Apple did stop shipping Java as of 10.7 and higher. Neither the JDK nor the JRE come preinstalled. However, the first time you need a JRE, Mac OS X will offer to download and install it for you (via the Software Update mechanism). Similarly, javac is stubbed in a base OS X install and will trigger the install process. Note that the Apple JRE/JDK is Java 1.6—if you need 1.7.

To log in, use your email address and password (or username and password if you have an older account ).

Q: How do I install Oracle Java?
A: See the JDK 7 and JRE 7 Installation Guide for the Mac.
Q: How do I install JavaFX?
A The JavaFX SDK and runtime are included in the installation of the JDK and JRE respectively, and they are integrated into the same directory structure. For information on how to work with JavaFX, see the JavaFX Documentation.
Q: Can I restore Apple Java 6 after uninstalling Oracle Java 7?
A: Go back to Apple Java 6 using the following instructions:
- Uninstall Oracle Java 7 by deleting the plug-in file. From a Terminal window enter:
- Create a symlink using the following command, entered on a single line:
Q: I am running Mountain Lion (OS X 10.8) or later and Gatekeeper is blocking an app from launching. What is going on?
A: Gatekeeper, introduced in Mountain Lion (OS X 10.8), is designed to prevent potentially malicious apps from launching. When you attempt to launch an app that doesn't meet certain criteria, Gatekeeper will block the launch. To override this, you can modify Gatekeeper's default settings, or explicitly right/control-click the application and choose Open.
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. For more information on creating an app that satisfies these requirements, see Packaging a Java App for Distribution on a Mac.
Q: What happened to the Java Preferences app in Application -> Utilities?
A: The Java Preferences app was part of Apple Java installation and is not used by Oracle Java. Therefore, OS X releases from Apple that do not include Apple Java will not include Java Preferences.
One of the functions of Java Preferences was to set the current version of the JRE. Under Oracle Java, only a single version of the JRE can be installed at a time. For more information, see JRE 7 Installation for Mac OS X.
To access the Java Control Panel, click the Java icon in the System Preferences panel. If the Java icon is not present (under the Other category) in System Preferences, you do not have an Oracle JRE installed.
Q: I have Oracle's version the JRE installed, but it is not listed in Java Preferences.
A: This is correct. The JRE will not show up in the Java Preferences list unless you install the full JDK.
Q: I have Oracle's version of the JRE installed, but when I try to use java from the command line, it does not work.
A: Installing a JRE from Oracle does not update java -version symlinks or add java to your path. For this functionality, you must install the full JDK.
After upgrading to a newer version of Mac OS X (Yosemite 10.10 and El Capitan 10.11) or macOS (Sierra 10.12 and High Sierra 10.13), you may end up getting an annoying new pop-up message whenever you start your computer. It says, “To use the java command-line tool, you need to install a JDK.” It asks you to click “More Info” and visit the JDK (Java Developer Kit) download website.
The reason you’re receiving this message is due to the removal of Java support in newer versions of OS X for security reasons. Older software such as Adobe Photoshop and Illustrator requires legacy Java support. Without a compatible Java command-line tool for these software, you’ll get this pop-up every time you turn on your Mac computer.
When you visit the download website to update Java, you find that the issue isn’t resolved! You’re still getting the same pop-up. This isn’t a complicated issue to fix, but it is an indirect one. The problem is that you’re not being routed to the correct download website when you click “More Info.”
Apple could have remedied this issue by programming the “More Info” button to direct you to the right fix. Here are the steps you can take to finally rid yourself of this pop-up:
Fix Java Command-Line Tool Pop-Up on Mac OS X
What Does Java Do For Mac Versions
- Download Java for OS X 2017-001 aka Apple’s version of Legacy Java Command-line tool.
- Mount the .dmg disk image file and install Java 6 runtime for OS X.
- Restart your Mac and enjoy the absence of this Java command-line tool error pop-up!
