OS X 10.9 Mavericks, Chrome and Java

UPDATE: As of version 39, Chrome is now 64-bit! You can now simply download the latest version of Java and install. No more having to re-enable older versions of Java.

After upgrading to Mavericks I noticed that Java was no longer present on my system. Java-based applications such as PyCharm would no longer run and browser-based applets would display a plugin missing error in both Safari and Chrome. To get up and running again, two installs needed to happen.

First was the runtime. You can download Java for OS X 2013-005 directly or the OS will automatically download and install it if you launch a Java-based application such as PyCharm.

Once installed, $ java -version returns 1.6.0_65:

The second step was to install Java 7 from Oracle. Unfortunately this version of Java is only compatible with 64-bit browsers such as Safari. To use Chrome (still 32-bit), you must then disable Java 7 and re-enable the Apple-provided Java SE 6 web plug-in by following these simple steps.
