However, if you wish to serve sites from within one of those locations, you will need to give Nginx "Full Disk Access". Otherwise, you may encounter server errors or other unpredictable behavior from Nginx, especially when serving static assets. Typically, macOS will automatically prompt you to grant Nginx full access to these locations. Or, you may do so manually via System Preferences > Security & Privacy > Privacy and selecting Full Disk Access. Next, enable any nginx entries in the main window pane.
