Problem in executing example1.mod

Hi guys,

I’m new to Dynare and I’m facing an issue in running the first example mod file (“example1.mod”). I’m using Matlab version R2019b and Dynare 4.5.7. on a MacBook Pro with macOS Catalina installed (version 10.15).

I’ve followed step by step the instructions for the quick start at

In particular, I’ve installed Dynare, configured MATLAB for Dynare and created a new working director with example1.mod copied in it. Then, I changed the working directory in Matlab and I selected the one just created. However, when I run example1.mod, I get the following error message displayed:

Do you have any suggestion to fix this issue? Thank you in advance for your help.


@HoutanBastani Another Catalina problem

Hi @niccat

Unfortunately no. Dynare 4.5.7 was created before Catalina and Matlab R2019b came out and hence is not guaranteed to work with them.

The options are either to downgrade your system or to compile locally.
