Updated 09 Feb 2017 Mac Issues:  Errors after carrying out Java Liveupdate Grey Login Screen / Fail at Licence Screen

Checking in the Mac Console under Terminal / Java / Version, may state that the latest version of Java is installed.  However, in a small number of cases this has proved to be corrupted.


The FIX  is similar to that described above. Download the latest version of Java from Mac Support, reinstall and then reboot the computer.
