Where can I find installation files like libraries and solar and wind resource data on my Mac?
On a Mac, the files SAM uses are stored in the SAM package. To see the files, open a new Finder window, and go to the SAM package (it may be in the Applications folder, or somewhere else), control-click the SAM icon, and then choose Show Package Contents from the shortcut menu. Then, expand the Contents list to see the libraries, solar_resource, and wind_resource folders.
Best regards,
Paul.
