I upgraded my mac to use an SSD for System and Applications and moved Users to a second HDD. iTunes will not allow me to authorize.

Here are my paths:

/Mac/... (System, etc)


Currently permissions on Pig are 755 system:wheel on /Pig, /Pig/Users, and /Pig/Users/Shared.

Error on starting iTunes:

You do not have enough access privileges for this operation

Error on authorization attempt:

There was an error storing your authorization information on this computer.

The required directory was not found or has a permissions error. Correct this permissions problem and try again, or deauthorize this computer if the permissions cannot be changed.

This computer was previously authorized. I've deauthorized everything in my account so now we're starting zero. I've also followed the Apple Support Article regarding this issue. http://support.apple.com/kb/TS1277?viewlocale=en_US&locale=en_US

I understand the gist of what's going on here, I'm just not sure how permissions need to be set up on the second HDD to accommodate iTunes.


  • Need more information to correctly diagnose what's going on. For example, do you get an error when you try to authorize? Also, how many computers/users have you authorized with that specific Apple ID?

Here's the deal w/ iTunes in regards to moving your Users directory to a separate drive or partition; it turns out that the Shared directory must remain on the system drive. For example, in my context the path should be /Mac/Users/Shared where 'Mac' is my system drive. The other users stay in /Volumes/Pig/Users/..., i.e., arrow and wildcat.

I believe the permissions I listed above are incorrect and they've since been changed to:

/Volumes/Pig - 644 system:admin

/Volumes/Pig/Users - 644 system:admin

/Mac/Users/Shared - 777 arrow:admin

Correcting the permissions to their current settings didn't solve the problem on it's own, moving Shared to the same drive as the iTunes binary did.
