steinberg UR44 audio interface wont work if you have the lastest MacOS HIGH SIERRA on your macbook. Apple did put more privacy filters for the content you download from the web. the interface comes with a cd with supposedly the lastest version of yamaha USB drives. this is false, it is not the lastest version. if you installed already what came im the cd unistall it inmediately and re intall it but from the steinberg internet page. once you do that your mac will ask you to allow the hardware and software on your mac. problem solved. i spent some good 5 hours trying to fix this flashing power light. THANKS FOR THE HEADACHE STEINBERG.
