So.... like always .. I finished a new (clean) 10.13.1 install
BTW: My name should be GregCleanInstall with so many clean tests etc
1-) FakeCPUID still needed,
AMD Vega cards still have the same bug with Chrome, build in graphic editor, electron apps etc
(we have to wait December)
2-) and
my iMessage stil doesn't work
If someone with Skylake X (without KGP which have magic powers)
tell me: -
Yes, My iMessage work, in my opinion it will be not true or he is a very big lucky
because last few days I created 2 HackMacs for my best friends and everything works fine with 18,3 -7700K etc
but after 30 reinstallation's, 10 guides, and weeks of tests, MY own "old" or new iMessage account never work.. (17,1 X299 build) so... hmm .. maybe something will change in December or I will meet some magic MacCopperfield
PS: Every comments like, "you missed something" without details were/and still are not helpful :]
BTW: I tried some other MacPro 6,1, 14,2 18,3 etc SMBIOS versions, add or change last 5 letters or MB numbers,
every time SN checked on 2 websites, always new generated smUUID, and rtvariables options checked...
so .... if you know some abracadabra trick
let me know
PS2: even when I called Apple in Canada, 2 weeks ago, and they registered my new "perfect Mac"
...
the problem still existed
3-) Graphic Problem 
I've stared one LuxMark test --> GPU fans 100% in 1 sec. -> BLACK screen --> PC restart
and 2hour of test to reboot system... because I couldn't boot my PC with any image
or it was BIG (even Clover) graphic BUG... - even with my backup SSD with old OS X version ETC.
Now I know: it was some of BIOS changes ...
some of NEW bios implementations (changes for sleep/wake)!
It's too late and I couldn't try more, but first few test was
- with and without ASUS Multi ...enhancement
and especially WITHOUT new Platform Misc Config ..changes
- PCI Express Native Power Management etc etc...
I'm not sure but maybe it was that...
Later.. I will try to find which of "today-Installation" BIOS changes causes that horrible bug...
4-) Other things like:
- Both LAN - works perfect (IntelMausi + SmallTree...kext)
- Integrated Audio - OK (AppleALC 1.2.0) ** old or new version always works perfect for me
- Ext. Audio USB - Scarlett 2i4 (works great oob) - OK
- VGA - Vega 64 (with old bios settings) - OK
I use lilu 1.2.0 and whatevergreen 1.1.2
Have a nice day!
