My iMac (mid-2011) has a CD/DVD drive which I have not used
How do I use it? Where to find instructions? I see "System Preferences" has a button for CDs and DVDs. But I don't know what all the choices mean. I also gather Apple stopped including this hardware in subsequent iMacs.
The technical specs for this are as follows, but this does not mean a whole lot to me.
