Application Compatibility Notes

Java™ Application Support — starting with OS X 10.7 in 2011, Apple stopped including a Java installer with OS X. This has not changed in El Capitan. For OS X applications that require Java 7 or later, please visit Oracle's Java page for OS X to get answers to common questions, as well as Java installer links. For applications that require Java 6, please use Apple's legacy Java installer.

The large majority of Mac OS X applications do not require Java, however there are some notable exceptions. According to Adobe's official system requirements pages, some legacy applications within the Adobe® Creative Suite® (CS) and Adobe® Creative Cloud® (CC) do require Java. Examples of Adobe (and other) applications that require Java include, but may not be limited to:

Dreamweaver® CC (2013);
Dreamweaver CS6;
Flash® Builder® 4.5 and earlier;
Flash® Professional CS6;
Illustrator® CS6 – may require Apple's Java 6 runtime

Other Developers:

Notes: None of the applications bundled with OWC or NewerTech products require Java. If you are not sure whether a specific OS X app requires Java (or which version it might require), please contact the developer directly. Also, according to Apple's developer notes, OS X El Capitan is the last major release of OS X that will support the Java 6 runtime; plan your future application upgrades accordingly.
