Hi,

I'm using 2020 intel MacBook Pro for the past one year. I entered my MacBook serial key in Apple website, initially its showed the service status of my Mac. But now it shows invalid serial key. I don't know what happen. Please help me out!

NOTE: I reinstall MacOs BigSur according to apple recommendational shortcut cmd+R.
