Hey, I am attempting an install of Beta 1, 3, and 4 on an iMac DV SE (400Mhz) The results are below: BETA 1: Boots to installer, I try to slice the disk and it gives me an operation not permitted error. Ethernet works, can't install. BETA 3: Same as above BETA 4: Doesn't Boot. Anyone care to help me out with possible solutions???? Thanks -Dave
