If with Itunes happens one of the following:
- You are unable to complete a purchase from the iTunes Store.
- You cannot play music you purchased from the iTunes Store.
- An alert appears with the following text:
“There was an error storing your authorization information on this computer. The required directory was not found or has a permission error.“
A missing Shared folder may prevent purchases from the iTunes Store or may prevent playback of purchased music. The following steps will recreate a missing Share folder using either the Finder or the Terminal.
Use the Finder
- Log in using an administrator account.
- From the Go menu, choose Go to Folder.
- Type: “/Users” and click Go.
- If there is not a Shared folder in the Users folder, from the File menu, choose New Folder.
- Name the folder “Shared”.
- Select the new folder and from the File menu, choose Get Info.
- Click the disclosure triangle to open the Ownership and Permissions section of the Info window.
- Set the permissions as follows (you may be prompted to enter an administrator account password):
- Owner: access Read & Write
- Group: access Read & Write
- Others: access Read & Write
- Close the Get Info window.
Advanced: Use Terminal
- Open Terminal (/Applications/Utilities).Warning: This step involves modifying permission settings by entering commands in the Terminal application. Users unfamiliar with Terminal and UNIX-like environments should proceed with caution. The entry of incorrect commands may result in data loss or unusable system software. Improper alteration of permissions can result in reduced system security or exposure of private data.
- Type: sudo mkdir -p /Users/Shared
- Press Return.
- Enter your administrator account password when prompted, then press Return.
- Type sudo chmod 777 /Users/Shared
- Press Return.
- Quit Terminal.
