    USB audio codec not recognised after update
    Hi All, I'm having a problem with my MacBook Pro's audio. I use a usb computer interface with 2 audio inputs for recording. Since the last update it isn't working right, I go to select the usb audio codec in the inputs and output tabs and it keeps telling me that the device has 2 available outputs and NO inputs. Which is the opposite way around. I've used this device with the Mac on the previous version of the os and it's definitely a Mac issue, not a problem with the daw. Device still works fine with windows machines so it's not broken. Any Ideas? Input would be greatly appreciated, thanks.

    What Mac? What version of the OS? What interface? Need a lot more information to begin troubleshooting.

    You might try installing Mojave to see if that fixes the codec problem. Make sure though that you have a cloned backup or at least a Time Machine backup that you can revert to in case things don't work out.

    Also, might be a good idea to check with the manufacturer of the Art USB Dual Preamp to see if it's compatible with the later releases of macOS. Most audio devices are built to work with Windows and then maybe macOS as a second effort.

    So why not just go back and use the older OS where it all worked???
