I am new and running 10.6. Works great on this Dell n4010 (i3-350m / ati 5470) with tonymac's iboot as a startup disc...and it starts up without the need for any boot flags...but every time I try to update to -- virtually any of the OS updates -- the thing gets to 96% and suddenly Kernel Panics. What do I need to change in order to get past 10.6?
