No audio data from input channel on Mac OS

I have an audio app and it works well with my soundcard(MADI, 64 channels) on windows10. The app reads audio data from input channels and plays after processing.
But I cannot find any input data when I transplant the app onto Mac OS…The properties of the soundcard are all right, e.g, 64 ins, 64 outs, 48000 sample rate, 1024 buffer size, etc…
What is going wrong?..

Most likely a permissions issue. You probably haven’t enabled “Microphone access” in the Projucer.
