iTunes says computer not authorized. When I try to authorize computer it says it is already authorized but will not play song

I spent many days on the phone and sending emails back and forth with Apple and they could never resolve it.

see my reply. Apple support will fix this at no cost.

When I try to authorize computer it says it is already authorized but will not play song.

Doublechecking. Are you getting that message for every purchased item that you've moved across to the Mac? Or just one particular song?

Every m4p purchase.

🙂 Many thanks.

With that, let's try the following two documents:

iTunes repeatedly prompts to authorize computer to play iTunes Store purchases

iTunes: Missing folder or incorrect permissions may prevent authorization

I have the same problem. All my purchased Music works but not any Shows. It keeps saying authorize this computer even though it already is. SERIOUSLY spent MONTHS working on this with Apple Tech and iTunes Tech and the Genius Bar and they could never resolve it. So every Video file bought does not work.

i have the same problem now ?

Has anyone figured out how to fix this?

Out of the blue, my MacBook is repeatedly prompting that I need to authorize the computer to play my iTunes songs. The computer is authorized (no question about that).

Even worse, now I can't sync my music onto my iPhone.

Please Help!!!

Same issue suddenly appearing with slightly different angle:

I have multipe countries itunes accounts (e.g UK and US). yesterday I downloaded a song fromthe UK account (actually I redeemed a freebee card from Starbucks in the UK account)

I have never had this problem before and have loads of songs and movies from 3 different countries on my Macbook pro

I'm having it also...................................

I also still have this problem...

I'm experiencing the same thing under iTunes 11.1.1:

1. iTunes says the computer is not authorized, prompts me to authorize
2. I enter my credentials, iTunes says computer is already authorized
3. When I attempt to play song, iTunes starts at bullet point 1 above over again.

My attempted fixes:

1. I tried everything in this support document, to no avail: http://support.apple.com/kb/TS1389 (Note: I cannot find a SC Info folder on my Mac)
2. Deauthorize and then reauthorize computer
3. Delete song and try to redownload from iTunes store - there's only a button that says 'purchased' with no option to redownload it

Note: I am using only one iTunes account, and I double checked the song info - I'm authorizing the correct account - 12 songs from the same album purchased at the same time play fine. As does the song in question - from the finder. Only iTunes stubbornly refuses to play it.

The most odd thing is that iTunes music is DRM free - the song in question was purchased only a few months ago. Thus there's no need to authorize the computer to play it.

I was hoping that iTunes 11.1.1 would cure it - no dice.

I found out that I had somehow created two accounts, and one had become compromised. I called Apple support, and they cheerfully fixed the problem. There was no charge involved; I guess support is free for purchased music not playing.

I have the same problem.

Started after the new iTunes and IOS updates. I have both iPhone and iPad, my iPad syncs just fine but the iPhone 4 stoped.

When I go to My Devices > Manage Devices, it only shows my iPad ( iPad lib)

before that update showed my two devices.

I did all things to add my iPhone again bot doesn work =/

I can't sync my APPs only

I did the same steps that mikuk did, except I was also able to find and delete my "/Users/Shared/SC info" directory. I still have the problem. An interesting fact, I have this problem on just two out of 3510 purchased tracks in my iTunes library. The two tracks are from separate albums. All of the other tracks on those albums are playable and can be downloaded to my iPod.
