=== Installer sur Mac OS X ===
Installing [[FlightGear Mac OS X|FlightGear on Mac OS X]] is very simple. Just drag and drop the FlightGear icon to the <tt>/Applications</tt> folder. That' s it. The first time you launch FlightGear, its icon on the Dock bounces for several seconds while loading aircraft and airport info. When the GUI launcher appears, select an aircraft and and airport by clicking the "Gear " buttons at the right of the names. Pressing " Start flight" will launch the simulator. You can configure more options using the GUI launcher. see http://macflightgear.sourceforge.net/home/documents/users-guide/ for more details.
If you want to launch flightgear using command-line, launch <tt>/Applications/Utilities/Terminal.app</tt> and type the following.
The [[$FG_ROOT]] and [[$FG_SCENERY]] are not set on Mac OS X. If you want to specify these variables yourself for command- line use, run the followings on Terminal.app:
After launching the GUI launcher, you will have the alias to [[$FG_ROOT]] at $HOME/Documents/Flightgear/<version> so you can browse the data folder using Finder.
