This tutorial is only intended for users running the Safari Web browser on OS X and macOS Sierra operating systems.

In the Safari browser, plug-ins can be installed to add functionality and enhance the power of the application. Some, such as basic Java plug-ins, may come prepackaged with Safari while others are installed by you. A list of the plug-ins that have been installed, along with descriptions and MIME type information for each, is maintained locally on your computer in HTML format.

This list can be viewed from within your browser in just a few short steps.

Difficulty: Easy

Time Required: 1 Minute

Here's How:

  1. Open your browser by clicking on the Safari icon in the dock.
  2. Click on Help in your browser menu, located at the top of the screen.
  3. A drop-down menu will now appear. Choose the option labeled Installed Plug-ins.
  4. A new browser tab will now open containing detailed information on all of the plug-ins you currently have installed including name, version, source file, MIME type associations, descriptions, and extensions.

Manage Plug-ins:

Now that we've showed you how to view which plug-ins are installed, let's take things further by walking through the steps needed to modify permissions associated with said plug-ins.

  1. Click on Safari in your browser menu, located at the top of the screen.
  2. When the drop-down menu appears, click on the option labeled Preferences.
  3. Safari's Preferences interface should now be displayed, overlaying your main browser window. Click on the Security icon.
  1. Located at the bottom of Safari's Security Preferences is the Internet plug-ins section, containing a check box that dictates whether or not plug-ins are allowed to run within your browser. This setting is enabled by default. To prevent all plug-ins from running, click on this setting once to remove the check mark.
  1. Also found within this section is a button labeled Plug-in Settings. Click on this button.
  2. All active plug-ins should now be listed, along with each website currently open within Safari. To control how each plug-in interacts with an individual website, select the respective drop-down menu and choose from one of the following options: Ask, Block, Allow (default), Allow Always, and Run in Unsafe Mode (only recommended for advanced users).
