I am having the HDD on my iMac replaced and because of the demand, I will not have the computer for a couple of days minimum and a maximum of 5 days. I will still have my wife's iMac and my MBP, and this is where my question will be. Since I have my iTunes library on an external HD, could I just connect that HD to my MBP and share the library that way instead of relying on my iMac?
