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 :-)

For what it's worth, I found that the Amazon Music Helper app was refusing to quit and prevented me from reinstalling over the app. Activity Monitor revealed that the helper was housed in the app itself. I deleted that and was able to reinstall the newest version.

This may not be much of an answer, but I have also had issues with 3rd party apps while using a MacBook Pro. Here are a couple things you could try:

1. Make sure the application is capable of running on your Mac version. [E.g; if your computer can handle 32bit applications or 64bit] Check Amazon's website where you downloaded the application to see if they have different versions. Alien Skin has an article on how to make an application run 32bit, if it's supported by the app.

2. Is your computer running the right OS X? [The app may only support 10.9 and above or something specific like that.] Again, check Amazon to see if they have specific versions of the app. - Find the OS X version and build information on your Mac

3. Check if the app is in the Mac App Store. [The App Store version might open without difficulties.]

This is an old enough question the answer might now be to download the most recent installer from Amazon (currently at this URL) and run that.

That is, the newer installer seems a bit more mature about edge cases and partial installs.

Longer version:

I was installing with a local copy of an older installer (from 2018) which caused the same issues when I didn't grant it whatever accessibility permission it wanted.

Reinstalls were no good, no matter what I deleted.

Downloading the most recent installer from Amazon (currently at this URL) did the trick.
