Would like to share an email I got from Amazon a few days ago:Dear ??????It's time to update your Kindle for Mac app! We appreciate the time you've spent reading with our Kindle for Mac app, but you have registered a version on one of your computers that is out of date and scheduled to be retired by September 15. Our latest update (version 1.11.0 or above) is still free, and includes important bug fixes that are required to continue using the app. You can easily download and install the latest version of the Kindle for Mac from our download page on Amazon. You can check the Kindle version number by choosing 'Kindle' from the menu of your app and then selecting 'About Kindle.' Please see our troubleshooting pages for Kindle for Mac if you have any other questions.Thanks for reading with Kindle!Sincerely, The Amazon Kindle Team-I called Amazon about this. Senior Amazon support staff explained that Apple requested Amazon force all Mac kindle users to upgrade to the 10.10 before they can use the latest Kindle app. And on sep.15th the app on my iMac will no longer work at all anymore. So content I have in my Amazon account is forever locked up out of my use until I upgrade my Os and the Kindle app. Would you trust Apple and Amazon now? I live on SSI/SNAP due to disabilities am born with. I cannot afford to buy a new mac let along pay for upgrading all my apps just to run on 10.10 on my 4yr old iMac. Apple and Amazon have gone to far with their controlling users. Please share and pass on this warning. I am pissed off.
