- The Java Preferences app was part of the Apple Java installation and is not used by Oracle Java. Therefore, macOS releases from Apple that do not include Apple Java will not include Java Preferences.
- Java SE 7 Update 6 marks Oracle’s first full JDK and JRE release on Mac OS X. All of the features and functionality available for other OSs are now available on Mac, including the JavaFX rich client platform. Java developers using Macs can download Oracle’s JDK for Mac OS X from the Oracle.
It also provides a step-by-step guide for creating, compiling, and executing a Java program using either DrJava or the Terminal. All of the software used is freely available. You will need an Intel-based Mac running Mac OS X 10.8 (Mountain Lion) to Mac OS X 10.13 (High Sierra). You can defer steps 4–6 until Section 1.5 of the textbook.
Since OS X 10.7 Java is not (pre-)installed anymore, let’s fix that. As I’m writing this, Java 11.0.4 is the latest version and AdoptOpenJDK is one of the best places to find Prebuilt OpenJDK Binaries. Easy to follow details about how to install OpenJDK are available here.
However, the easiest way is to select OpenJDK 11 (LTS), the HotSpot JVM, and macOS x64, which will expose two option like these:
Clicking on “Install JDK installer”, will download the OpenJDK installer package, e.g. OpenJDK11U-jdk_x64_mac_hotspot_11.0.4_11.pkg, which when executed, will install into this location: /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk
Almost done. After opening a terminal, the successful installation of the JDK can be confirmed like so:
… hopefully showing something like this:
JAVA_HOME is an important environment variable and it’s important to get it right. Here is a trick that allows me to keep the environment variable current, even after a Java Update was installed. In ~/.zshrc, I set the variable like so:
In previous macOS versions, this was done in ~/.bash_profile. Now it’s done.
The source code of the Java Platform, Standard Edition 11 Reference Implementations binaries is available under the GPLv2 in a single zip file.

If Java is not installed, you receive the following message: “To open “Java Preferences,' you need a Java runtime. Would you like to install one now?”
- Click Install and accept the license agreement. The Java runtime is downloaded and installed.
Many Adobe applications depend on the Oracle Java Runtime Environment (JRE) for some features to work. Apple recently changed the way it includes Java in Mac OS, and with Lion, Java is no longer preinstalled. It is now an optional install that you must select.
Since current Adobe installers and applications were built before these changes by Apple, Adobe software anticipates that Java is installed. Adobe and Apple have worked together to ensure that you can install Java at OS install time. Or it can be installed later before you install Adobe applications. At runtime, when you launch an Adobe application, you are prompted to install Java if it is not already installed. If you do not install Java before running an Adobe application, there can be missing or improperly behaving features. If you encounter any issues, install Java to correct the problems. Adobe recommends that corporate IT organizations pre install Java (or make sure that Java can be installed through their firewalls/security) to avoid conflicts with Adobe applications.
If the Java runtime is not installed, some issues that are known to occur include -
Update Java On Mac Os
- Failure to launch.
- Install Java runtime prompts when you attempt to use the applications.
- Applications hang or quit.
