10.6.8 kernel panic at startup (fixed)

**excuse my english since I'm french**

Like a lot of people, I've installed 10.6.8 through software update. And I've experimented kernel panic at startup. So, I unplugged everything (my two USB hubs with multiple peripherals) except the original Apple keyboard and Apple wired mouse. And restarted in safe mode. Downloaded Apple 10.6.8 combo update, install it and restart. Everything went fine. Great.

But as soon as I plugged back my USB hub, kaboom! here's come the Kernel Panic again.

So, one by one, I plug and unplug my peripherals. To discover that my old optical wired two button mouse (love that mouse ;-))) was THE problem. Even when it's plugged directly in one of the USB port on my Mac Pro. I've try with three different optical USB wired mouse, one Logitech, one Dell and one Verbatim (my old mouse): kaboom! Kernel Panic. With my Microsoft optical wireless mouse? No kernel panic. 10.6.8 crashes only with third partys wired mouses, except the Mac wired mouse.

Voilà.

So, I'm stuck with the old wired Apple Mouse (that I hate). But no more kernel panic.

Hope my story can help someone.

And Apple, I missed my optical two buttons wired mouse. ;-))

Thanks jossue! And stephanos99! I bought a Verbatim bluetooth mouse for my son's iMac running OS 10.6.8. Kernel panic (gray curtain coming down over the screen, with the only recourse being to power off and reboot). I thought it was the mouse, so I returned it for a replacement. Same behavior. Returned it for a refund. Then brought several other mice to try. Both a different bluetooth mouse and a USB mouse induced immediate kernel panic. This despite the Apple bluetooth mouse and keyboard working fine. So I deleted MouseSetting.kext and rebooted and VOILA! (with a tip of ma chapeau to mdumais en francais for starting this thread). Now all mice work perfectly. I had 3 mice all working at once. THANK YOU! And hey, Apple, how about fixing this awful bug?!

Using Console to find which extension was causing the conflict was the key.

My .kext document was different than any of these, but thanks to this thread I was able to track it down.

Thank you for the information. Had the same issues and apple support had no clue, wasn't sure if it was the mouse, but his article links directed me here. MacBook G4 with Verbatim laser bluetooth mouse = immediate kernal panic error after login. Started in safe mode, updated all software listed, reboot from 10.6.3 install disk, ran disk utility, repair disk and disk permissions, restart regular, then I finally found the MouseSettings.kext and deleted. Restarted and everything works! Thanks so much!
