Hello eebow421, we are sorry to hear of your frustrating start. There are indeed a few extra hurdles in place for Mac users, but with a few adjustment we believe that you can experience much the same thing as the Windows platform users. For instance, all DLC will work on the Mac and cross-play between Mac and PC users is fully supported. Please see the post below with some additional tips to adjust to using Fantasy Grounds on the Mac.
