i bought Macbook air 13" 2017 two months ago. it doesn’t show serial number instead it shows ˇˇˇˇˇˇˇˇˇˇˇˇ this as serial number.
Hi That’s really strange it could be a dodgy OS install on it,if you want you can reinstall it any it might fix your issue If it’s the serial number you are after if you look at the bottom of the device ,it will be there in small print Hopefully this helps Thanks:-)
