Troubleshooting installing in /Applications/Dynare
In versions prior to 5.5, the macOS pkg installer required administrative rights to install Dynare, this is no longer the case. However, if you aim to install Dynare in /Applications/Dynare, you will need to modify the ownership of this folder. To do this, execute the following command in Terminal.app:
sudo chown -R $USER:staff /Applications/Dynare
Alternatively, install Dynare in a different folder or simply delete (or move) /Applications/Dynare before installing Dynare.
