Mouse tracking speed changing itself

[Crazy Badger]

This is really annoying now, and not sure if it's a 10.10 thing or not.

On my iMac running 10.10 the mouse and trackpad tracking speed keep on resetting to the default position (4-clicks to the left) when I like it on Fast so I can get around the desktop with one movement.

Any one having a similar issue, or know a simple fix?

Cheers

Not completely the same issue.
My mouse behaviour changed completely since 10.10.

The same setting as in Mavericks but the mouse was a lot faster en chaotic on the display. I installed a few mouse changing apps.

Eventually I stuck with: MouseZoom / Sits in the settings app. (Sorry I don't have a link anymore).
It works, never got the right settings back. But I think I developed a new muscle memory. Typing is still different than it was. I think it will be better if I buy a new Mac...

a bit late, but notice this lately and its bugging the crap out of me...

i have the exact same problem. 10.10.2 Mac Mini 2012, Magic Mouse. Tracking speed keeps reseting itself after the mouse goes idle for a while, always back to default.

I'll have to consider a different mouse if this carries on... anyone got ideas? 😕

Same problem

Same problem ever since i started using a Logitech G700s.

Tracking speed randomly changes, although it's set at a specific level in mouse (system) preferences, and the level does not change.

Magic Mouse

yes, having the same problem,,, MacMini 2014/15 Magic Mouse,,, everytime I'm using the Mini, Mouse Tracking Speed is set to default, have to manually update to fast. Wonder what it could be,,, Yosemite 10.10.3

Deleting the mouse/trackpad plist files and rebooting has always fixed these issues for me!

Would you care to elaborate? Where would a regular joe shmoe like myself find this plist file??

~User/Library/Preferences and look for the files such as com.apple.driver.AppleBluetoothMultitouch.mouse.plist

I think I eventually pinned my problem down to connecting to my Mac via the RealVNC client on my iPad.
