I'm PC, not Mac, but I like .exe just as little - every time I get free stuff in an .exe I am forced to start up my virus checker and go thru the file first, and even then I don't like it, since the file can do anything it likes with my system once I run it and all I can do is watch. I put up with .exe from DAZ (have no choice) but otherwise, I DON'T LIKE THEM! Avoid them at all costs, it's unnecessary to use them. Zip is way better. Then I control what happens on my PC. It's like Flash-only sites - cute but irritating.
