I found the reason for upgrading the 10.13 kernel panic.
Workaround: MSR 0xE2 _xcpm_idle instant reboot (c) Pike R. Alpha Patch MatchOS 10.12.x Add a 10.13.x
（only smbios13,3）

Almost all patches can be use on 10.13.
The major problem is audio no more working after sleeping.
I don't know why, that's wired.
The same kexts/fix in 10.12 work fine.
And I found that if you don't turn on retina, the everything of HDMI works like a charm.
But if you once use retina, it broken everything.

hda verb may be broken.
I sent command via hda-verb directly worked in 10.12, but in 10.13, no reaction.

Hi soto2080,

Did U update your bios to the latest version (E5CN61WW : 2017/09/13) ?
If YES, Is it working good with macOS? Does it let clover boot?

Oh and what about macOS high sierra? Do you have any plans to make an updated guide?

The latest BIOS works fine.
Guide for 10.13 is here.
But if you feel comfortable with 10.12, no needs to update to 10.13.

Thanks, I updated my BIOS.
And thanks for the new guide and files for high sierra too.
I have problem with HDMI. I need HDMI because I use an external display most of the time (specifically at work).
But the HDMI won’t work most of the time (as we discussed before), sometimes it works randomly and when it works, it’s unstable (glitch after sleep).
So I fresh installed macOS high sierra 10.13 and made changes to the AppleGraphicsPolicy and tested with both SMBIOS 13,1 and 13,3 but no luck
The internal display turns to black.
Any idea or solution on this problem? any other steps needed?
Thank u.
