Mac Pro does not find external CD ROM when it is plugged in. fix?
Mac Pro is not finding my external CD/DVD/ROM when I plug it in. I've tried both USB ports. These ports are working with my iPhone. I have done the Sierra update recently. I have tried restarting my laptop with the ROM plugged in and without it being plugged in. Nothing seems to work. How do I find my plug and play CD/DVD/ROM?
