Short answer: No, you being on mac shouldn't make the difference.
Okay! This post is lacking a lot of detail, so I'm not to sure how I can help you when I don't really know what you have done/haven't done.
Assuming you are using the .exe given to you in the .rar file and you're launching it in winebottler(Or something like that.)
Make sure (And I mean go and check it don't assume.) that your realmlist is "set realmlist play.wowfreedom-rp.com"

It should look like this.
Also check to make sure winebottler (or whatever you using) isn't blocking any of wows ports or its connection to are server!
That's about all the help I can offer until you can tell use some more details. <E>
