bridgeOS is a mobile 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.
