How to authorize a computer if the previous apple ID is no longer active?
I just transferred to a new Macbook Air from an old 2009 Pro. I used migration assistant to transfer my info and iTunes needs me to authorize this computer to play songs that were in my sister's old library- that Apple ID is no longer in use though. Is there any way around this??
MacBook Air, OS X Yosemite (10.10.4)
