While I would love to chime in about how I feel about this mod and its "mages" add-on, unfortunately I cannot. This mod joins the ranks of other mods which, in making the installation process a little easier for the average windows user, renders the mod inaccessible to the average mac user. Short of dropping a couple hundred dollars for virtual pc and the windows OS, I can find no way to run an .exe format file on my macintosh. If it were a .zip, or probably even a .rar I would have no difficulties.
So, in conclusion: grumble grumble; grumble.
