Quick hardware test, hold D on boot
Serial number check at apple https://checkcoverage.apple.com, see for confirmed purchase date, expired warranties (or not)
No iCloud should be linked (Settings -> iCloud), ‘find my mac’ should be off
Check if the Firmware password is set, Cmd-R during boot and go to Security settings, should be off
Turn Firewault off (Settings -> Security & privacy)
Model hw (A1502 for example) and SN should match the HW specs (check on https://everymac.com/ultimate-mac-lookup/)
Battery cycles check
Overall state, screen hinges
Keyboard, all keys
Screen test, search for pixels (https://www.eizo.be/all-monitors/accessories/software/monitor-test/)
