I am sorry to disturb you. when I run the Dynare, I get the following message: “Warning: Matrix is close to singular or badly scaled. Results may be inaccurate”. However, I can get the estimation results without any errors. I have searched related topics. Some said it can be ignored, while others advise changing the initial value of parameters. Thus, my questions are:
Under what conditions can the warning be ignored?
How can I set the “proper” initial value?
By the way, when I update Dynare to 5.0, I get the message “Installation error The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.” Why I cannot update Dynare above 4.6.4 on my Macbook? Is it because I haven’t updated the operating system？

It very much depends on where that message appears. In your case it happens when trying to compute the unconditional variance of the states for the Kalman filter. That is rather unusual. Why do you specify diffuse_filter although the model does not have unit roots? Have you tried whether the problem also appears in a simpler version of your model?
Each Dynare version is compatible with a particular macOS unless you build it from source. But without the log-file it is impossible to tell why the installation failed.
Do you mean I should simplify my model to find out the reason? Could you please give me some possible reasons and how to solve these problems?
After viewing the log-file, I find that it is not able to connect to github.com. I have updated to Dynare 5.2 by skipping to install use_dll option. How does use_dll option affect the operation of Dynare？
