Even though the mouse jumps are not that ocassional, they can get annoying at times so a fix would be nice. So if I delete the AppleUpstreamUserClient.kext kext, will the mouse stop jumping around? If so, what does this kext do? Is it safe to remove? I want to make sure before I delete or rename it.

The kext suposedly handles hdcp checking and enforcing when playing hd video to a external monitor over a digital connection.
It causes lag only with certain nvidia gpus and while quicktime/itunes is running. Better to use a disabler than deleting it, so you are protected for future system updates. AsRock P45TS | C2D E8200 | GeForce 8600GTS Mac OS X Snow Leopard 10.6.1 + Windows 7 Ultimate 6.1.7600 + Fedora 11

What disabler you mean? BTW, I am running fully vanilla, 64bit.
Edit: The problem occurs only when iTunes or Quicktime is open. It is minimum, but noticeable at times. Either way I found the fix. Last edited by chico_stang; 11-03-2009 at 11:52 PM.

Hello Guys,
I had exactly the same problem, noticeable lag all i did was remove the appleupstreamuserclient.kext, and that fixed the problem, but just rename yours and fix permissions on the drive to test.. Worked for me so everyone else should be good to go with that fix!!, Cheers, Rich. 💡 Deploy cloud instances seamlessly on DigitalOcean. Free credits ($100) for InfMac readers.
