Running multiple Yeti Mics

Does any body know how to get two. Blue yeti mics to work on a Mac Book Pro using Audacity. For some reason Audacity only recognizes one of them and not the other.

Mac aggregate device

This does not have anything directly to do with the topic you posted in about a single Snowball mic on Windows, so I started a new topic for you.

Does Applications > Utilities > Audio MIDI Setup recognise both Yetis? If not, device aggregation won’t work. I am expecting the Mac will only see one of the mics if they are identical, due to an Apple limitation. See Problem with 2 of the same USB microphone.

The upshot is you may have to send the mics back to Blue to be given unique USB identifiers.
