Beta Big Sur kindle problems.

I just tried to open my Kindle and the display is unreadable and frozen...Evidently this is not a one off seems like quite a few people are having this issue.

Big Tech too worried about how to censor free speech than to fix this crap! Amazon busy screwing over Parler. Put out crappy apps and make us live with it. They in charge now.

I have Big Sur on a MacBook Air. When I open Kindle, I can open a book but it crashes about 30 seconds later, no matter which book. Restarted computer, deleted and re-downloaded app. Same problem. Apple people, please help.

This has been going on for months since the initial release of Big Sur but zero response from anyone and now I have thousands of dollars of books I cannot access.

Yeah this has been going on for months now. I can't even access my books needed for uni, and cannot get an answer.

My wife is having the same issue. Apple says “not our problem “... really. Why did I buy her an expensive Mac laptop. She has 900 Kindle books.

BACKUP! BACKUP! BACKUP!

I NEVER install a beta or new OS upgrade without a complete backup. If you do not have one, buy a 2TB portable external and run a complete backup before you install. I learned that lesson 30 years ago and I only did that once. Lost everything.

Then, unmount the drive and stick in a drawer before you install. If it's necessary, then you can wipe the drive and start over with a clean install from your backup.

You need to uninstall the app and then delete select files in the library and elsewhere (then reinstall and it will work). This website page will walk you through it: goodereader.com/blog/kindle/what-to-do-if-the-kindle-app-for-mac-does-not-work-on-big-sur

This problem was making me bonkers (I need to read on the laptop for school). Good luck!

Same here. When I turned my Mac. on it told me to delete the Kindle app because it would damage my Mac. and was from an unknown developer. I tried opening a new Japanese cook book I got. It opened. As I was going through the pages, it crashed. Actually, it just went away. Then I got something telling me I could notify Apple.

It is odd.

I just upgraded. I was like two operating systems back. But before I did I got two external drives from WD. One 4 and the other 5 tb. I backed everything up. Which took hours. Then I installed the OS I had been using on the other drive. So I can just run the OS from that drive I guess.

I did as @chocolatevamp has suggested above.It has solved the problem of selecting text crash.As for some kind of mobi file,it just crashed without any hint.

Had same problem with Kindle app on iMac. Did an normal "uninstall" with CleanMyMac X, and redownloaded, and OK now...

Même chose pour moi. A chaque fois que j'ouvre l'application Kindle et que j'essaie d'ouvrir un livre, elle plante.
Le service client d'amazon n'a pas pu faire grand chose pour moi : il m'a demandé de supprimer l'application et de réinstaller l'application plusieurs fois mais le résultat est le même. Kindle est inutilisable pour l'instant ce qui est un problème.

So I've run into this same issue, where the Kinder Reader App is extremely slow. I cannot zoom and focus on a page without taking 30 seconds to deal with the lag.

I'm almost sure this is an issue from Apple requiring (forcing) the move from OpenGL, to Metal. I say this, because any app not using Metal experienced a huge slow-down after the update (due to the limited OpenGL core). Looking at the version history of the Reader app, that seems to be the case as there are no mentions of any framework updates since El Capitan.

Anyways...

The only resolve I've found is to stop using the official MacOS app. I often use to iOS reader anyways, but when I want to use the laptop, the Kindle Cloud Reader works well, even though it's limited in the feature department. 😞 https://read.amazon.com/

We can only hope that Amazon updates the app in the near future. 🤞
