In order to update Adobe Flash Plugin you will need to download it and install it.
To do this, go to https://get.adobe.com/reader/flashplayer/about/index.html and download the Flash Plugin. After it has been downloaded, open it and run it and click “Install Adobe Flash Player”
If prompted by a message saying “Install Adobe Flash Player is an application downloaded from the internet. Are you sure you want to open it“, click Open.
You will then be prompted to input your OS X Password, type in your password and click OK to proceed. If there is no password, just click OK. If there is a password and you’ve forgotten it, then you’ll need to reset password before proceeding, see steps at how to reset mac password. After the password has been resetted, you can begin with the installation using the new password.
The next window may indicate that the “Installation will begin shortly” wait for it. If prompted by an option to choose how updates are managed, then chose “Allow adobe to install updates (recommended)” and click Next. Flash player will begin download and the installation automatically.
After installation has finished, Click Finish – and reboot your browser, if you still get the blocked plug-in message, then the chances are that the website you are visiting requires an older version of Flash. This is common with online gaming websites, unfortunately, downgrading to an older version is a security risk and is not recommended. However, what you can do is to use Google Chrome to play games instead of Safari until the website has updated their games/programs to work with the latest flash update.
