Need help from a Mac user

I need help from a Mac user, not a Windows one, to test something for me.

Not a Mac user here, but it would sure help if you could mention what it is that you want to be tested so that someone would actually feel comfortable doing, and probably help.

I'm just working on a better GUI interface for an assembly that uses Windows functions that are not found in Mac operating systems.
While i'm relatively sure that it would simply do nothing if the function was not found, it's always better to be certain, hence this thread.
