Troubleshooting Java on a Mac

If Java integration with Safari or Firefox stops working, you may need to reinstall or update your Java plug-in.

 To check for Java updates

1. Click the icon in the top left corner of your screen and click Software Update in the menu.
2. Once the search for available updates has finished, click Show Details to review the list for any Java updates. If none is found, you already have the most recent update and only need to reinstall Java.

To reinstall Java on your Mac

1. Click the magnifying glass icon in the top right corner of your screen to open Spotlight.
2. Type Terminal and press Return. You can also open the Applications folder, then open the Utilities folder and double-click Terminal.
3. In the Terminal window, type java -version and press Return. You will then see your Java version number, which may look like 1.6.0_20. Write down this Java version number for later use.
4. Click the icon in the top left corner of your screen and click About This Mac in the menu.
5. In the new window, you see a version number for Mac OS X, such as 10.6.4 or something similar. Write down this Mac version number for later use.
6. Open your web browser (such as Safari or Firefox) and go to http://support.apple.com/downloads.
7. In the Search Downloads field, type Java and the version number that was displayed in your Terminal window and press Return. For example, you might search for Java 1.6.0_20.
8. In the search results, look for the latest Java update for your version of Mac OS X. For example, you might look for search results like Java for Mac OS X 10.6 Update 2.
9. After you find the necessary update, click Download. Then install the update by double-clicking the file in the Downloads window.
10. Reboot your Mac computer if prompted to do so.
