hey, I love your work! I was wondering that if your Lenovo T440s EFI will work on Lenovo x240? it has almost the same specs.

[MultimediaLucario]

If your Lenovo ThinkPad X240 has an i5-4300U CPU and not a i5-4200U or i3 then I think it would work perfectly.

[sxqib]

thanks for your reply! yes it has a i5-4300U CPU. I tried on monterey and it worked flawlessly!

[MultimediaLucario]

The EFI works better on Intel GPUs but I will get right to patching an EFI that is optimized for i5-4210U.

Try this EFI with the MacBookAir6,2 SMBIOS: https://www.mediafire.com/file/k0cx1igi0fcviub/EFI_%2528ThinkPads_with_i5-4210U%2529.7z/file

Let me know if it works. 😎

Thanks @sxqib and @MultimediaLucario , I try to add '-wegnoegpu‘ in boot-arg and enable the CSM in BIOS, the problem never happen again.
