SuperDrive not seen on 2 devices.
My late 2011 MacBook Pro, macOS 10.13.6, NEVER sees my new Apple SuperDrive. No icon on desktop, not listed under Devices on Finder sidebar. Plus when plugged into a USB port cannot insert any disc.
This happens intermittently also when attached to my iMac.
Have moved the plug to different USB ports on either computer. Last time that I was able to see the SuperDrive on my iMac & could load a disk heard an unhealthy clunking noise as the disc spun; unable to view or hear any discs and it was difficult ejecting the disc: had to restart the computer a couple of times before Super Drive would cough it up. ???
