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

[izo1]

Ok I was able to install and boot into the desktop. Everything is extremely laggy though (using DisplayPort now instead of hdmi). I have whatever green and lilu for the rx560

I figure this might have something to do with apfs?

I format to apfs using another computer by nuking all partitions first with gpt destroy.

Then when formatted to apfs I mount the EFI Partition and put all the kgp files in there.

I caught it this time. And fyi seems to have happened 2x today.

I just noticed a line here...

PCI Card: pci144d,a804, NVM Express Controller, AirPort@225,0,0

I don't have anything external plugged in my setup... Is this an indication of some onboard wifi that is supported somewhat for Mac? Could this be using a system similar to AirPort Extreme? I'm just curious about that line and why it clearly says AirPort

also further analyzing some more of what it listed made me realize I had working audio the whole time though Nvidia drivers I guess. Just switched my output device to my monitor where I plugged in my speaker/headphones... I'm happy to have a full working system with video, internet and audio. I can't ask for more ... maybe I can but I'm so pleased with my build thus far.

Thanks to all you guys... and best of all... I keep learning and learning here and there picking up from this thread.

 

[send2moran]

still no 10.3.3 update on my app sote
starting to be scared that something is wrong with my config ...

 

[izo1]

I just can’t get this thing to work. This is sad. I spent a lot of money to build a new rig but it’s becoming a nightmare.

Already spent more than 20 hours and I can’t get the iMac pro version of High Sierra installed

Should I just do a regular vanilla macOS install instead?

 

[izo1]

Don't give up, some of us spent spent way more time than that This is not the easiest build, but with the proper settings it works very well.

Thanks for that.

I’ve tried about 15 times to install it.

It’s a no go.

Do you have any ideas? I’m using the gigabyte board that’s in the original post.

 

[izo1]

what is your status now? you installed but it's laggy? did you just copy the efi? did you customised for your build? post your efi and an ioreg dump if you can.

I formatted again and I can't get past the 11 minutes (sometimes it goes to "Less than one minute") and the bar gets stuck and does nothing.

I just tried HFS+ on the Samsung SM951 (AHCI) and it's still a no go. I pulled this m.2 SSD from my previous hackintosh, but I know NVME is now officially supported. Maybe this is the reason although even the booted USB stick is "laggy".

I'm going to try creating a new USB stick with the script from this thread and maybe try a regular 250GB SSD I have laying around.

I used the KGP EFI and added WhateverGreen and Lilu and serial number for the iMac Pro 1,1 that's all I changed.

 

[AnaktuvGod]

My system also thinks the nvme drive is plugged into an airport port, don't worry about that. osx seems to think the slot you use is for airport wifi cards, but your system, it is not. You could get around this with the proper ssdt edits if you want.

But there is no hidden wifi device in your build, that is for sure.

I don't know about this one @interferenc

according to this info here...this is the real deal.

Notice the link speed... Well according to the manual and I believe the Asus prime has it as well, this would coincide with the description of the the (WiGig) 802.11ad wireless adapters @60Ghz on our boards. Was doing some surfing on google and found some info on converting GT/s to hertz and it seems to make sense. I referred to this link https://www.itproportal.com/2008/09/15/gigatransfer-gt-and-megatransfer-mt/

I really do believe this is the WiGig card we have on our boards and based on that link... 8.0 GT/s goes along with the (up to 4.6Gbps per the manual on WiGig) I think its an airport card we haven't put to life yet. All signs point to it.



Ok after further looking in the system seems all of them transfer at 8.0GT/s... how ever both my ssds show up in the nvmexpress tab on the left... but clearly theres one listed under PCI as well and AirPort on top of that. With the high-end 802.11AD having Mac show it as an AirPort is something I just believe it's possible with the right tweaking. Says airport for a reason....I aint do it.. you didn't do it lol. IJS. Just need to confirm the location of Slot 225,0,0 on these boards.

 

[AnaktuvGod]

Listen, the SLOT is marked as AirPort. The device id is pci144d,a804 which is a Samsung 960 EVO. The link speed is speed between the processor and the device, pcie 3.0 x4 is 8 GT/s.

Yes you are correct lol.. Sorry bout that. Just got geeked seeing AirPort. Back in my little corner I go

Hi guys!

I need a little help, yesterday I tried to fresh install 10.3.3 with iMacPro SMBIOS. I just made the installer disk, everything went fine, every step was OK. I disconnected every single SSD, HDD, only attached the USB installer and the final SSD which had Windows 10 previously. The USB installer disk simply doesn't show up in the Clover screen! I tried to reboot many times, but nothing. Anyway I grabbed my previous USB installer disk (10.3.0) and I just installed the system with iMac 17,1 SMBIOS. Then I updated to 10.3.3 via App Store, went fine. Then I tried to change the whole EFI folder for @kgp 's EFI, but oviously I changed the voodootscsync.kext (8 core, 16 thread, I put 15) and generated a new serial and SMUUID. Reboot and nothing. EFI is working, I can choose disk but after that, black screen, then the system shut down. I thought it has to be AptioMemoryFIX.efi problem, (I couldn't crate my own with the script, I attach the terminal message)

so I tried to change for OsxAptioFix3Drv-64.efi. Doesn't work. Then I tried so many various of these efi files but I couldn't find any good. Even with my current system's OsxAptioFixDrv-64.efi + Test2.efi doesn't work on this system. So I don't really have idea now what to do, I can't boot this system with iMacPro SMBIOS, only with iMac 17,1 SMBIOS.

If someone could check my EFI folder, that would be nicely appreciate! I attach my current, working system's EFI too!
