As I understand it, Macs and Itanium were just the first adopters of EFI, the new boot method to take over the old school bios / mbr system. GPT is the disk partition part of EFI: http://en.wikipedia.org/wiki/GUID_Partition_Table We are in the transition period between the two, with gpt being the future. IIRC there is a 2TB limit for mbr partitioned disks... we will all be running gpt soon enough
