I am pissed off.Amazon's Kindle for PC is a free e-book software reader and manager for Windows. Apple and Amazon have gone to far with their controlling users. 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. Would you trust Apple and Amazon now? I live on SSI/SNAP due to disabilities am born with. 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. And on sep.15th the app on my iMac will no longer work at all anymore. 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. 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. You can easily download and install the latest version of the Kindle for Mac from our download page on Amazon. 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.
