It may be faulty, but may I raise a few points which have nothing to do with that?ġ. I decided to invest(not much)in an external dvd drive but the iMac does not 'see'it when plugged into a usb port.The drive light comes on and there is some wirring of the disc inside but then nothing.There is no icon on my home screen or any indication of the presence of an external drive anywhere.I Googled the problem and someone suggested I alter one of the files called ''.Coud not edit it as I was informed by the Mac that I did not own it but could edit and save a duplicate which is what I did.Īt that point I thought I would stop and seek more expert advice from the forum to see if I am on the right track.The external drive is advertised as mac compatible.I am as far from a Mac expert as you can get so if there is an idiots guide to getting it working that would be great. I have an ageing iMac from 2010 running High Sierra.I do not use the internal dvd/cd drive very often but when I do it is very slow and when inserting a disc it grinds away and sounds as if it chewing up the disc before finally bringing up the disc menu.
