Hi all, this is odd. X-Plane has been installed on my iMac (running 10.11.6) since March 2016, upgraded to 10.50r3 probably July time I think. Basically, nothing has changed with the install since, been using it happily, but not used it for a couple of months now.
Tried to start it up: window goes full-screen, with the product key window in central screen - my product key is displayed, so I click "unlock full version" as per usual, and.... nothing.
Well, not quite true, the Mac OS "Activity Monitor" app shows the X-Plane process thrashing away at 60-90% CPU, but it never moves on from this product key screen.
I really don't know what could possibly have changed to cause this - any ideas please?
