Hi - recently bought a new iMac (exciting times as my previous one was rather old!) however went to load a cd into iTunes and duh! No cd/dvd drive! Which accessory do people recommend? The Apple one gets terrible reviews for being expensive and very slow. I don’t want to spend a fortune as I only use it occasionally for loading cds (don’t laugh - I know I’m old school!) and maybe burning cd/DVDs. Really appreciate your advice.
