so i just bought a secondhand macbook air early 2015 and in about this mac my serial number says ˇˇˇˇˇˇˇˇˇˇˇˇ; how can i fix this ??? please help there is no apple store in my country.

Nima, Sometimes the Serial Number can disappear upon certain replacements to a MacBook, like a logic board replacement. However, I’m mostly concerned about the hardware configuration and I want to help you confirm that your hardware accurately being displayed. Go into Terminal and run this command: ioreg -l | awk ‘/IOPlatformSerialNumber/ { print $4; }’ See if it prints the serial number. Additionally, you can download Coconut Battery which displays the Serial Number. Go here to download it. From another forum: “If that doesn’t return anything, then you’ll likely need to re-serialize your board, which would require Apple’s Blank Board serializer, which is normally only available to Apple and authorized repair centers. You may want to try calling around to a few around you just to see if any are willing to do that for you.” Let me know if this helps, -Alex

this is what it showed, i guess there is nothing i can do considering that there is no apple store or authorized repair center in my country. thank you for your help
