So I'm trying to install Leopard from a .dmg file on my iMac for a few days now. I got 2Gb, 4GB, Philips Ariaz GoGear 8GB(External HD Hopefully) and Blank rewritable DVDs that I think don't work because I've been trying to do it for days with the DVD. I need help really badly. I'm sick of 10.4. Just got a 16Gb flash drive. Hope that works. Help!!!!Please Sooner the better. Thanks again
