Blue yeti isn't working on my macbook pro!

Hello TheLordBars.

Thanks for reaching out to Apple Support Communities. I see that you are having some trouble with using your new Blue Yeti microphone. I will be glad to assist.

Fortunately, Blue provides a number of troubleshooting steps that can help identify the source of the issue. One thing to check is that the LED on the microphone is on. If it's not, it could indicate an issue with the adapter you're using:

"The LED on the microphone should be on. If it is not on please try the following:

1. 1. A different USB cable with the same USB port
   2. Different USB type A port on your computer with the originally supplied cable. Common issues:

• Some newer laptops only have USB type-C ports. If you’re using an adapter, please use a 1 to 1 adapter (One USB type-A jack for each USB type C jack). 
• Avoid using hubs or docks where possible, especially if they have intermediate software for device detection and management. Test the device with a USB port directly on the computer."

You can find additional troubleshooting in the "My mic is not picking up audio (MacOS)" and "My mic won't turn on (MacOS)" sections here: FAQs - Yeti - Blue Microphones

Hope this helps.

Cheers.
