Unidentified developer (on Mac at least)
I'd just like to make a quick comment about the unidentified developer issue. On my Mac (Mojave OS), which has some admin restrictions (from uni), launching OpenSesame for the first time requires admin credentials because the application was not downloaded from an 'identified developer'. This is not a problem for me; I can get it approved. I'd just like to inform you of the issue. Surely you knew it already, though.
