Hello,
I just got a MacBook and installed GR7 on it. When I try and change the input source from the built in microphone to my USB guitar cable, there is no option for me to choose the USB cable and the only option i have is Built-In. I checked my sound settings and the cable is registering as being connected and I allowed GR7 full disk access and microphone access. I also have restarted the Macbook and still nothing. Any help would be appreciated. Thanks!
