How do you make a video game on a mac
OK,There are many, many, ways to do this. It is made much easier if you have had programming experience, preferebly in C/C++/Obj-C. If you don't know what I'm talking about, look at Scratch (google it) or TNT BASIC (google it too). A few other options are:
Unity 3D (free, easy, lots of help, 3D amazing graphics)
Dim3 (free, not so easy)
Torque (expensive, don't know)
Scratch (free, very easy 2D only, loads of help)
TNT BASIC (free, not so much help, quite tricky)
Xcode (free, very tricky, need programming experience)
If you know what C/C++ are, then look at Xcode (Apple Developer Connection). This is just about the only decent IDE for the platform.
If you really don't know, visit

Good Luck!
