### DOSBox

If you also want the Iridium flare prediction with the satellites pass you need to install the DOSBox software.

- Install in /Applications
- To let Skychart use it, copy the binary file to a location in you PATH, for example the same location as Wine above. Be sure to rename the file with all lowercase letter when you do the copy:

      sudo cp /Applications/DOSBox.app/Contents/MacOS/DOSBox /opt/local/bin/dosbox

- To test, type dosbox from a terminal.

Video recording requires the ffmpeg software.

You can install the OS X version from http://www.ffmpeg.org/download.html
