Is there an equivalent to Linux DBus on OSX? I mean, is there a "message bus" available by default on OSX?
Disclaimer: OSX newbie here.

A:
Probably the closest analog would be distributed notifications (or notifications for same-process communication). It's not a perfect analog, but it fits into roughly the same niche. You can read more about it in Apple's Notification Programming Topics, particularly the part about the distributed notification center.

There's Mach's ports, which will probably do what you need: http://en.wikipedia.org/wiki/Mach_(kernel) .

hmmm... from a quick browse, it appears that "Mach Port" is really just an IPC without the higher level semantics of publish/subscribe... or am I mistaking?

@jldupont: yes, Mach ports are just queues and are the lowest level of IPC in Mac OS X - there are various other IPC mechanisms built on top of these.

@Paul R: thanks for the clarification. +1 for pointing me in the Mach Port direction... didn't know about those.

@jldupont: you might want to look at things like `Mach messaging`, `kqueue` and `notify`, depending on what kind of level you want to do IPC at. Get Amit Singh's book if you're serious about this kind of stuff.
