External Email - Use Caution        

One error in the logs is from missing symbols in the Matlab java library, and another says to contact the Mathworks for technical support.  But Mathworks is not going to support you because MacOS 10.13 does not meet the system requirements for R2014b.

You don’t have to upgrade to MacOS 10.14 or 10.15 to run R2019b per MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/support/sysreq/files/system-requirements-release-2019b-macintosh.pdf
- but the oldest version of MacOS you can run with R2019b is *exactly* MacOS 10.13.6 and not an earlier version.  You should be able to use the MacOS software update tool to update to 10.13.6 if you are not already running it. I recommend that as I believe that is the last/most stable version of MacOS 10.13.   From the compatibility chart, MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://www.mathworks.com/support/requirements/previous-releases.html, it looks like you could also try the older R2017b release.  I think you tried R2019b before with the freesurfer 7.3.2 release but not with the 7.2.0 release which you are now running.

You can follow the same instructions below to install R2019b or R2017b with the fs_install_mcr script and see if you get different results.  You should only have one ./freesurfer/MCR* subdir present at any one time.   It’s not clear to me the java libraries included in the Mathworks runtime environment care about the version of Java installed in MacOS, e.g., if it is 1.7 or 1.8.  The errors would seem to indicate the system version of Java is not the issue.
