- Oracle and Apple are NOT providing Mac Java updates in a timely manner. This Java update for Mac provides an update that Windows users have had for months. For over a week, there has been an active malware exploit against Mac users with the unpatched version of Java. It is terrific that Apple jumped on this exploit so quickly.

System Requirements
Observe the following requirements:
- Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.
- Administrator privileges.
Starting with JDK 7 update 6 Oracle provides a JRE version for Mac OS X users which includes a Java Plugin. The download is available in our main Java SE download page. Oracle does not provide version of the JRE below Java SE 7. For earlier versions of Java SE for Mac please contact Apple Computer.
Note that installing the JDK on OS X is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.
Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version as described in 'Uninstalling the JRE'.
JDK Installation Instructions
When you install the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.

Determining the Default Version of the JDK
If you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'.
There can be multiple JDKs installed on a system, as many as you wish.
When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.
You can determine which version of the JDK is the default by typing
java -version
in a Terminal window. If the installed version is 8u6, you will see a string that includes the text 1.8.0_06. For example:To run a different version of Java, either specify the full path, or use the
java_home
tool:For more information, see the java_home(1) man page.
Uninstalling the JDK
To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.
For example, to uninstall 8u6:
Do not attempt to uninstall Java by removing the Java tools from
/usr/bin
. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.I had a recent customer, ask a question on a website I make supplemental income, as a computer technician. This platform has the ability for us technicians to provide remote support. However, their integrated remote support software requires Java, for customers that use Apple Macintosh operating systems.

This customer was using an Apple Macintosh and was having difficulty installing Java. Below are detailed instructions on how you can install Java on your Apple Macintosh computer. Do you happen to know what version of MAC OS X is installed?
I checked Java.com and you would need MAC OS X 10.7.3 or newer. You can find out what version of MAC operating system is installed by clicking on the Apple icon and choosing “About this MAC”. Also, you could try to just download and install Java for Apple Macintosh from this direct Java download for MAC link.

Macintosh OS 10.7.3 is also referred to as Macintosh OS X Lion. This individual was able to successfully install Java from the download link I provided. Now they were able to obtain remote support from one of the technicians available.
I am NOT a big fan of Oracle’s Java. However, quite a few applications require it. Also, there is some confusion as to how and where to obtain this software.
I went directly to Oracle’s Java websites’ downloads section and found out that at the time of this blog post creation, you must have Apple Macintosh 10.7.3 or newer installed. There could still be a few Apple Macintosh computers with older OS X operating systems installed. You could possibly find an older archived version of Java to download or install.

Also, you could try to upgrade your Macintosh OS X operating system to a newer version that will support Java. Java run time environment is used in applications ranging from games to remote technical support.
