Hi, Im running 10.5.2 Zephyros on my ML115 and works fine, but i have one problem and need your help
When i installed Xcode 3.0, my system was freeze and i must force power-off.
my system was gone..... and i must reinstall 10.5.2..... :<

any solutions ?

This is related to 3 CHUD kexts in the /System/Library/Extensions.

Boot with -s, go to the aforementioned folder and delete those kexts.

And to install Xcode after you delete CHUD you need to de-select the option from Xcode install screen. Also I couldn't just delete the CHUD kexts i had to boot with -x -f -v and go to the CHUD folder that was installed and there is a uninstallCHUD.command file that will remove it all.
