I'm not really a "Mac" developer, since I don't (yet) code for the Mac APIs, but I'll respond anyway: I primarily code in Python and Javascript, but also some C/C++ non-GUI stuff. I tried a few different cross-platform Python IDEs, but nowadays I just use TextMate. I use iTerm for the terminal. TextMate's a great app for a lot of different things... Markdown, Python, C++, Javascript, Mail... it has a lot of plugins to help write code and text in different languages. That's great, and it allows you to be really productive. My only gripe is that it hasn't been updated substantially lately; while it's a great product as-is, I'd like to see a few improvements to the interface. My network programming has been mostly just from Python, but I haven't run into any problems with OS X's sockets. I'd imagine it'd be nearly identical to BSD systems, and I'd also suspect that it you would not encounter much difficulty shifting between OS X and Linux compiling. Someone else might know more specifics.
