How to build your own iMac Pro [Successful Build/Extended Guide]

[RuleBreaker01]

You can create any NVMe soft raid with disk utility and it will double the transfar rate of the raid if you use two NVMes..

Don’t understand where are the problems you see. Guess your way of thinking is by far to complex and complicated ...

I have no use for a fast disk that I can't boot.
Create a RAID (or encrypted disk) with Disk Utility, but AFAIK, you can't boot a Core Storage based disk (not the way a real mac boot loader can..

So that leaves two possibility:
1- Find Intel RAID mac drivers
2- Implement a boot loader supporting Core Storage.

The later would be better, I could encrypt my disk once again...

Well, now that I'm testing I found that sleep doesn't work.
Basically as I click on sleep the machine dims the screen and after a little while goes into sleep
but then it awakens immediately, after a couple of seconds, on its own.
How can I fix it?
Thanks a lot.

Hi all, new hackintosher here!

So I followed this guide and I can successfully boot from the USB installer. But then I am faced with extreme lag, to the point where it is completely unusable and freezes completely. It feels like I am missing something obvious. Any help is greatly appreciated.

Thanks,
Markus

Good luck,

Thanks a lot for the tutorial. It seems that everything works fine except the GPU temperature. It seems that only two GPU fans are running even the temperature is running high. My initial thought is that the GPU sensors are not properly set up. I'm using the FakeSMC included in your EFI-X299-10.13.3-Release-iMacPro1,1-200218.zip. I only see the SSD temperature in HWSensor. So I tried download RehabMan-FakeSMC-2017-1017.zip and put FakeSMC_ACPISensors.kext, FakeSMC_CPUSensors.kext, FakeSMC_GPUSensors.kext, and FakeSMC_LPCSensors.kext into EFI/CLOVER/kexts/Other/. But it caused a panic.

May I have your suggestions? Did I miss something regarding the GPU? Thanks a lot!

I installed 10.13.3 and graphic driver is 387.10.10.10.25.157.

My parts include:
Motherboard: ASUS rog strix x299-xe gaming
RAM: G.SKILL TridentZ RGB Series 64GB (4 x 16GB)
CPU: Intel Core i9-7900X
GPU: ASUS ROG GeForce GTX 1080 Ti O11G
Wifi & BT: Apple Broadcom BCM94360CD
CPU water cooling: Corsair Hydro Series H115i

Is there a way to enable F1/F2 on real Mac keyboard and real Mac display for brightness control without running Native Display Brightness Control app?

The real iMac Pro have some insane SSD speed (3.5GB/s read and write), iFixit tear down showed that for the 1TB option, they were using two 512GB SSD in RAID0.

If we could duplicate that setup that would be awesome

iMac Pro uses a new T2 chip which has a NVME controller and other things like image processor. I wouldn't recommend RAID0 even on SSD, there's twice the chance of failures. Most likely the T2 chip has some type of hardware error correction. You're not really going to feel the difference between 2.5GB/sec and 3.5GB/sec unless you're doing some major file transfers.

You are better off just getting a 960 Pro NVME drive instead and then just putting a cheap 2TB+ HDD in for hourly Time Machine backups.

I use an older 512GB AHCI 950 Samsung PCIe SSD (not even NVME) and it works perfectly fine. It's not as fast as a 960 Pro but it works well and I can open large files very quickly in Photoshop, etc. Even big red raw or uncompressed files have no problem playing back. I use a Hitachi Enterprise drive I got cheap off eBay from server pulls as a hourly Time Machine backup.

I'm basically narrowing down the sleep problem.
I've removed SATA controllers and other things and it turns out the issue is the
ABWB 802,11 AC WI-FI + Bluetooth 4.0 PCI-Express (PCI-E) BCM94360CD Combo PCIe Adapter
if the adapter is connected to one of the external ports (USB2.0, USB3.1) then as soon as the PC sleeps it wakes up.
BUT
if the adapter is connected to another of the external ports (USB2.0) or the internal USB2.0 header then it sleeps fine
BUT it doesn't wake up through Bluetooth anymore. I need to plug in a mouse or press the power button to wake it from sleep (on my AMD I can wake it from a Bluetooth device too, but maybe it's normal to have to wake it from sleep using the power button).

Anyone one have issue with iMovie freezing ? I am using an RX560 at the moment (saving rx vega 64 for another machine) and I am having stabiltiy issue with the rx560. Computer completely freezes and console log doesn't show any kernel panic.

When you find out, let me know.
I haven't been able to get that part going, a press of F1 just turn off the screen.
Auto brightness no longer work either...
