I wonder if anyone happens to know how to do this "hack" on a Mac? (Useful for tanking in BoS, to help collect the mobs)

I ask because, I can locate the file (inside the Crossover windows simulation on my Mac), but can't open it to make changes.
The distance "hack":

"on your computer search for the rift.cfg file"

"open it using notepad and edit the camera distance values...."

"save the file and launch rift...
you can now scroll out til your character is just a spec.."
