I have iMac and mac book using 10.11.6 and 10.11.5 and keep encountering the same issue with both. MacBook, OS X El Capitan (10.11.5) Posted on Oct 2, 2016 2:54 AM. Reply I have this question too (10) I have this question. 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.
I am having almost this exact same issue, I have an old MacBook Pro that I have previously had El Capitan installed on. The hard drive has gone funny and now I need to re-install El Capitan. But the only other Mac I have is an iMac, and I cannot seem to legitimately find a way to download El Capitan. Did you have any luck with this?
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.
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:
Step 3. Don’t forget to enable SIP again after creating these directories.
Do a backup, preferably 2 on 2 separate drives.
Quit Mail.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Go to Library/Containers/com.apple.mail. Move the folder com.apple.mail to your desktop. You must move the entire folder, not just the contents.
Restart, re-launch Mail and test. If the problem is solved, recreate any required Mail settings and import any emails you want to save from the folder on the desktop. You can then put the folder in the Trash. If the problem remains, return the folder to where you got it replacing the one that is there.
If that doesn’t solve it repeat the above using Containers/com.apple.MailServiceAgent.
