• How to fix this application requires the legacy Java SE 6 runtime which is unavailable for this version of the OS XIf anyone is using the beta version of El.
• Since I upgraded my Mac to OS X El Capitan (version 10.11.2) I am having problems with the R-package rJava. From what I understood, eventually, it is not a problem of rJava or R or RStudio in the first place, but newer versions of Mac OS X do not play well with the latest versions of Oracle’s Java (jdk). Furthermore, some new security.

Macs do not include Java by default so you have to download and install Java on El Capitan, Sierra and High Sierra separately. One of the most common problems users have after upgrading to El Capitan, Sierra or High Sierra is an error message when trying to access certain websites or run apps that require Java and this tutorial helps fix that. There are also issues regarding legacy support for Java 6 in macOS 10.12 Sierra which we clarify at the end of the article. Note that we don’t recommend you install Java unless absolutely essential because it’s notoriously unstable and insecure and once installed, you can’t ever fully uninstall Java from a Mac. However, if you’re one of those people that has no choice because the website you need to access, application you want to use or the game you want to play requires it, follow these instructions.

Java for macOS 2017-001 installs the legacy Java 6 runtime for macOS 10 13 High Sierra, macOS 10. You may recall from the days of OS X 10 7 Lion that Apple used to provide the Java 6 runtime.

How To Install Java On El Capitan, Sierra & High Sierra

If you’ve upgraded to El Capitan,macos Sierra or High Sierra and keep receiving the error message pop up:

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.

To use the “java” command line tool you need to install a Java SDK

It’s because an application you have installed or a website you’re trying to access requires Java to launch or work properly. If you’ve never installed Java on Mac, then you can simply download and install the latest version of Java from Oracle which is known as Java 8 but rather confusingly officially called Java 1.8 by Oracle.

If you’re not sure whether Java is installed on your Mac, simply search for Terminal in Spotlight and type: java -version at the command prompt.

If Java is on your Mac, you’ll see a message saying something like “Java (TM) Runtime Environment” in this case version 1.6 (or Java 6 as it is commonly known). If you find that you already have Java 1.6 installed, scroll down below “How to update Java 6 in El Capitan” as you also need to install a special update from Apple.

Java Installation Problems in El Capitan, Sierra & High Sierra

If you run into problems during the installation of Java, it’s because Apple has added an extra layer of security to Macs known as Rootless SIP. Java has such a bad rep on Macs that Apple has made it increasingly difficult to install it and other things that can potentially damage OS X. If your Mac is blocking the installation of Java, follow these instructions to disable rootless SIP and try again:

• Restart your Mac when the screen turns black hold down ⌘R until the Apple logo appears.
• Select the “Utilities” menu and then “Terminal”. In Terminal type: csrutil disable
• Hit Return and then restart OS X. Your Mac will then restart with SIP disabled and you can try installing Java again.
• To re-enable System Integrity Protection, follow exactly the same procedure except type: csrutil enable
• Rootless SIP is then renabled on your Mac.

Note: You will have to deactivate SIP when new updates for Java are released as Java will not update while SIP is enabled.

How To Update Java 6 On Mac

If you find that Java apps or applets will either refuse to run or open briefly before crashing giving you an error message such as “This application requires the legacy Java SE 6 runtime which is unavailable for this version of OS X”:

or the Java applet crashes with an error message such as:

com.apple.xpc.launchd[1]: (com.apple.xpc.launchd.oneshot.0x10000004.OSXJavaLauncher[395]) Service exited with abnormal code: 1

It’s because some applications, games and websites still only work with Java 6. Examples of people that may still need Java 6 are those trying to access some government sites, some online games and Android programmers that require Java 6 to develop Android apps on Mac. If you’re having problems running Java 6 on your Mac in El Capitan then you simply need to install Apple’s legacy Java 6 OS X 2015-001 update. This is a special update from Apple which allows the outdated Java 6 to safely run on your Mac. In the release notes for the Java 6 update, Apple states:

Java for OS X 2015-001 installs the legacy Java 6 runtime 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. This package is exclusively intended for support of legacy software and installs the same deprecated version of Java 6 included in the 2014-001 and 2013-005 releases.

To install the update, you must quit any Java applications that are running and then simply download and double click on the Jave 6 update file and the update will automatically install. If you run into problems during installation, you’ll need to disable Rootless SIP protection in OS X (see above). Note that Java 6 does not officially work with OS X 10.12 Sierra although some users have had success with it so it may work and it seems to depend on the specific app you need it for.

Note: Do not get Java confused with JavaScript! JavaScript is an essential component for most browsers that enables it to display certain elements properly and is completely different to Java despite the confusingly similar name. Disabling JavaScript will mean many websites simply won’t work in your web browser anymore.

Support For Java 6 In Sierra

The bad news for those that need Java 6 on macOS 10.12 Sierra is that it is no longer officially supported on anything higher than OS X 10.11 El Capitan. Due to various security and support issues, last year Apple announced plans to discontinue any support for Java 6 in future versions of OS X:

OS X v10.11 is the last major release of OS X that will support the previously deprecated Java 6 runtime and tools provided by Apple. Applications or features that depend upon Java 6 may not function properly or will not launch when Java 6 is removed. Developers should move to a newer version of Java as provided by Oracle.

