I installed iPC 10.5.6 on my Gateway MX8738 laptop Core Duo GMA950 using an external usb hdd. My main system is iATKOS v5i updated to 10.5.6 vanilla. I checked video, Intel SATA, Powermanagement pkg, clamshell, AppleSMBIOS Anv MacBook Pro, PS/2 keyboard fix, and everything went fine with a post install of sound patch, trackpadpane, and kext for side scroll. The big change that I noticed with this system is that itunes new smart playlist DOES NOT crash itunes. This worked with both itunes 7 and again with 8 after I did all software updates. Has anyone else noticed this problem "fixed" with iPC Leopard? Nice DVD!!!!
