I am not sure if anyone has any suggestions or insight into this problem, but recently a random MBP has been showing up under my devices when I log into find my iPhone. I always securely wipe and restore all systems before selling or trading in. Is it possible that this is a glitch on apple's end? I cannot believe the idea that someone else is logged into my iCloud account as I have noticed no irregularities or problems. I have removed the device from my list but it reappears when the computer comes back online. Thought or suggestions would be appreciated.
