As developers working on macOS applications, we’ve frequently run into situations where we needed to quickly back up an application’s settings (preferences) and Core Data object store information. Then the hunt for the appropriate files ensued. Where does macOS store this information again? Oh, and the location depends on whether the application uses sandboxing or not.
We solved this problem by creating an app that located the appropriate files and allows the user to quickly and safely back them up as well as restore them.
