Upgraded to 10.6.2 using software update. Made mods suggested on netkas.org but had multiple kernel panics on restart. Re-installed MyHack with SleepEnabler.kext unchecked. Restarted and everything seems fine now.
How did you reinstall the myhack? Did you have to redo the usb stick without sleepenabler, boot with the usb, then reinstall to system HD? Just curious how you fixed it when you were getting kp's
