iTunes says computer not authorized. When I try to authorize computer it says it is already authorized but will not play song. Note. Library was moved from PC to MAC. I am signed in to Itunes with the Apple ID created on the old computer which is different than the Apple ID used to set up the MAC.
I was able to solve the problem, simply by deleting the offending song, quitting iTunes and then reopening iTunes and re-downloading the song.
Prior to that I tried the "create SC folder" solution - no effect. Also, I repaired permissions in Disk Utility; funny thing is that there was a lot of errors related to iTunes that were fixed, but that did not cure the problem.
So if it's an isolated item that's been purchased from the store (or I imagine, matched via iTunes Match), then deleting it and re-downloading it should prove to be the cure.
I had only two songs off an album that this was happening with, so I tried what you said and it worked for me. Thank you!
