Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode) Java(TM) SE Runtime Environment (build 1.8.0_45-b14) You may need to update the version numbers to match the latest Java release. Note that the version referenced throughout this post (1.8.0_45) may not be current as you are reading this. The installation process is straight forward, and I confirmed Java SE 8 was installed correctly, but I still received the alert. I went to the Oracle Java downloads page and downloaded JDK 8 ( it is possible to install the JRE, but not with the installer provided by Oracle). I also created a new post with instructions for installing the JDK which is slightly simpler, but contains unnecessary files for users not doing Java software development. I’ve created a new post with instructions for installing just the JRE, which should be fine for most users. I did not want to install an old version of Java, but it turns out the latest release doesn’t work out of the box.Įl Capitan has been released, and some things have changed. MacApplication.I tried running an app that requires Java, but received an alert saying “you need a Java SE 6 runtime. Val macApplication = Application.getApplication The code is written in Scala, but it is easily translated to Java: The following code shows how to set up an AboutHandler. In short, the new approach is to use the following classes to handle the Mac OS X About, Preferences, and Quit menu items: I recently learned that Apple has deprecated the approach I’ve used for many years. Update for Mac OS X 10.9 (Mavericks), 10.10 (Yosemite) and newer Using the source code from a Java/Mac application I just created, let's look at how this works.

The key behind properly handling the About, Quit, and Preferences menu items and events comes from using Apple's Application and ApplicationAdapter classes.

The Mac Application and ApplicationAdapter classes For Java 9 and newer, see my new tutorial, How to enable About, Preferences, and Quit menu items on MacOS and Java 9 and Java 10. UPDATE: The technique shown below works on Java versions prior to Java 10. Fortunately doing this is very simple, and I'll demonstrate that in this 'Java on macOS' tutorial. When writing Java GUI code for the macOS platform (formerly Mac OS X), you'll want to properly handle the Mac About, Quit, and Preferences menu items and events.
