If I create a Unity 2D project, shouldn’t it set the camera to ortho and set the position correctly? It is not doing so for me. I have removed and reinstalled Unity 4.3 multiple times. I am using a 2012 macbook pro, OSX Mountain Lion.
There’s no particular reason to set the camera to ortho. The camera position is whatever you want it to be; there’s no “correct” position. Also there’s no need to uninstall and reinstall Unity; it won’t change anything. You can click on the 2D button to toggle the scene view between 2D and 3D mode.
