Enabling the ‘airplane mode’ feature on macOS disables all wireless communication. This includes Wi-Fi and Bluetooth connections. Functionally, it severs the Mac’s ability to transmit or receive radio frequency signals. This action prevents interference with aircraft communication systems during air travel. A visual indicator, typically an airplane icon, confirms the mode is active in the menu bar.
The primary advantage of using this feature is compliance with airline regulations regarding electronic device usage during flights. Beyond air travel, it serves as a quick method for conserving battery power. By disabling wireless radios, the Mac consumes less energy. Moreover, it can improve security by preventing unintended connections to potentially unsecured networks. The availability of this feature has become a standard expectation on modern operating systems.
