Reply: macbook air A1369 EMC 2392 efi lock after format

This does appear to be an EFI lock of some sort. The EFI Destroyer Light will remove this, or you can try the method using a raspberry pi outlined in the guides.

Hello! A relative bought a macbook air A1369 EMC 2392 and after formatting it (following a youtube video) it displays this sign. it seems to ba a software key. How could i unlock it? I read about taking off the ram in the pro model but this one has no extractable ram l. Are there any solutions to my problem?
Best regards
