How to enable Java with Mac

Update: Please see Java support in Safari 12 for information about viewing Java content with macOS. The information conveyed in the article below is no longer supported on your Mac.

Some web sites contain Java content that requires a Java Runtime Environment (JRE) to view. If your Mac does not have JRE, you may see a missing plug-in notification instead of the content itself. This usually means your Mac does not have Java enabled, or does not have Java installed. Also see Java support in Safari 12.

Before you can enable Java with Mac, you may need to verify and download it first. If Java is not enabled by default after you download and install it on your Mac, it might need to be manually enabled. To do so, launch the Java Control Panel on your Mac (Apple menu > System Preferences > Java).

Double-click the Java icon in System Preferences. The Java Control Panel will launch in a separate window.

In the Java Control Panel, click the Security tab. Check the Enable Java content in the browser check box, and click OK to save your edit.

So the change takes effect, close all your open web browser windows. In a new browser window, visit the web page with Java content to see if it displays.

Certain web browsers, such as Google Chrome, will block Java content from displaying by default. If you are trying to view a web page with Java content on your Mac using Chrome, try an alternate web browser like Safari or Firefox. If you have no choice but to use Chrome, you can view Java content within the Chrome wrapper using the IE Tab extension. IE Tab uses the Internet Explorer rendering engine so you can view Java content in Chrome. It allows you view ActiveX and Silverlight content too. IE Tab is easy to install, and even easier to use, keeping in mind that it only works on Windows.
