When I create a script on mac, unity crashes!

So, i create a project, it can be completely empty or with some sprites, it doesn’t matter, 3d or 2d, when i create a script, Unity Bug Reporter pops up and i have to force quit unity!
I need help with this please! it also crashes for some other things like importing packages and some more!
BTW i think it could have something to due with MonoDevelop (i can’t open it as well) it won’t even open D:

Using Mac OSX Version 10.9.4

You have to install Unity under application, hope that will work for you
