Skylake-X/X299 and macOS Sierra 10.12 - [Successful Build/Extended Guide]

[PNZ]

1.) It worked with X99 under 10.12.6 and 10.13.... I see no reason why it should not work with X299
2.) I would definitely go for the ASUS! The best choice ever with respect to XCPM!
3.) o.k., perfect!
4.) I just bough the Corsair 760 T arctic white, because it accommodates a lot of SSDs and HDDs. You might fancier cases if you need less disk space though and mainly go for NVMe and SSD

I hope this answers your questions

Cheers,

KGP

Thank you very much for your support!
So I'll keep an eye on your future liquid cooling system
About the motherboard, I have the chance of an MSI x299 XPower Gaming AC for a such a good price for saying no...
Probably I'll take one for sharing the experience with the community. In the worst case, I know that your Asus works smoothly.
Or probably I'll surrender to an equivalent of the MSI quoted, like some Asus ROG Rampage

I'll keep you updated.

Thanks

Up and successfully running Skylake-X/X299 on macOS 10.12.6 Sierra!

Hello MasterKGP
1st: BIG HUGE THANK You for sharing your experience with X299
2nd: Sorry, some first posts were deleted cause my mistake - We should read forum rules... not 'only' fast click yes, accept etc ...
3rd point: I have 7900x (today stock, without OC) with Gigabyte Aorus Ultra Gaming
I configured my bios with your guide, then copy your EFI + nv_disable=1 (I have GTX 1070)
on my prepared 2 USB drives
It's much better than before (after my 'almost' 60h of tests for nothing)
but still some errors and still I can't Install Sierra...
so...

1st screen = boot and screen stopped for 10 sec - we can say 'everything is ok'
then 2nd screeen = 3s.. and PC restart

PS: 1x 960evo connected and 1x Sata Xyz SSD...
Scarlet 2i4 discoonnected
and nothing else...

and 2nd screen

Thank you for help if you have some ideas
Have a nice day!

I used the flag 'cpus=1' to solve this problem.But only one core enabled. everything is ok except the cpu problem.

Did you enable KernelPM? EFI installed on your boot drive?

 

[TwixQ]

Hello!
I'm also having alot of issues, solving one of them leads to another, I have been searching and trying (almost) everything.

 

[TwixQ]

With Efi from first post, kernelpm true, slide=0 and cpus=1.

Wait until the final release of my guide... It is a question of on to three more days... I am working hard on it... I will upload a new EFI-folder with the new release ... then hopefully problems will minimise

Hi MasterKGP
So Yes it was enabled and EFI Installed.
I tried with nv_disable (thinking about my gpu)
but most important was : boot with cpus=1 and without ..
and I tried with and without Intel Speed Shift Technology (Enabled or Disabled)
and I have the same problem like TwixQ but i have a Kernel Version 16.7.0 and TwixQ have 16.0.0

PS: Should we use the same CPUID for me and TwixQ?
He have - 7820x and I have 7900X

Have a nice day guys!
And I hope together we will find our solution soon - for all of us

CPUID is the same for all Skylake-X...

Cpus=1 is no solution

Wich mobo do you have?
