I installed Gretl on a MacBook Pro running OS X 10.8.2. When I leave Gretl in the disk image, it runs fine. However, when I move Gretl to the Applications folder it appears greyed out (and with a no-go trafiic sign across the icon) and won't run. Does anyone know what is going on and how to fix this?
