View, comment, download and edit ejercito Minecraft skins. How To Uninstall Java From El Capitan Java is one of the most confusing and frustrating add-ons for Mac and here we show you the easiest way to uninstall Java from El Capitan. The truth is, theres actually no way to fully remove Java from Mac but you can easily completely disable it.

OS X El Capitan and Java: No Fun (till now!)

There's been a bunch of stuff on the interwebs lately about El Capitan and Java issues... here's the simple simple, condensed version of the fix:

Quick prereq to the post:

I have, for some time, had the following line in ~/.bash_profile under my login on my machine:
I see it this way... /System/Library/Frameworks/JavaVM.framework/ relies on a set of symlinks that, in turn, rely on /Library/Java/Home being another symlink that points to the Home directory of an installed JVM. Changing the /Library/Java/Home symlink ensures that all of that other machinery (legacy or otherwise) continues to work correctly.
At the very least with this setup typing 'java -version' at the command line gives me the version I'm looking for. And swapping symlinks to point to real disk locations is fairly easy... it makes it MUCH easier to change JVM versions. Just repoint the symlink to
/Library/Java/JavaVirtualMachines/{jvm_folder}/Contents/Home
and Bob's your uncle... it's done. And no other changes necessary.
So I selected to base this all on /Library/Java/Home being The Correct Location For The Current JVM.
As I said... the above line is in a file called .bash_profile under /Users/{username}. If you have to create it be sure that afterward you open terminal and run
cd ~
chmod u+x .bash_profile
and then restart terminal. That will ensure that JAVA_HOME is always set when you hit Terminal. This makes many things lots easier, but most of all, since most Java packages will check for JAVA_HOME and only go looking for a JVM if not set, it gives you control over the Java version being used to run whatever it is you are trying to run.

So...

That's why I chose to set JAVA_HOME to /Library/Java/Home and proceed as I have.

Download and install Legacy Java 6SE from Apple:

Download and install Java 8 JDK from Oracle:

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Change a system symlink to make the Java 8 JVM the command line default:

cd `echo $JAVA_HOME`
sudo rm Home
sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home ./Home

Once done, test with the following command on the command line:

java -version
If you've done the above correctly your Java apps will launch and your command-line tools (oh, like launching Tomcat) will automatically use the latest JVM.

OH, also... once you've installed the Java 8 JDK you may have to do two other things:

Edit the Java JDK PLIST

Edit the file at /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Info.plist to be:
<key>JVMCapabilities</key>
<array>
<string>CommandLine</string>
<string>JNI</string>
<string>BundledApp</string>
</array>

Add a symlink to point to libserver.dylib

It seems the Oracle installer doesn't create a necessary symlink for the JDK, so you'll need to copy/paste the following commands (there's 2 of them, btw):

Java Se 6 For El Capitan


sudo mkdir -p /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/bundle/Libraries
sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/jre/lib/server/libjvm.dylib /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/bundle/Libraries/libserver.dylib

Give thanks to Oliver from Australia!

Dude is my hero and this wouldn't have happened without his blog post. However he's missing the J2SE 6 install and download and has a bunch of other stuff in there that isn't really relevant anymore.

How do you downgrade Java version on MacOSX El Capitan? Right now when I run java -version I get:

java version '9.0.1' Java(TM) SE Runtime Environment (build 9.0.1+11) Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

I need to have it say:

java version '1.8.0_25' Java(TM) SE Runtime Environment (build 9.0.1+11) Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

So I can run a specific npm java based package.

I tried following instructions on Java website for uninstall/re-install with no luck. They suggest to run these 3 commands:

Doing this seems to do nothing. When I run java -version I still get the same result.

I watched this video But I cannot find the JavaAppletPlugin.plugin referenced in video.

What am I doing wrong? How do you change Java version on El Capitan Mac OS?

Look at SDKMAN - http://sdkman.io/

Java for el capitan

You install it, then do sdk list java

You can install any or all of these, and select whichever one you want to use and set a default, as well:
