Itunes on start up disc
Morning,
i hope some one can help me my son has moved my itunes onto my start up disc. This means that my Mac Book pro keeps saying that my start updisc is nearly full and is restricting my iphone back ups and various other functions. Can somebody please help/advise me how to move it back to its orginial place without recommending a back up.
Thank you
