Then a small company came along and introduced something called the EFiX. A small USB-based device, the EFiX connects to a motherboard’s internal USB header, and transforms it into a nearly authentic Mac system. By nearly, we mean the EFiX actually tricks a retail copy of Leopard into thinking that it’s been installed on a real Mac. With this setup, users don’t have to patch their operating systems nor do they have to worry about crippling their setup due to a system update from Apple.
