Sorry for confusion. Let me explain:
AmiKit DOES WORK on Mac, of course. This means you have to boot your Mac OS X first and then install & run AmiKit (supplied as .dmg installer).
AmiPUP is a different story. It is an independent bootable Linux environment where AmiKit is pre-installed. This means the computer boots into AmiPUP directly. No other host OS is required. While AmiPUP works with almost any x86 computer, it does not work with Macs. So, unfortunately, you cannot use AmiPUP to boot your Mac.
Anyway, the AmiKit USB flash disks contains AmiKit for Mac (as well as for other platforms) and bootable AmiPUP (which, like I said, doesn't work with Macs).
