My Macbook Air does not have this "Use audio for:" option, as it has been excluded from Airs for whatever reason. How do I change my audio output to input without this?

If I have to buy an audio-usb converter let me know.

Although if this is an option exclusive to Pros and I do, then this is a little ridiculous Mr. Ghost of Steve Jobs.

Especially considering how Airs don't have their own section here on the forums

Thank you for whoever responds! All the idiot "how to" links on Google have me a little frustrated
