I'd just like to know if I can use an external CD drive for reading and burning with a 2011 MBP OS X 10.9.5. I haven't bought and connected a new one yet but there doesn't seem to be an option in iTunes to use something other than the internal drive. It's got more difficult to persuade the internal drive to accept a CD and now it's impossible. Tried resetting PRAM and SMC, and it won't accept a CD cleaner. Thanks.
