It's a GNU/Linux distribution so the environment is not far off of OS X (they're both Unix-like systems). If you've done any pentesting in Windows (god forbid), depending on the libraries you used you could find yourself hard pressed to find OS X equivalents. Kali comes with a standard set of tools that you could utilize right after installation.
I second this, if you're really serious about it don't even consider a Mac or any other Apple Product, get a good computer and Kali.
