This is my first post. I'm fairly new to the Mac OS. Switched from evil Windows. World is much more stable. I want to upgrade via clean install to snow leopard. I have read mixed messages that this can and cannot be done. If it can, can someone please post some clear and definitive instructions in how to do this from the upgrade disc of snow leopard. I currently have: - Original Leopard disc 10.6.5 - iLife 2009 DVD (purchased separately) Cheers.
