Once you click on one of the links above to download the necessary update for your system, you’ll be presented with a download screen. Just click the big yellow “Install now” button to start downloading the appropriate update, open the DMG file, click “Install Adobe Flash/AIR”, and restart whatever browser you’re using.

It’s really a shame to see Adobe Flash not dying off as quickly as it could, because right now, ass it is is a security flawed buggy mess that slows down any Mac on the planet (alongside any Windows or Android system, however it’s not as bad as on a Mac). Hopefully in the future, we’ll officially see the end of Flash and begin watching YouTube and Netflix with JavaScript or something.
