GM4Mac is still a very new product, but people tend to focus on the bugs instead of the flexibility of Mac OS, that can be used by your game if you have just a little bit of knowledge on how Mac OS works.
'Dlls', aren't supported, but dylibs (dll for mac) are. I am the author a few of these.
I suggest you check the Mac Creations Forum. There's a few games, extensions, and stuff there. You might be surprised.
Also, if you just want GM4Mac to 'port' over your windows games, then it's not going to work. The Mac audience for gaming is negligible anyways, waste of time. If Mac OS isn't your main platform, then you shouldn't worry about porting stuff. You won't gain fans, trust me.
