Hey, it is supposed to run on a Mac with OS X. Perfect! So, after installing 8 GB of data on the hard drive, I start Myst IV and absolutely NOTHING happens. Oh yeah, read the really, really tiny fine print and then you notice that "laptop versions of these video cards are not supported". Sheesh, now I have two coasters.Ubi refers you to its website for support. Surprise, they don't even pretend to offer product support for Mac.You burned me once Ubi, never again.
