Why does my Kindle app on Mac crash every time I open a book?
You should restart your Mac. Restarting the device is probably your best bet if you’re having software-related issues.
You should also update your Mac’s operating system to the most recent version. Similarly, you should be using the most current version of Kindle for Mac to avoid glitches. You may easily update to the most recent version with a single click from the Amazon page.
If nothing else works, simply remove Kindle for Mac and reinstall it.
