Mouse jumps around?
 

(Snow Leopard) My mouse jumps around once in a while, just skipping around while i drag or move things. Is there a fix for this?

I heard its appleupstreramuserclient.kext but I am not sure.

Is it the OSX acceleration?

I think it is but even if its not, I'm glad to remove any DRM crap.

Are there any fixes?

Just rename it to something so it wont be loaded

Check my guide!

My m8 Pista modded the SleepEnabler to include a fix for this on my request.

It's the same lag as with Leopard only less obvious.

Please add [solved] when your problem is fixed with this so people with similar issues know when there's a solution available.

Thx

But it says that version is not modded to include the fix? and the link is broken too.

delete the AppleUpstreamUserClient.kext from /System/Library/Extensions folder.

worked for me..

Make sure the network cable is connected from your modem to your computer because the link is working just fine.
Modded kext is seperatly shared, unmodded is in kext package.
Also replied to you via PM and edited my guide to make it even more understandable.

Hope that helps

I have this problem too, but it is almost not noticeable.
