Java (Security) For Mac OS XJava for Mac OS X
Java is a programming language that allows application/software to run on different operating systems (e.g. Mac OS X, Windows, Linux, Solaris) as long as a Java Runtime Environment (RE) is installed on the target operating system. Java can also be found on web sites where "applet" code downloaded from the web site server will run locally on your computer via a web browser plug-in. There are different installations of Java depending on your usage requirement e.g. general user, developer, etc. The most common installation is the Standard Edition (SE) which is for general users.
Because Java runs applications in the OS and in web browsers it is a common attack vector for malware and viruses.
Java should not be confused with JavaScript which is a completely separate/different scripting language used on web sites/the internet.
Java is now owned and maintained by Oracle.
As of the 4th March 2015 (Java 8 Update 40) Oracle is now bundling
with their Java installer.
In the past (Java RE v6 and earlier) Apple used to get the Java code from Oracle and write a Java Runtime Environment (RE) for Mac OS X themselves but as of 15th October 2013 this is no longer the case. Java on a Mac consists of two primary software components:
An internet plug-in used to run Java "applets" via the internet in a web browser e.g. some banking web sites.
A "Runtime Environment" (RE) that also allows you to run Java "applications" directly within the operating system.
Java RE versions supported by Mac OS X
OS X 10.12 -
OS X 10.7 to 10.11 - , v7 or v6
Mac OS X 10.6 - Java RE v6
Mac OS X 10.5 or earlier - Java RE v5
Java v8 is currently supported and updated with security updates
Java v7 was end of life January 2015 and will no longer be updated after April 2015
Java v6 was end of life February 2013 and no more updates were issued as of 15th October 2013
Java v5 is no longer updated
Q. Which version of Java do you recommend?
A. If you don't need Java don't install it. If Java is installed we now highly recommend installing Java RE v8 from Oracle as Apple phased out Java RE v6 support in October 2012 and Oracle phased out Java RE v7 support in January 2015. So if you are running:
Mac OS X 10.6 or earlier = don't use Java and .
OS X 10.7 to 10.11 = (if you require Java) install
from Oracle.
Q. How can I tell which version of macOS / OS X / Mac OS X I am running?
A. Go to Apple menu (top left) > About This Mac > check the version reported for macOS / OS X / Mac OS X.
Q. How can I tell if a Java RE is installed on my Macintosh?
A. Follow these steps:
Go to Apple menu > System Preferences > Java
(if a Java Preference pane exists you have Java RE v7 or later installed - you can get information on the version installed by going to the General tab and clicking "About…")
If you do not have a Java Preference pane go to Macintosh HD > Applications > Utilities > Terminal
Enter the following commmand:
sudo /usr/libexec/java_home
Enter your computer's administrator password
NOTE: This Terminal command will report any versions of Java RE v6 or earlier that are installed on your computer. If none are listed you do not have Java installed.
Q. How do I keep Java RE v6 up to date on OS X (if it is installed)?
A. The last update produced by Apple is Java RE v6 v1.6.0_65 (available for OS X 10.7 to 10.11 as . Java RE v6 is no longer supported - if you have Mac OS X 10.6 or earlier . If you have
from Oracle.
Q. I have Java RE v7. How do I update it to v8?
A. Go to Apple menu > System Preferences > Java > Update tab and tick "Check for Updates Automatically".
See also this
article from Oracle.
As of the 20th January 2015 Java auto-update will update Java RE v7 to v8.
Q. Now that Oracle have released Java RE v8 is v7 end of life/insecure?
Q. Which versions of Java are no longer supported/insecure?
A. Oracle provides a . You can check the dates that Java RE versions become end of life/no longer supported/insecure but basically:
Java v8 is currently supported and updated with security updates
Java v7 was end of life January 2015 and will no longer be updated after April 2015
Java v6 was end of life February 2013 and no more updates were issued as of 15th October 2013
Java v5 is no longer updated
Q. I need Java and I've installed Java RE v7/v8 but my Java software specifically needs RE v6. Is there anything I can do?
A. Yes, you can downgrade v7/v8 to v6 by following the instructions in this
to disable Java RE v7 and re-enable Java RE v6 (but note that Java RE v6 is no longer supported for security updates so only do this if you absolutely must for Java compatibility).
Java Notes
For security reasons users of Mac OS X 10.6 with Apple's Java Update 9 or later will find that the Java plug-in deactivates automatically when no applets are run for an extended period of time. Java applets can be re-enabled by clicking the region labeled "Inactive plug-in" on a web page but as Java RE v6 is no longer supported or security updates you should only do this if absolutely required.
For security reasons users of
with Apple's latest Java update installed (Java Update ) will find this update uninstalls the Apple-provided Java applet plug-in from all web browsers. To use applets on a web page, click on the region labeled "Missing plug-in" to . This update also removes the Java Preferences application (from Applications > Utilities), which is no longer required to configure applet settings.
support Java RE v6 and v7 but both are now end of life so you should install
from Oracle.
Java was included as standard with Mac OS X 10.6 or earlier - it cannot easily be removed but it can be .
A Java RE is not included as standard with
but it does include a Java plug-in (so you are recommended to
if you don't use Java on the internet). A Java RE can be automatically installed by OS X (permission will be asked first - it is not a silent install) if you try to run any Java software on your computer (this automatic install is currently Java RE v6 from Apple but this is end of life so ultimately you should really install
manually from Oracle (if you require Java). In fact, Apple's Java Update
or later now actively pushes you to install Java RE v8 from Oracle anyway.
Java RE v6 is required for some old software applications such as .
If you upgrade the OS X operating system Java RE v6 is removed and needs to be reinstalled.

Java Bundled Adware
As of the 4th March 2015 (Java 8 Update 40) Oracle is now bundling adware with their Java installer! Initially it was
but currently it is Yahoo.
Adware is a search App/toolbar (browser extension) that gets added to your web browser by installing Java.
It is an optional installation but it is opt-out i.e. by default it will be installed - you have to explicitly tell the installer not to install it (see picture below).
Only new/clean installations of Java will give the option - however, full OS X system upgrades/clean installs may require Java to be reinstalled so this is a problem to also look out for when migrating computers or reinstalling/upgrading your OS.
If you already have a version of Java 8 earlier than Update 40 installed, the adware is not installed and the option to install it does not appear.
If you are installing Java 8 new/cleanly then you will get the below option screen during the installation process - to not install the Yahoo adware UNTICK "Set Yahoo as your homepage and new tab page on all browsers, plus get Yahoo as your default search engine on Firefox.":
adware screen looked like this - to not install
adware UNTICK " as my browser homepage":
How To Disable/Remove The Adware Installation Option
Once Java is installed, you can turn off the option appearing in future installations/updates by going to Apple menu > System Preferences > Java (this will open the Java Control Panel separately) > Advanced tab > scroll to the bottom and TICK "Suppress sponsor offers when installing or updating Java" > click "Apply" (see the picture below).
How To Disable/Remove
Adware On A Mac
Apple Safari Browser
Quit all running applications except Safari.
In Safari go to the Safari menu > Preferences > Extensions and turn the Ask extension off.
Mozilla Firefox Browser
Quit all running applications except Firefox.
In Firefox go to the Tools menu > Add-ons > click Extensions on the left > locate the Ask extension on the right and click the "Disable" or "Remove" button next to it.
