My previous post about installing Java on OS X received quite a bit of traffic, and I felt that some of the information was outdated, and it became a little unclear after all the edits, so I’ve endeavoured to create a much easier to understand set of instructions.

The instructions for installing the JDK (Java Development Kit) are a subset of the instructions for installing just the JRE, because Oracle provides an installer for the JDK.

1. Go to the Oracle Java downloads page and download the JDK installer. You should end up with a file named something similar to jdk-8u60-macosx-x64.dmg, but perhaps a newer version.
2. Open the .dmg Disk Image and run the installer.
3. Open Terminal
4. Edit the JDK’s newly installed Info.plist file to enable the included JRE to be used from the the command line, and from bundled applications:

   The third line fixes a permissions issue create by using defaults write. The fourth line is not required, but makes the file more user-friendly if you open it again in a text editor.

5. Create a link to add backwards compatibility for some applications made for older Java versions:
6. Optional: If you’re actually using the JDK for software development, you may want to set the JAVA_HOME environment variable. The recommended way is to use /usr/libexec/java_home program, so I recommend setting JAVA_HOME in your .bash_profile like Jared suggests:

   This will get the latest installed Java’s home directory by default, but check out man java_home for ways to easily get other Java home directories.
   

You should be done now, so try and open the application. If it does not work, some applications require legacy Java 6 to be installed. You can have it installed without actually using it, however, it’s possible to trick the applications into thinking legacy Java 6 is installed, without actually doing so.

Jdk 10_osx X64_bin Dmg Free

If you’re running El Capitan, this is actually a little difficult now, because Apple added SIP (System Integrity Protection) to OS X. I have written a post explaining how to disable and enable SIP.

Java Jdk X64

If you’ve disabled SIP, or are not running El Capitan yet, you can trick some applications into thinking legacy Java 6 is installed by creating two folders with the following commands in Terminal:

Jdk 10_osx X64_bin Dmg 1

Don’t forget to enable SIP again after creating these directories.
