Macbook Pro does not recognise Apple ID
Hi, as has been posted before (with no helpful advice given).
My Macbook Pro won't recognise my Apple ID password (it is definitely correct as I can use it to login on Apple website as well as icloud.com.
Please help as I can't update my macbook and everytime I start it up icloud asks for the password and won't recognise it when its typed in.
Thanks
MacBook Pro with Retina display
