Nov 16, 2017 Managing Java versions on Mac OSX is a nightmare. I recently switched over to using JDK 1.7, deleting JDK 6 from my MacBook entirely (I also had traces of JDK 5 – this laptop has been updated a few times). I nuked everything Java, JDK, and oracle. I was running Java 8 on OSX El Capitan. Other answers were missing tons of stuff. Jun 09, 2015 Hey, spent the day with El Capitan and have it running pretty well, one project was to rid my 2009 iMac of Java. I did all the usual things that are posted all over the web but am left with this pop up alert at startup and at other seemingly random moments it also appears. There are certain.
Java is no longer installed with a OS X 10.11 El Capitan clean install, and you’ll find that after updating a Mac a prior version of JRE may no longer function.
You may come across when trying to use some particular applications or web content, “This application requires the legacy Java SE 6 runtime which is unavailable for this version of OS X.” error message, which means if you want to run that app you’re going to need to use an older version of Java. P4v client.
If you do not need Java, you should not install Java. Java is, and always has been, the source of many security holes.
Here’s how you can install JRE (Java Runtime Environment).
Step 1. Open Safari and go to the Oracle Java downloads page and download the JRE .tar.gz version. You should end up with a file named something similar to jre-8u65-macosx-x64.tar.gz.
Step 2. Go to your Downloads folder and extract the JRE download or use Terminal to extract files:
Step 3. Open Terminal
Step 4. Edit the Info.plist file within to enable the JRE to be used from the the command line, and from bundled applications:
Step 5. Move the JRE folder to the correct location:
Type password on prompt.
Be sure you are in the correct directory (the JRE folder) when you issue this command, because it will move your current directory to /Library/Java/JavaVirtualMachines/!
Step 6. Create a link to add backwards compatibility for some applications made for older Java versions:
You should be done now, so try and open the application. If it does not work, some applications require legacy Java 6 to be installed.
You can have it installed without actually using it, however, it’s possible to trick the applications into thinking legacy Java 6 is installed, without actually doing so.
Step 1.Disable SIP (System Integrity Protection) in OS X El Capitan. Here is tutorial to disable and enable SIP.
Step 2. Trick some applications into thinking that legacy Java 6 is installed by creating two folders with the following commands in Terminal:
Install Java Jdk Mac
Step 3. Don’t forget to enable SIP again after creating these directories.
