And that is exactly the reason why I want to leave Mac OS X ! I chose it two years ago because I thought it is a pure unix with the ability to run commercial software. But the more I looked inside Mac OS X I noticed that is not that kind of unix I was looking for. I want the speed and the customizability of unix and that is what is not available in Mac OS X. Mac OS X runs out of the box, but that is the only option, there is no way to change Mac OS X it is always like you get it when opening the box
As I am more familiar with unix now I decided to choose FreeBSD but I have to replace some apple applications I use everyday and that is what this thread was desired for.
