We advise you to use the latest stable Unity-3.5.7 version for Mac OS X 10.5+/10.6+/10.7+/10.8+
You can download the previous versions of Unity right here. As always you can use the free version, or if you have a Pro license, enter in your key when prompted after installation. Please note that there is no backwards compatibility from Unity 4.0; projects made in 4.0 will not open in 3.x. However, Unity 4.0 will import and convert 3.x projects.
