I think gyroscope/accelerometer is deprecated in MacBook started from ~2012. It's called Sudden Motion Sensor or SMS. There is a command called "sudo pmset -g" and if SMS, if is exist, will show "sms: 1" or "sms: 0". Reference: https://www.lifewire.com/manage-mac-sudden-motion-sensor-sms... My MacBook Retina 2014 do not have any SMS record.
