have a version the lfs for mac??

Nope. And probably never will.
Linky.

What sort of Mac are you on?

If you're on an old PowerPC Mac, then there's no chance of you ever playing LFS (unless you fancy about 1fps under Virtual PC)

If you've got a new Intel Mac, you can run a dual-boot install of OS X and Windows XP. Get yourself an XP SP2 disc and head over to http://www.apple.com/bootcamp
