That is, the object is reset and available to generate another MAC from the same key, if desired, via new calls to update and doFinal. (In order to reuse this Mac object with a different key, it must be reinitialized via a call to init(Key) or init(Key, AlgorithmParameterSpec). The MAC result is stored in output, starting at outOffset inclusive. Below is a direct link to install the Java 6 Runtime for for OS X 10.11 El Capitan, OS X 10.10 Yosemite, OS X 10.9 Mavericks, OS X 10.8 Mountain Lion, and OS X 10.7 Lion. Install Java for OS X 2015-001 here. The reason we are installing Java 6 from Apple website is that SUN did not come up with JDK 6 for MAC, so Apple created/modified its own deployment version. Similarly install JDK7 and JDK8. Add JDKs to jEnv. JDK 6: JDK 7: JDK 8: Check the java versions installed using jenv. So now we have 3 versions of Java on our system. The Java properties indicate the location of the jar file, the name of the Main class, and the version of the JRE to be used. The other properties include a pointer to the icon file and to the Java application stub file that is the native executable. Creating Mac OS X Java Applications on Other Platforms.

System Requirements
- Any Intel-based Mac running Mac OS X 10.7.3 (Lion) or later.
- Administrator privileges.
Note that installing the JDK on a Mac 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.
JDK 7 Installation Instructions
Installation of the 64-bit JDK on Mac Platforms
When you download 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.
Depending on your processor, the downloaded file has one of the following names:
- jdk-7u<version>-macosx-amd64.dmg
- jdk-7u<version>-macosx-x64.dmg
Where <version> is 6 or later.
1. Download the file. Before the file can be downloaded, you must accept the license agreement.
2. From either the Downloads window of the browser, or from the file browser, double click the .dmg file to launch it.

7. The software is installed and a confirmation window appears. Click the ReadMe for more information about the installation.
After the software is installed, delete the dmg file if you want to save disk space.
Determining the Default Version of the JDK
A: If you have not yet installed Apple's Java Mac 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 Macs 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 7u6, you will see a string that includes the text 1.7.0_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.
Navigate to /Library/Java/JavaVirtualMachines and remove the directory whose name matches the following format:*
For example, to uninstall 7u6:
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.
*The 7u4 and 7u5 releases were installed into a directory that does not follow this format. To uninstall 7u4 or 7u5, remove the 1.7.0.jdk directory from the same location.

You can find Java version on Mac without running a Java applet in your web browser. Fortunately, there are a variety of methods to find the Java version on Mac. Below is a description of some of those methods. Also see Java Support in Safari 12.
Using Command Line in Terminal
Terminal is a program included with macOS that provides command line access to the operating system. Terminal is located under Applications folder -> Utilities folder. To find the Java version using command line, launch the Terminal application. Type or copy/paste the following line into the Terminal window:
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version
The Java version will display as output in the Terminal window, and will look similar to the output below:
java version '1.8.0_40'
Java(TM) SE Runtime Environment (build 1.8.0_40-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)
In this case, Java 8 Update 40 is the Java version installed on this Mac.
Using the Java Control Panel
You may find Java version on Mac using the Java Control Panel instead. For information about locating the Java Control Panel, please see the Where is the Mac Java Control Panel located article. Once you have launched the Java Control Panel, click the General tab.
In the section entitled About, click the About… button. A new About Java window will launch. Java version information will display within the window.
All Version Of Java For Macs
In this case, Java 8 Update 40 is the Java version installed on this Mac.
Using the Online Test Java Page
You may also test your Java online to determine which version of Java is installed on your Mac. To test Java on your Mac, visit the Test Java page provided by Oracle on its Java.comweb site. This utility will not only check your current Java installation, but will also remove old Java versions from your computer that may pose a security threat to your system. If your Java is working correctly, and no out-of-date Java versions are found, you will see the following notification accompanied by information about your Java installation and your computer:
Java For Mac
As it states in the Verified Java Version web page, Java 8 Update 40 is installed on this Mac. If your Java is not working properly, the Test Java page displays additional configuration options that you may need to check, as well as download and installation instructions if needed.
