If you try to run an Adobe CS6 or CS5 application (Photoshop, Illustrator, InDesign, etc.) on OS X Yosemite or later, you will most likely encounter a problem. After double-clicking on some Adobe applications, a message will appear informing you that you need to install the old Java SE 6 runtime environment to open the application.

In addition to the Adobe CS5 and CS6 software packages, other applications require the Java SE 6 runtime (Eclipse, PDF Studio 9, FileMaker Pro Advanced, Patch Tool, Dreamweaver, and even the popular Minecraft game).

This problem occurs because these applications (Adobe CS5, CS5, etc.) are based on Java 6. Mac OS X Yosemite (and later versions) have a newer version of Java Runtime (SE 8.0). However, the Java Runtime is not backwards compatible. Thus, even if the operating system has installed Java Runtime 8, NO application that relies on Java Runtime 6 will work.
