I am running X-Plane 10.45r2 on my Mac - El Capitan 10.11.5. After 2-5 minutes of flying (F-4, Cessna 172) the program stops running, returns me to the desktop and notifies me "X-Plane 10.45r2 quit unexpectedly". Have uninstalled and reinstalled the program (and updates) a number of times to no avail. I love X-Plane but am so frustrated I'm ready to put the discs in the shredder. Can anyone out there help?
