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

[YPSuperman]

Please post your EFI zip.

Are you using AptioMemoryFix-64.efi and not any other Aptio fix? (The zip in 1st post has all the necessary kexts and .efi files to get you started)
Also CsrActiveConfig should be set to 0x67 on config.plist

Hey,
Thx a lot for your reply!!
I am using the aptioMemoryFix-64.efi and also the AptioInputFix-64.efi.
CsrActiveConfig is set to 0x67 on config.plist..

I attached my EFI folder so you can hopefully fing my mistake(s)!

best,
Phil

Thanks a lot for this thread !

But, why you don't use this CPU ? https://www.amazon.com/dp/B07BRVNM4M/?tag=tonymacx86com-20

It's the native Imac Pro CPU right?

Best,

Because …
• the processor is more expensive
• you have to use another board (C422 Chipset)

Hi

Thx for your awesome guide! Maybe you could help me with my installation issues?
I followed your guid as good as possible but somehow the installation crashes with:
"Couldn´t allocate runtime area"

I Uploaded a picture of the issue and my EFI Folder. I really hope there is a solution to be found!

Thx for everything and best greetings,
Phil

Asus Rog Strix X299

Phil, everything in your EFI-Folder seems alright.. BTW.. THE CPU core ACPI replacements you enabled are for the i9-7940X?

Thus, I really don't know what causes the memory allocation errors with your mainboard..

Try to enable "above 4G decoding" in your BIOS... If this does not help try to reflash the BIOS..

Cheers and good luck,

KGP

There is one more thing :
• The 7980XE is much faster since you can overclock it, what is not possible with the Xeon. ;-)

Looks good to me, but let's try these...

Can you delete all the files in drivers64UEFI and put these from the drivers64UEFI.zip (attached) in it? They are the latest.

Can you replace the kext files with the ones attached in newkextfolder.zip

Can you use the attached config.plist?

OR just download this attached EFI_modified_YPSuperman.zip and completely replace yours [delete current and copy this over] (keep a backup of yours somewhere). Make sure you only use the EFI folder inside

Report back if it works.

Hi,

In bios select your disk about install the operation system and EFI partition.

Guide Update completed

1.) Black Screen on wake issue not caused be the current Vega system implementation but by some experimental XHC1 setup exclusively installed on my own X299 System. Neither the guide nor the formerly distributed Vega System SSDT with default XHCI implementation have been affected by this problem.

Sleep/Wake functionality fully recovered on my Vega Skylake-X/X299 System.

2.) Anyway note the following updates in SSDT-X299-iMacPro-Vega.aml and SSDT-X299-iMacPro-Nvidia.aml, newly attached to the originating post of this thread (guide):

a.) DTPG method outsourced from both files to SSDT-DTPG.aml and now implemented in form of external DTPG method calls within the definition blocks of both system SSDTs, as formerly already implemented in case of the SSDT-9-TB-minimal-hotplug-injector.aml. Note that it is now absolutely mandatory to add SSDT-DTPG.aml to /EFI/Clover/ACPI/patched/ also in case of the System-SSDTs!

b.) Adding THSS Intel X299 Series Thermal Subsystem Controller PCI device implementation kindly provided by @apfelnico to system SSDTs:

    Scope (\_SB.PCI0)
    {
        Device (THSS)
        {
            Name (_ADR, 0x00140002)  // _ADR: Address
            Name (THSS, One)
            Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
            {
                Store (Package (0x0C)
                    {
                        "AAPL,slot-name",
                        Buffer (0x09)
                        {
                            "Built In"
                        },

                        "built-in",
                        Buffer (One)
                        {
                             0x00                                 
                        },

                        "name",
                        Buffer (0x24)
                        {
                            "Intel X299 Series Thermal Subsystem"
                        },

                        "model",
                        Buffer (0x24)
                        {
                            "Intel X299 Series Thermal Subsystem"
                        },

                        "device_type",
                        Buffer (0x13)
                        {
                            "Thermal-Controller"
                        },

                        "compatible",
                        Buffer (0x0D)
                        {
                            "pci8086,a2a1"
                        }
                    }, Local0)
                DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                Return (Local0)
            }
        }
    }

which also results in a new Section E.9.2.9 and a shift in the numeration of all following subsections .

3.) New EFI-Folder implementation EFI-X299-10.13.6-Release-iMacPro1,1-010918.zip

EFI-Folder related changes:

Implementation of Clover_v2.4k_r4664

4.) Implementation of v.1503 ASUS Prime X299 Deluxe iMacPro Splash Screen BIOS firmware distribution
X299D.CAP.zip

5.) SafeSleepUSB.app or Jettison.app might help in circumventing the USB ejection error during sleep/wake, see Section E.4).

The respective 10.14 PB8 guide update for iMacPro Skylake-X/X299 under Mojave also has been successfully accomplished this evening by considering all of the above mentioned points in addition.

Enjoy and have fun
