I am having problems burning CDs with the new iMac under Yosemite 10.10.5. WL 8.5
Have just replaced my iMac and the new one of course has no CD burner. I have tried 2 USB drives, one of them the hideously expensive Apple USB CD/DVD burner and get “an error has occurred, operation aborted” message around to 2 out of 3 burns. Never previously had a problem with the builtin drive.
Any pointers as to how to resolve this issue. As an audio engineer who produces two or 3 CDs a week, this is quite a problem.
