I'm now looking at Mac OS X support, but this appears to be much harder than I expected. The developer documentation [4] isn't very helpful. It contains lots of information, but appears to lack the info I'm looking after (e.g. how to connect to a device, send/receive data, etc). The fact that I don't have any experience with Objective-C code or the Mac framework doesn't really help either. So if anyone can provide some assistance here, that would be great! Ideally, I would like to avoid using Objective-C code completely and use the C api of the Mac framework instead.
