Being reasonably confident that my GUI design will work on Windows and Linux, I wanted to make sure it would also work for Mac computers. The first step was to compile Leadwerks Game Engine in Apple's Xcode IDE. Like Visual Studio and Code::Blocks, I was able to create two targets so that the same project can be used to compile both the static library and standalone executable.

At this point the Window class for Mac contains mostly empty functions that don't do anything, but this is a first step.
