Note if you use the Chrome browser, this could cause very few websites (those which use java) to stop working. More information about how to install and uninstall Java on a Mac can be found on.

If you're upgrading from an earlier Java version you may have to uninstall it before.

Web method: Test which version of Java you have online (only work if you use the Java browser plugin which is not recommended for security reasons).

Java HotSpot (TM ) 64-Bit Server VM (build 24.0-b56, mixed mode ) Java (TM ) SE Runtime Environment (build 1.7.0_40-b43 ) Ideally the output would look like this (in this example it is Java version 7):

Terminal method: Open a terminal and type: java -version.

Good news: At least the current 64-bit offline installer (only this was tested) for Oracle's Java 8 seems to not contain crap software.

However, then you need to manually check for new Java versions (important if you use the browser plugin/extension).

Maybe you would also want to disable the 'java update checker' since this will add a new auto start-up item (one of those things which slows down start-up times very slightly).

It is also a good idea to not install the browser plugin or disable 'web content' afterwards in the Java settings (see above for more info).

Download the installer from or pick 'JRE' at if you want to use a new, not yet mainstream, version.

You also could disable the browser plugin afterwards or use your browser's controls to disable or enable. They are not needed for running Java desktop programs (like the OSM editor JOSM) but frequently pose a security risk. If you are not interested in running applets inside the web browser you might choose not to install any browser plugins/extensions.
