Many mac users continuously face issues with Adobe Flash Plugin. This is because the Adobe Flash Plugin goes out of date, when an update is pushed by Adobe and specially Safari blocks the sites that require’s Adobe Flash to run. One of the most common example of such a site is YouTube. Other browsers that gets affected by the update are Firefox. If you are using Chrome, then you don’t need to update Flash Player as it is built into Chrome. The major trouble most users face when installing Flash Player is not the player itself, but the password which they have usually forgotten and is needed to permit Adobe Flash to install itself.
In order to update Adobe Flash Plugin you will need to download it and install it.
To do this, go to http://get.adobe.com/flashplayer 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.
