But there were problems. worth the mac image. does not show the year of issue and serial number. how can you solve the problem? Tell me please

You’ll need to visit an Apple Store for them to reset the systems serial number.

Although I am not sure about how to solve it, I believe you can get the serial number that should be printed on the bottom. as apple says: “You can find the serial number and other identifiers for your MacBook Pro in macOS, on the computer’s surface, and on its packaging.” https://support.apple.com/en-us/HT201300
