If you’re finding that the Kindle For Mac app won’t open anymore, the solution is usually a case of reinstalling it via the Mac App Store. Sometimes after an update to macOS, you may find that the Kindle app bounces in the Dock for a few seconds and then disappears without opening. Or you may get the following “Kindle quit unexpectedly” error message:
The solution is simply to fully delete the Kindle app from your Dock and then reinstall Kindle for Mac from the Mac App Store. Don’t worry – you won’t lose your library of books or documents as they will be re-synced as soon as you sign-in again with your Amazon account.
Just follow these instructions to fix Kindle For Mac if it’s stopped opening or not working:
1. Drag the Kindle icon in your Dock to the Trash bin situated on the far right of the Dock. Hold down the Ctrl key, click on the Trash and select Empty Trash.
2. Then simply re-download Kindle For Mac from the Mac App Store.
If for any reason you can’t access the App Store, you can also download Kindle directly from Amazon. You just have to enter your email address on the Amazon Kindle Download Page and Amazon will send you link so you can directly download the latest version of Kindle on your Mac.
