Just a note: turblety's comment does not make any allegations to the effect that you can't /run/ compiled lazarus apps on macs, just that it seems hard to set up a lazarus dev environment on that platform.
I can verify turblety's comment. I've tried multiple times to get Lazarus working on OS X, and the closest I've gotten to getting it working was the IDE to actually show up, but crash trying to get the Hello World example to compile and run.
