I would like to be able to play Myst III, IV, or V on my Macbook but I wasn't sure if I would be throwing my money away to buy them if they won't work. From what I understand, you have to have an OS 9 partition to play Myst III under OSX, is this true? Does anyone know if these games will work with 10.5? I downloaded the Myst V demo for Mac and it crashes my computer all the time. Is this just a demo issue or will the game do this too?? My Macbook is 1.83ghz intel core duo, 2 gig of ram, running Leopard.
