Reply to DJM-900 USB light flashing .. MacBook not automatically bringing up Setting Utility

Hey, so not sure why this is happening now.. I normally don't have any problem plugging my DJM-900Nexus directly into my MacBook Pro via USB.. typically, as soon as I plug the DJM-900Nexus into my MacBook Pro, the DJM-900Nexus Setting Utility window pops up.. now for some reason, when I plug the DJM-900 in via USB, the green LED indicator light is blinking right under where the USB on the DJM comes out from..

so basically, flashing LED indicator light under USB on DJM-900Nexus + no DJM-900Nexus Setting Utility coming up..

I typically have no problem doing this and recording via USB + Audacity on my MacBook, but since this issue just started happening, Audacity won't even record (although the Nexus input/outputs DO APPEAR in Audacity)

can anyone help resolve this issue?


THANK YOU ALL FOR YOUR HELP AND PATIENCE .. you guys are literally the best!