However the Apple link that Oracle refers users to has now been removed by Apple leaving some doubt as to whether Apple has had a change of heart regarding support for Java 6 on Sierra. Some Mac users are reporting that you can still install Java 6 on Sierra and it works for some apps but not for others. In the case of Cyberduck for example, it seems that the developer has updated the app to work with Java 6 in Sierra so it may well be down to individual developers whether they force their apps to work with it. Our advice is don’t rely using Java 6 on Sierra until Apple clarify whether it will be officially supported. Java 7 and 8 are officially supported in OS X 10.12 Sierra and if you don’t need Java 6, we highly recommend updating to Java 7 or 8 because Java is notoriously insecure and older versions are particularly vulnerable to attack and bugs.

As stated in the introduction, if it’s not necessary to you, you’re better off not installing Java at all on your Mac as it’s an increasingly antiquated platform that often causes more problem’s than it’s worth. And you can never fully remove Java from a Mac although you can find instructions how to disable Java on your Mac here.

I would like to use the WatchService API as mentioned in this link:http://download.oracle.com/javase/tutorial/essential/io/notification.html

After reading around, I found out that WatchService is part of the NIO class which is scheduled for JDK 7. So, it is in beta form. It's fine.

http://jdk7.java.net/download.html has the JDK which I downloaded and extracted. I got a bunch of folders. I don't know what to do with them.

Then, I read around some more and found that some nice group of people created JDK 7 as a binary so someone like me can install it easily. It is called Open JDK:http://code.google.com/p/openjdk-osx-build/

So, I downloaded the .dmg file and install it. Then I open 'Java Preference' and see that OpenJDK7 is available.

So, now I feel that I can start trying out WatchService API. From the tutorial in the first link, the author gave a .java file to test it out first and make sure that it is running. Here is the link to the file:http://download.oracle.com/javase/tutorial/essential/io/examples/WatchDir.java

So, I boot up Eclipse (actually I use STS) and create a new Java project and choose JaveSE-1.7 in the 'use an execution environment JRE:'. Under the src folder, I copy pasted the WatchDir.java file.

And I still see tons of squiggly red lines. All the 'import.java.nio.*' are all red and I cannot run it as a Java app.

What do I need to do?

This is how I got 1.7 to work with Eclipse. I hope it helps.

1. I Downloaded the latest OpenJDK 1.7 universal (32/64 bits) JDKfrom Mac OS/X branch from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
2. copied the jdk to /Library/Java/JavaVirtualMachines/ next to thedefault 1.6.0 one
3. In Eclipse > Preferences > Java > Installed JREs you add a new one, of type MacOS X VM, and set the home as /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home andname Java SE 7 (OpenJDK)
4. Click Finish
5. Set the added JRE as default

that should be it :)

Years ago, Apple joined the OpenJDK project, transferring their formerly proprietary macOS-specific JVM code as free-of-cost open-source. Apple ceased distribution of their own branded JVM/JDK, relying on Oracle’s branded releases to include a version for macOS.

Oracle has recently announced their intention to bring their Oracle-branded JVM release to feature parity with the OpenJDK project, with virtually the same code base. The company even donated their previously commercial tools, Flight Recorder & Mission Control, to the OpenJDK project. This is part of the shift to a new rapid “release train” plan for predictably scheduled versioning of Java and OpenJDK. Notably, the periods for free-of-cost public updates is now shortened. See this 2017-09 announcement and this posting by Mark Reinhold.

As a result of all this, macOS users of Java have a choice of vendors for a Java implementation. At this point, at least three sources are based on OpenJDK for macOS:

• Oracle releases of the JDK and JRE, with optional paid support.
• Azul Systems releasing:
  • Zulu line of free-of-cost JVMs with optional paid support.
  • Zing line of commercial JVMs with special features such as an alternate garbage-collector.
• OpenJDK source code, roll-your-own compilation & installation (perhaps not practical for most of us).

Meanwhile, IBM donated code for a JVM to the Eclipse Foundation, now housed in the OpenJ9 project. I wonder if they might support a macOS release as well, though it is too soon to tell.

Personally, I am currently using the Zulu release of Java 10.0.1 from Azul on macOS High Sierra successfully with IntelliJ 2018.2 to produce Java-backed web apps with Vaadin.

Installation/Removal

Both Oracle and Azul provide utterly easy-to-use installers to install the JVM/JDK on your Mac. Verify your installation by using the Terminal.app (or equivalent) to type and run:

You will find the Java installations in this folder at the root level of your drive (not in your home folder):

/Library/Java/JavaVirtualMachines

Each version from each vendor is found there, in a labeled nested folder. You can delete any installation simply by deleting the nested folder for that version and providing your system password when prompted.

You can download the Java Development Kit (JDK) for Java 8 for the supported versions of Mac OS X:

• Mountain Lion (10.8.3+)
• Mavericks (10.9)
• Yosemite (10.10)
• El Capitan (10.11)

Each version of JVM you install can be found here:

For more instructions and FAQ, see this Oracle Guide.

