It seems as if your best bet is buying a cheap netbook or getting a PC, as the official publishers of GMAT Prep (mba.com / GMAC) say it's only for PC:http://www.mba.com/faq/gmat-prep/is-gma ... r-mac.aspx
If you have lots of time to try to find a workaround, then I guess it's worth it. But if you don't, then it may not be. Just IMHO.
