[pastrychef]

Is this a Terminal input?

Yes.

Thanks for the post, it worked on both 10.13.1 and 10.13.2.

I tried 10.13.2 and found the 0x55 at 0x22474, replace with 0xC3 as the post #1 and it worked.

Applied the edited version on two custom macs and both worked. One of them was Nuc6i7kyk, which used to show the log for quite a few seconds.

Actually, I wrote this string from the post #1 when looking for 0x55:
00 48 83 C4 48 5E 5D C3 55 48 89 E5 4D 89 C1 48
And use it again in 10.13.2 to locate the 0x55. The string appears only once, so it seems safe to try. Of cause, use at your own risk.

Yes, copy and then patch the apfs.efi file to your EFI partition with the code below:

cp /usr/standalone/i386/apfs.efi /Volumes/EFI/EFI/CLOVER/drivers64UEFI

perl -i -pe 's|\x00\x74\x07\xb8\xff\xff|\x00\x90\x90\xb8\xff\xff|sg' /Volumes/EFI/EFI/CLOVER/drivers64UEFI/apfs.efi

You could use it in a script as it seems it should work with future apfs versions.

Thank you this works.

Does this relate to weekly firmware check warning?
I still got that warning sometime on 10.13.3

I created a disabler kext... you'll probably find it if you search for it.
