Steinberg UR12 Macbook Pro / XLR input signal issue

My UR12 sound card won’t give signal from the XLR to my Macbook(High Sierra 10.13.6).
I’m trying to use it with Garage Band. The other input seems to be working just right.
I can hear XLR microphone signal from the UR12 Direct Monitor but still there is no
signal to my Macbook. I have installed the most recent sound card driver.
