What about error code 50?

Hello there, DREW1264!

Thanks for reaching out to the Apple Support Communities! I know how important it is to be able to find information about errors and resolve the issue. The good news is there is an article that has steps for error 50: Find an iTunes error code. When you click on 50, it will take you to another article: If you see ‘There was an error downloading your purchased music‘ when you try to download music from iTunes:

When you try to download content you bought from the iTunes Store, you might see a message that says "There was an error downloading your purchased music. An unknown error occurred."

To fix the issue, check for any issues with third-party security software, then remove the cached download file and try to download the music again.

Fix issues with third-party security software

If your connection times out while your music is downloading, you might see this message. The time out might be caused by security software monitoring certain servers and common ports. If your third-party security software doesn't let you download from iTunes, learn how to fix the issue.

Remove the cached download file

A network issue can also cause an iTunes download to time out. When this happens, a cached download file might not let you download the file next time. Remove the cached download on a Mac or PC before you try downloading again.

On a Mac

1. If iTunes is open, quit the program.
2. In Finder, select Go > Home from the menu bar at the top of your computer screen.
3. Open Music > iTunes > iTunes Media. If you have an older iTunes library, you might see an iTunes Music folder instead of an iTunes Media folder.
4. Open Downloads.
5. Drag all files from the folder to Trash.
6. Open iTunes.
7. From the menu bar at the top of your computer screen, choose Store > Check for Available Downloads.
8. If prompted, enter your Apple ID and password.
9. Click Check. Your music downloads to your iTunes Library.

Cheers and have a great day!
