EFIX seems like a good way to get your GLBasic programs onto the Mac, for those who dont own a Mac?
Efi-X is a EFI-Emulator like PCEFI but commercial. It boots into retail leopard dvd and install a virgin leo on your harddrive. But you hardware must like a mac. All things EFI-X does, you can make by yourself without much work.
