Do you need to install a missing plug-in with Mac OS X? Your Mac will inform you of a missing plug-in, such as the Java plug-in, should the content you have encountered in your browser require one. In such instances, you will see Missing Plug-in display in the browser window in the area where the content requires it.
The Missing Plug-in prompt may also display if you have an outdated version of the plug-in, allowing you to update your Mac with the latest version. To view the content, you will need to install the missing plug-in. Below we show you how to install missing plug-in with Mac OS X. Also included is information about how to use the Security pane of Safari’s preferences to configure how you want individual websites to handle plug-in content.
1. Click on the icon in the web page. A notification dialog will display letting you know which plug-in is required to view the content.
2. To dismiss the dialog, click OK. To proceed with installing the missing plug-in, which is Java in this case, click the More Info… button. Once you have clicked More Info…, you will be directed to the appropriate web site to download and install the missing plug-in. You may also download, install and update Java for Mac OS X directly from the Java.com web site if needed. Please note that your Java Version may be different than pictured.
3. Click Agree and Start Free Download, and a download icon will display in the tool bar area of your browser. You can click the download icon to view the download progress.
4. Once completely downloaded, double-click on the box icon that displays in the notification window to start the installation process.
5. When prompted to Open the installation file, click the Open button.
6. If prompted to type a Username and Password for your Mac, input it, then click Install Helper to proceed.
7. The Installer will launch. Click Next to proceed.
8. You may be prompted to install a third-party search app. If you do not want to install the third-party search app, uncheck both check boxes. Click Next to proceed.
9. The installation will begin. A progress bar will display in the installation dialog to let you know the status.
10. A notification dialog will display when the installation has completed successfully. Click the Close button.
11. To verify your Java installation, visit the Java web site. If prompted to Activate Java, click the Activate Java link in the web page.
You may also see an address bar notification asking you to allow the web site you are visiting to run “Java”.
Click Allow Now to run Java one time, or click Allow and Remember to run Java any time the site is visited. When the Do you want to run this application? dialog displays, click the Run button.
The Java content will load in the web page…finally! The verification process will inform you that you have the recommend Java version installed on your Mac, accompanied by the Java version.
13. To configure Plug-in Settings in Safari on Mac OS X, click Safari > Preferences. Click the Security icon in the Preferences dialog. In Security settings, click the Plug-in Setting button.
14. A list of installed plug-ins displays next to a separate list of currently open websites (and currently configured sites, if any). Choose a plug-in, then highlight a website in the list. Use the pull-down menu to select Ask, Block, Allow or Always Allow as the plug-in’s security preference for that site.
