EFI from version 1.4.0 does not boot on X280 #156

Hi, I downloaded your EFI, changed MLB, ROM, SystemProductName, SystemSerialNumber and SystemUUID and the system reboots after about 2s after the loading bar is visible

Everything worked on commit #89b992d (usb mapping) and below

(I have MacOS 14.3.1 and I don't use Heliport)

I installed 1.2.2 efi for ventura, then updated all kexts and opencore and updated to sequoia from app store (remember to turn off securebootmodel and enable verbose) and everything works perfectly fine 😎 the only downside is that it takes more time, but nothing is difficult if you want
