Profit on the Mac requires X Windows; either the Apple X11 server or the XFree server must be installed. After ensuring that X Windows is running, simply open the ``bin'' directory and double-click on the profit.command icon. This has the side-effect of running the ``Terminal'' program, and will fail if X Windows is not running. The Terminal program can be exited after running Profit. This is a workaround that we hope to avoid in a future release.
If you have problems installing Profit, please inform the developers using the Feedback form on the profit web page, http://heasarc.gsfc.nasa.gov:/docs/software/profit/
