Have just installed this great addition to my aircraft library. I use MAC OS Catalina and after unzipping the downloaded file and dragging and dropping the folder into the ...Aircraft\Laminar Research ... folder the plane magically appears in the list and is selectable.
Problem is that although I have the downloaded serial key, I don't know where to put this so that I can see the flight deck without the two AI aircrew seated there.
There is a way. I have done it before, but cannot for the life of me remember how to do it.
