Apple Music
In Apple Music (iTunes) I need to deauthorize a computer no longer belonging to me that I no longer have access to. I cannot 'deauthorize all' because I have already done that once this year and it won't let me do it again until January next year. (How crazy is that?) Apple Music tells me I have 2 computers authorised but there seems to be no way of finding out their identities. So how can I deauthorize the computer that I no longer have access to? This seems like a ridiculous situation and I can't understand why Apple make this so difficult.
