For more information, see JRE 7 Installation for Mac OS X. Under Oracle Java, only a single version of the JRE can be installed at a time. One of the functions of Java Preferences was to set the current version of the JRE. Therefore, OS X releases from Apple that do not include Apple Java will not include Java Preferences. Q: What happened to the Java Preferences app in Application -> Utilities?Ī: The Java Preferences app was part of Apple Java installation and is not used by Oracle Java.

For more information on creating an app that satisfies these requirements, see Packaging a Java App for Distribution on a Mac. To create a Java application that will launch without interruption under the default Gatekeeper settings, the app must be bundled with a JRE, use Oracle's launcher stub, and be signed with an Apple Developer ID. To override this, you can modify Gatekeeper's default settings, or explicitly right/control-click the application and choose Open. When you attempt to launch an app that doesn't meet certain criteria, Gatekeeper will block the launch. What is going on?Ī: Gatekeeper, introduced in Mountain Lion (OS X 10.8), is designed to prevent potentially malicious apps from launching.

(The hidden question inside this question is what version / source of Java I should select if I can depend on Apple to keep Java secure.) I understand 'safeness' is a fairly difficult thing to define, but just some general advice would be greatly appreciated. See also the following documentation for Java Web.
