Hi tedd57,
Thanks for reaching out in Apple Support Communities. I understand that you're having trouble signing in to iTunes on your Mac and iTunes is having trouble acquiring album information for content you're importing from a CD. I know how important using iTunes to manage your music collection is; I'd like to help. Regarding the trouble you're having signing in, if you haven't already, quit iTunes and restart your Mac. After restarting, verify your Mac is connected to the internet and try to sign in to iTunes again.
If the issue persists, use these steps to start your Mac in safe mode and try to sign in again:
To start up in safe mode:
- Start or restart your Mac, then immediately press and hold the Shift key. The Apple logo appears on your display. If you don't see the Apple logo, learn what to do.
- Release the Shift key when you see the login window. If your startup disk is encrypted with FileVault, you might be asked to log in twice: once to unlock the startup disk, and again to log in to the Finder.
To leave safe mode, restart your Mac without pressing any keys during startup.
If an issue doesn't happen when your Mac is started in safe mode, try restarting without pressing any keys.
- If the issue comes back, you might have incompatible login items.
- If the issue doesn't come back, it was probably caused by a cache or directory issue with your startup disk, which safe mode fixed."
Use safe mode to isolate issues with your Mac
If you can sign in, restart your Mac normally and verify that you're signed in iTunes again. If you're still unable to sign in, can you let me know what happens when you try? If you see an error message, what does it say?

Best Regards.
