Apple - Amazon Music app won't launch

I just experienced the same symptoms. I resolved it by deleting ~/Library/Application Support/Amazon Music. The only file in that directory was a file called i18nUpgrade.txt with the contents Upgrade to i18n build.

I had the same issue on my new Macbook Air (replacing an older Macbook Pro), with the same Console message.

Deleting the app and reinstalling had no effect, and deleting ~/Library/Application Support/Amazon Music had no effect.

What eventually worked was to delete / uninstall with AppCleaner and reinstall. The files that AppCleaner identified:

  • /Applications/Amazon
  • ~/Library/Application Support/Amazon Music
  • ~/Library/LaunchAgents/
  • ~/Library/Preferences/

Deleting i18nUpgrade.txt didn't solve my issue. So I've deleted the entire ~/Library/Application Support/Amazon Music folder! And ... da da da ... Amazon Music starts and ask for login data :-)
