Hi,
I'm using the latest version of FG for Mac, and I cannot see anyone else's model unless I'm using the same aircraft model as them. My Mac is also quite new and the OS is updated to one of the more recent ones (10.14). So if I'm flying on MP on a cap10B, I can only see cap10b's, otherwise I see yellow-blue default models. Any clue on what the issue is? Also, some models like the 777 or the c172p appear to have completely black liveries except for the doors. Unfortunately it seems that Mac issues are not so well known.
