I have a mac mini 2010 model with snow leopard. I use the mac mini ONLY in my recording studio and just to record music with garageband. I have an external hard drive I want to hook up to the mac mini so I can store my music on it and now use up all my internal hard drive space. Can someone PLEASE explain to me how to format the external hard drive to my mac mini AND also explain how to store the music on the external hard drive? THanks and God bless!!