For every release of Java 7 since Update 4, a Mac version has been ready alongside the other platforms. Runs on Macs with 64-bit hardware on Lion (10.7.3+), Mountain Lion (10.8.3+), and Mavericks (10.9.x).

Oracle announced the official release of the JDK for Java SE 7 Update 4 on Mac OS X (Lion), as of 2012-04-26. No more need for the tricks discussed on this page.

Installation is simple per these instructions:

Which Java Do I Download

1. Download from the usual place on the Oracle web site.
2. Mount the DMG.
3. Run the installer.

This release has a few limitations, most notably the lack of support for Java Web Start and the Java Plugin for web browsers. That support is expected later this year.

After installing, read the JDK for Mac ReadMe. Most importantly, if you want Java 7 to be the default, drag it to the top of the list in the Java Preferences app found in your Utilities folder.

Mac OS X easily supports multiple JVMs simultaneously. Each is now found here:

Congratulations to the Apple & Oracle teams for their achievement. This geek gets a thrill seeing Mac OS X listed as a 'Certified System Configuration'.

Tip: To start Eclipse on a Mac with only Java 7 installed, open the alias file named eclipse rather than the file named Eclipse.app.

Apple continues to supply an up-to-date implementation of Java 6 for all versions of Mac OS X up through Mountain Lion.

If you do something that requires Java, such as type 'java -version' in Terminal.app, a dialog appears offering to install Java for you. If you accept, installation happens automatically similar to other 'Software Updates' from Apple.

You will find Java installed in this location, different than Java 7 & 8:

Java 6 has reached end-of-life with Oracle as of 2013-02 (unless you have a commercial support agreement with Oracle). So you should be moving to Java 7 or 8.

In Terminal.app, type java -version to verify which version is the current default.

After installing a fresh version, you may want to visit the folder described above to delete old versions. Move the folder to the Trash, and provide your System password complete the move.

By the way, Apple provides a mailing list for developers’ technical issues related to Java on OS X.

An easy way to install Java 7 on a Mac is by using Homebrew, thanks to the Homebrew Cask plugin (which is now installed by default).

Run this command to install Java 7:

I know that some may want to smack me for re-opening old post, but if you feel so do it I just hope this may help someone else trying to set JDK 7 on Mac OS (using IntelliJ).

What I did to get this working on my machine is to:

• followed instructions on Oracle JDK7 Mac OS X Port for general installation
• in IntelliJ open/create new project so you can add new SDK (File > Project Structure)
• select Platform Settings > SDKs, press '+' (plus) sign to add new SDK
• select JSDK and navigate to /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home. Do not get it mistaken with /Users/YOUR_USERNAME/Library/Java/. This will link 4 JARs from 'lib' directory (dt.jar, jconsole.jar, sa-jdi.jar and tools.jar)
• you will need also add JARs from /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib (charsets.jar, jce.jar, JObjC.jar, jsse.jar, management-agent.jar, resources.jar and rt.jar)

Get cask

Install java7:

(I had difficulty finding the download link of java7 on oracle website, as they're just 'recommending' java8 )

EDIT January 2018(As pointed by Ankur):

Use zulu7 cask. Zulu is a certified build of OpenJDK produced by Azul Systems that should be around for a long time (they even offer JDK6 builds still).

It's possible that you still need to add the JDK into Eclipse (STS). Just because the JDK is on the system doesn't mean Eclipse knows where to find it.

Go to Preferences > Java > Installed JREs

If there is not an entry for the 1.7 JDK, add it. You'll have to point Eclipse to where you installed your 1.7 JDK.

If Eclipse can't find a JRE that is 1.7 compatible, I'm guessing that it just uses your default JRE, and that's probably still pointing at Java 1.6, which would be causing your red squiggly lines.

after installing the 1.7jdk from oracle, i changed my bash scripts to add:

and then running java -version showed the right version.

The instructions by peter_budo worked perfectly. I had to add the jars under /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib/ to my IntelliJ project libraries. Now it works like a charm. Note that I didn't need my IDE itself to run under 1.7; rather, I only needed to be able to compile and run against 1.7. I'll most likely continue to use Apple's JRE for running the IDE since it's probably more stable with respect to graphics routines (Swing, AWT). Like the OP, I was really keen on testing out the new NIO2 API. Looking good so far. Thanks, Peter.

What worked for me on Lion was installing the JDK7_u17 from Oracle, then editing ~/.bash_profile to include: export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home

As of December 2017, previously posted links don't work, but JDK 7 can still be downloaded from Oracle Archives (login required):

I updated to Yosemite and Android Studio wouldn't clean my projects or Run them on virtual or real device because of the following error:

After some research and trouble shooting, I found that the JDK file that was being pointed to at '/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home' wasn't there; all of 'JavaVirtualMachines/1.6.0.jdk/Contents/Home' was missing from '/System/Library/Java'. So, I copied 'JavaVirtualMachines/1.6.0.jdk/Contents/Home' over from '/Library/Java/' to '/System/Library/Java/' and cha ching! I was back in business.
