In newer versions of OS X  especially Yosemite  EL Capitan   Apple has removed Java support for security reasons  To fix this you have to do the following    Download Java for OS X 2015-001 from this link  https   support apple com kb dl1572 locale en US Mount the disk image file and install Java 6 runtime for OS X   After this you should not be seeing any of the below messages   - Unable to find any JVMs matching version   null    - No Java runtime present  try --request to install   This should resolve the issue for the pop-up shown below

I didn t need the full JDK  I just needed to make JRE work and none of the other answers provided above worked for me   Maybe it used to work  but now  1st Jul 2018  it isn t working  I just kept getting the error and the pop-up   I eventually solved this issue by placing the following JAVA HOME export in    bash profile   export JAVA HOME  Library Internet  Plug-Ins JavaAppletPlugin plugin Contents Home   Hope this helps someone  I m running Mac OS High Sierra
