Correct Answer. A. Check under System Preferences > Sharing The hostname of a macOS device can be found under System Preferences > Sharing. This area provides system identification settings, including the device's hostname, which can be easily accessed and modified if necessary.
Option B is incorrect because going to Apple Menu > About This Mac > System Report primarily provides detailed information about hardware and system software, not the hostname directly.
Option C is incorrect because typing "hostname" in Spotlight searches for files, folders, and applications with that name rather than displaying the system's hostname.
Option D is incorrect because navigating to System Preferences > Network > Advanced provides network settings and configurations but not the hostname directly.
