Problems with Dynare 4.5.4

Dear all,
I installed Dynare 4.5.4 in macOS but it does not read and run .mod files from any folder. However, it run and read .m files. My Dynare version is 4.5.4 and Matlab version is R2018a. Can some one help me on that. Thank you in advance.
Best regards

Which OS version are you using? And what is the error message? @HoutanBastani Do you have an idea?

Thank you for your replay. I am using macOS high Sierra version. My problem is solved. If I found any question I will let you know.
