There is a flight simulator similar to MSFS. Titlerd X-Plane. X-Plane is compatible for Linux, Mac OS X, Windows. I use a Mac Computer using Mac OS X 10.5.8. During the developement of the scenery you can release also for X-Plane? The current version is X-Plane 9.55 and for animated jetways you need a autogate plugin available in X-Plane Scenery Marginal and you can make taxiway, runway, tower view, bondary, taxilines and ramp start in WED. You can also convert a FS2002, FS2004, and FSX scenery into a X-Plane scenery with a tool named FS2XPLANE available in X-Plane Scenery marginal. To make photo scenery you need a tool called PhotoScenery X available in his page. there his also a tool in Photo Scenery X called ImageTool X.
