Issue with nemesis and Catalina OS


I am trying to run Pylith on a new machine with Catalina OS. I have been able to install pylith just fine (see screenshot), but whenever I try to run one of the examples I get an error message from Catalina blocking nemesis. I have allowed my mac to access petsc but for nemesis it did not offer the option to overrun the third party app warning. This may be something beyond the pylith developers and more of a department IT question but I thought it’d be worth posting here to see if anyone else has dealt with this issue.



There is a lot of good discussion here about getting around the Catalina security settings:

I disabled all that on my Catalina since I cannot deal with Apple’s dogmatic attitude.
