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

[ffltt]

Hello my friend,

that's somewhat surprising. Did you already install 10.13.4 before? If not, download the 10.13.4 installer following section D.) of my guide and try to subsequently update to 10.13.4 SU. In this way, you could also try to directly download the Base.dmg of / or the entire 10.13.4 SU update installer.

I install 10.13.3 ,and I updated 10.13.4 from AppStore,but I can not receive the latest security update file through the apple store, I'll see your guide right away, thank you so much my friend

I have a build that has totally disintegrated. At first, I was able to boot into the Installer from the USB (Unibeast created) but on reboot the system would hang after half the progress bar. I went into your tutorial and tried to reinstall using your EFI-X299-10.13.4-SU-Release-iMacPro1,1-260418.zip but I ended up with hangs there as well. I've gone through the BIOS and made sure it matches your specs exactly. I've flashed the BIOS with your updated "unlocked" version. Nice splash screen btw. There are no other cards or drives plugged in.

After subsequent restarts, I cannot, regardless of configuration or attempts at modifying my config.plist or drivers, get the boot to go past the message "couldn't allocate runtime area". It seems to have devolved to a point that the boot barely starts before shutting down. I had a successful Sierra install on another hackintosh so I used the USB Installer from that system and the Sierra installer also won't go past "Error loading Kernel Cache (0x9)" and alternatively, "couldn't allocate runtime area".

Specs are:

I9 7920X
Asus Prime X299 Deluxe
128GB Corsair Dominator (3200mhz)
GeForce GTX Titan Black
2x Samsung 960 EVO 1TB in M.2 slots

Any help in getting this system up would be immensely appreciated.

@ spencer.meffert: Try booting the system, either with an Ubuntu USB 3.0 thumb drive, or else Windows 10 from a "Windows to Go" external USB 3.0 thumb drive.
That should show whether it's a hardware vs. software problem.
The "Windows to Go" thumb drive needs to be at least 32 Gb in size.
Alternatively: a USB 3.0 -> SATA adapter cable would allow using a standard 2.5" SSD, and would be much faster than a USB 3.0 thumb drive.
Note: there are no USB 3.0 -> NVMe M.2 SSD adapters that would work with the Samsung 960 EVO, at present (AFAIK).
Also try: clearing the CMOS.
Samsung has an SSD firmware update utility which AFAIK, only runs on Windows. So that a bootable external USB 3.0 Windows device would be something useful to have, in case of occasional need.

1.) Never use Unibeast with Skylake-X/X299!
2.) When using my EFI-Folder, did you add TSCAdjustReset.kext?
3.) If your system still does not boot, revise once more your BIOS settings
4.) Forget about Sierra
5.) Learn to provide a detailed bug report
6.) Add your Skylake-X/X299 system specs to either your profile or signature.

Thanks in advance and good luck,

KGP

Hey guys, just cloned the OS drive from 512GB M.2 AHCI (non nVME) to a 1TB Samsung NVME. Using the NVME External .aml. All works well.

However, on Clover now it seems it's seen as an external drive so it's all wonky. I've set the proper UUID for the boot drives.

Any help appreciated.

Just try another Clover Theme..

Well the problem is clover doesn’t see the nvme with a proper uuid in the config file. Weird.

@kgp and other interested users, in the delid process, I also used a different ihs, the original ihs is nickel and the contact with the liquid Grizzly is not a good idea because it deteriorates the ihs. The other ihs is copper and apart from improving the conductivity, it is not degraded by contact with this type of liquid, greetings.

Well.. I guess that's partly what made your day..

Anyway, no way to successfully run Geekbench on my i9-7980Xe sample with 1.25V core voltage and @4.9Ghz.. I increased the core voltage even up to 1.38V, no way to pass the Geekbench benchmark. My system just would reboot during the benchmark.

With my sample, I just successfully pass Geekbench with 4.8Ghz, even with SVID enabled and Core Voltage on Auto..

Although at this frequency and with these BIOS settings, CPU temps would exceed any reasonable limit, when performing a Cinebench CPU benchmark. For the latter benchmark, 4.7 GHz are the optimum to be achieved. A copper IHS would certainly help in this case.
