Telescope drivers

The INDI drivers are required to drive the telescope. Look at this page to know if your telescope is supported.

The simplest way is to install a package for Mac OS X available from

You can also install INDI from source using MacPort.

  • If not already done, install Xcode from your Mac distribution CDrom or dowload it from Apple web site.
  • Install MacPort using the .dmg file for your Mac OS version available from
  • Install INDI from a terminal with this command:
    sudo port install indi
  • To update to a new version use this command:
    sudo port selfupdate
    sudo port upgrade outdated 


Wine is required to compute the artificial satellites position in the Calendar.

The easiest way is to install a pre-build package available from

You can also install from MacPort as for INDI. The most tricky part is to make the new PATH environment know from the applications launched from the Application menu.

  • Do the first two step above to install Xcode and MacPort.
  • Open a terminal and type:
    sudo port install wine
  • After the installation logout and login again, open a terminal and type
    wine --version

    to check it is installed successfully.

  • Type the following command to make it available from Skychart:
    defaults write ${HOME}/.MacOSX/environment PATH "${PATH}"
  • Logout and login again before to try with Skychart.
  • If it still say that wine is not installed, type the command:
    echo $PATH

    Copy the result and edit the file /etc/launchd.conf to add the following line including the full content of your $PATH environment:

    setenv PATH /opt/local/bin:/opt/local/sbin:...


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

  • Download the DOSBox dmg from:
  • 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/ /opt/local/bin/dosbox
  • To test, type dosbox from a terminal.

Video recording

Video recording requires the ffmpeg software.

You can install it with MacPort

  • Install MacPort as indicated above for INDI.
  • Install ffmpeg from a terminal with this command:
    sudo port install ffmpeg

A static version of the program is also available here:

You can also try to install it this way.
