If for some reason it doesn’t show, you can alternatively find your serial number by doing the following:

All MacBooks, or Mac computers in general, have the computer’s serial number imprinted on the back. However, it might not always be convenient to close your computer, or turn it around or upside down, or it might not be visible anymore after wear and tear.

system_profiler SPHardwareDataType | grep Serial
This will output the exact same serial number you can find under About This Mac and System Report > Hardware as you learned in the previous sections.
