Adobe Flash is used for certain content on websites-usually video or web apps. While it's slowly being phased out in favor of HTML5, occasionally a website still requires you to install the Flash player. Warning: Do not download Flash from anywhere except Adobe . It's a common phishing tactic for a malicious website to claim your Flash player is "out of date" and a direct download to you. You should only download Flash from Adobe's official download page.
Flash comes packaged in a DMG, and they have separate versions for different browsers. Choose the browser you are using, download Flash, and open it up. There should be a single installer to run, and all you can to do is to agree to the terms and conditions.  The Flash installer wants to ask you how you like the program to update-automatically, manually, or with a pop-up like most App Store apps use.
Updating Flash Manually
Flash wants to add a new preferences pane in the System Preferences, from where you can configure the local storage and camera settings, as well as manually check for updates. By clicking "Check Now."
If Flash is out of date, it will automatically download an up-to-date version, click "Check Now." Below "Updates," you will be able to reconfigure the options you selected when installing. to-date version.
Flash is configured properly in your browser, especially when security is concerned, because of running any random Flash app (usually found in malicious advertisements) you to malware. So we recommend enabling click-to-play, which just wants to run Flash apps that you manually approve.
