of these frustrated people
