Can't record MIDI on PSR E343?

[Alchemized]

Hi.
I've been trying to record MIDIs on my PSR E343 but I can't. I have a Mac, when I connect it to my keyboard using the USB port it doesn't show up on the sound devices tab. I try to record on Audacity but it just records my microphone. I've read the manual and I've read online and don't know what to do.

You mix two things, recording on Audacity is audio.
MIDI has nothing with audio compared.

What you can do is visit the Yamaha website and hope that a mac OS driver is.
