The problems launching STEM seem to be
caused by a MacOS issue (after security update) with the version of the
Equinox Launcher used by STEM. The bug is not in STEM itself. The fix
may require a major build update but we are investigating.
Meanwhile Mac Users should use the following
1) Open a Terminal Window
2) Type Java -version and make sure
yoru are running Java8
3) cd into the directory that includes
the STEM executable (this is inside of the STEM.app container):
STEM will launch and run fine.
As soon as we have a fix we will release
a new build with working launcher but for now please use this command line
procedure from a terminal window to launch STEM on OSx
