Apples’s latest Java “update”, Java for OS X 2012-006, disabled Java 6 for use with Java Web Start and mandates a transition to 64-bit Java 7.
Users of OS 10.7 and later must:
- perform a software update to get the latest changes from Apple
- open Safari and download Java 7 from http://java.com/download
The latest updates from Apple and Java are required to use the the synchronized browsing feature.
After updating to Java 7, flash content may no longer be shown in the embedded browser due to increased security.
Also, following the upgrade to Java 7, the recording feature will be unavailable. Unfortunately, Apple removed the mp4 encoding capability in the 64-bit interface. Recording may be accomplished with a 3rd party application like Camtasia.
