I downloaded my cd's to my macbook pro and transferred them to my Iphone and I want to take it off the mac and keep it on the phone is this possible? If not how can I download my cd collection to my iphone? Because I have only 11 GB left on my mac.
Keep in mind once on the iPhone you cannot transfer the music back to the computer. So make sure to put the music onto an external HDD or something so you don't have to reimport all the cds to the computer
Just a bit of clarification... Third party apps like "iMazing 2" and others allow moving music, videos, iBooks, and other items back on to your Mac or PC. However, you are correct that it can not be done with just iTunes.
