#Jumpy scrolling logitech mouse mac mac os x#

Hello Adam, this particular bug has nothing to do with Mac OS X mouse acceleration. On the opposite, on snow Leopard, when you move the mouse rapidly, the curve is made with segments On XP, when you move the mouse rapidly, the drawing remains smooth. For example, I tried to make drawing curves with the same mouse on Paint on XP, and Paintbrush on Snow Leopard ( It is nearly the same softwares ).

The first one concerns the bad acceleration curves of OSX, and the second one the bad USB polling rate. But even that, is not good enough.Īs far I am concerned, I think that there is 2 issues. The best walkaround for me, is using a Microsoft Standard USB Mouse with ControllerMate and a custom acceleration curve ( like in Microsoft XP ).

I use my Macbook every day at work, and I feel very uncomfortable: I can’t use my wrist anymore in the evening. I tried different mouses, different OS ( 10.4, 10.5 and 10.6 ), different hardwares ( iMac 20, Macbook unibody, Imac 27 ), different softwares ( steerMouse, USB Overdrive, ControllerMate ) but no way ! Since 2007 and my first iMac, I unsuccessfully looked for a method to resolve this mouse issue.
