I finally gave up trying to find a Mac alternative to MP3Tag. I installed the trial version of CrossOver but didn't want to pay $60 just to use a couple of apps. Luckily, there was a MacUpdate deal on CrossOver last week for $25. After installing MP3Tag and copying over my config files all I had to do was modify the paths.
No complaints since doing this? I actually installed VMWare and use the MP3 Tag & Rename on the windows side to my tagging when needed. What a pain.
