i have a mac and i tried instaling preform enabler. macs dont have unsip the folder and stuff so the same thing is to just drag all stuff out of folder into the WoW addons folder. i did this with other addons and they work. when i try it with pre for av enabler it doesnt work. any ideas anyone...PLEASE?

From some of the posts I've read here I've heard macs do have and unzip utility thought I'm not sure what its called.

That being said here's a link to the instruction on how to install addons.  http://wow.curse.com/articles/teek5449/284724.aspx
