I think this is the Mac version. Where are the Windows and Linux versions?

I was in a rush when exporting from unity and when I was going to build I saw Mac, linux and windows together in a group build setting and I thought unity was going to make an app that ran on all three and only after the deadline I realized I could only choose one OS for every build and so there is only a Mac version. Sorry.
