bridgeOS is an operating system created and developed by Apple Inc. for use exclusively with its hardware. bridgeOS runs on the T series Apple silicon processors[1] and operates the OLED touchscreen strip called the "Touch Bar"[2] as well as multiple other functions, including managing the encrypted data in their Secure Enclave and acting as a gatekeeper and video codec to the device's cameras. bridgeOS is a heavily modified version of Apple's watchOS. It was introduced in October 2016,[3] removing it with the 2021 MacBook Pro.[4] The Touch Bar was criticized because of it replacing the function keys.
