Profile Manager, part of macOS Server (now integrated into macOS as a standalone service), is a tool that allows IT administrators to create, edit, and distribute configuration profiles for macOS, iOS, and iPadOS devices. These profiles define settings and restrictions that can be deployed via MDM or manually. Apple Configurator (option A) is primarily for iOS/iPadOS/tvOS device supervision and configuration, not profile creation for macOS. System Preferences (option C) is a user-facing settings app, not a profile creation tool. Terminal (option D) can be used for scripting but isn't designed for profile creation. The Apple Platform Deployment Guide identifies Profile Manager as the macOS tool for this purpose.
