You sure can ... I switched over to a MacBook last Feb and I was playing a great career game on FM2007. The fact that the PC and Mac version are both on the same disc is fantastic if you ask me. I copied my save game over to my Mac and it worked just fine!
In fact it plays much better on my Macbook (which are not very good for games in general) than it does on a PC I built specifically to play games on. Although the fact FM isn't very graphics intensive certainly helps.
Currently playing FM2008 on my MacBook and that is working just as well.
Enjoy
