i.e. the only common device that does NOT work in duplex mode is the builtin device whose driver was written and is maintained by Apple. there is no technical reason that i know of for this decision, and in old PPC apple systems, the builtin device was also duplex.

There is one obvious technical reason: Power / Energy Savings. When you present both inputs and outputs in a single device you must also start/stop them in tandem. With duplex devices you cannot just run the output side, even if that is only what you need/want.

I’m not saying that’s the reason Apple did this, since I don’t actually know, but it could be.
