bridgeOS is an embedded operating system created and developed by Apple Inc. for use exclusively with its hardware. bridgeOS runs on the T series Apple silicon processors^[1]^[2]^[3]^[4] and operates devices such as the OLED touchscreen strip called the "Touch Bar",^[5] TouchID fingerprint sensor, SSD encryption, and cooling fans.^[6]

At boot time, the bootloader executes the bridgeOS kernel, then the bridgeOS kernel passes off to the UEFI firmware.^[7]

bridgeOS is based on Apple's watchOS.^[8]
