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

[kgp]

Anyone having a problem with web driver for 17F77 ? My displays work correctly on boot but will not come back on after display sleep. Displays turn on and off repeatedly with no picture. I have had this issue before, but with the latest drivers it seems worse. Should I patch an old driver in the meantime? Is there a better fix to this issue? Waking from display sleep always takes longer than it should, even with older drivers.

Use NvidiaGraphicsFixup and Lilu!

see post #8272... sorry to destroy your dream and hope..

Haha, No problem, just didn't want to perform a patch on a bios unless necessary, thanks!!

Install MacOS onto the drive as usual, then boot up through your USB clover and select the NVME drive to boot off of to continue the installation. You can copy your EFI folder over later. You absolutely do not need to format and prepare the drive using another system before installing.

You dont have to. So long that you have the USB installation disk with the right EFI partition, you can boot on it and format the disk later via disk utility.

You can completely wipe the drive from terminal when you boot off the USB key installer.
(Google for the terminal commands)

Or if you have windows installed, boot into windows and from the command line as admin and run the following (check with disk management to see which drive it is):

>diskpart
>list disk
>select disk X (ie 0 if it is that)
>clean

The clean command will completely wipe all partitions and your drive will be as if it came from the factory.

Be careful running these commands because you can wipe another internal drive without knowing.

I suggest you disconnect all unnecessary drives before doing these and double check in disk management which drive exactly you’re wiping.

After these commands you can install fresh from your boot usb.

Thanks all for the clarification!

@izo1 got any recommendations for a program to stress test the graphic card?

Got the response from AMD have to ship it to Holland, they don't appear to offer a fast replacement service in Europe.

FurMark and Valley are good, both available for macOS.

FurMark is super heavy and pushes the GPU a lot.

I wasn't sure you were in Europe since you ordered from NewEgg.

Thanks all for the clarification!

No problem, another good way is to actually "zap" (aka Secure Erase) the SSD. If it's a Samsung drive, make a bootable USB key with Samsung software in Windows (with CSM enabled) and boot into it and wipe the SSD that way.

If it's not Samsung, download Partition Magic and make a bootable usb key and wipe it that way. SSD's work differently than Hard Drives in terms of wiping.

Has anyone had this problem with USB 3.0 external drives?
I think I Mentioned this a while ago but didn't find a proper solution.

Basically if I leave a USB3.0 drive connected for a day (it doesn't go to sleep and sleep is disabled on drives and overall system) the drive will show the contents but I can't write anything to it (but can read).

Trying to eject is a pain because it asks for every app to close and sometimes requires a restart.

Any help appreciated.

Hi guys,

thank you so much for this awesome guide! I really appreciate it. But I guess me is just as noob as every noob: Clover does not give me an USB Install Entry.

Is there anything specific different from this guide for my CPU (i9-7940X)? I am just not able to boot from Installer USB. I tried different ports and I started three times over.

This is what I did:

1. Installed windows on an SSD
2. Set BIOS according to guide
3. Followed Section D) using USB stick and HDD (Later I am planing on copying to NVMe) using EFI-X299-10.13.5-Release-iMacPro1,1-010618 and Mac OSX 10.13.5
4. No Clover at all (my mistake: copied the contents of @kgp's EFI folder instead of EFI-folder to EFI-Partition)
5. Got the Clover boot screen with only option to boot into Windows
6. Since then I repeated these steps: Download High Sierra 10.13.5, made USB stick with Terminal, copying EFI-folder to HD for installing Mac OS X
7. Made USB with UniBeast, replacing UniBeast EFI folder with @kgp's; following this post by @XRaegun. No luck.

Clover just won't show the USB installer icon. I double checked everything. As for every noob, I am missing something - something specific to my CPU?

Clover gives me the option to boot into Windows. Booting into Windows this way does not work - if I need to, I just switch on Fast Boot in BIOS - so I am not worried about that right now. Later I want dual boot. Researching this thread, a few people have had the same problem. All of the solutions I read about won't work.

What can I do?

Thank you so much for reading!

What about boot.efi? BTW.. Don't use UniBeast for X299 ..

Hi, thx for asking. Always had boot.efi in .IABootFiles. I just used UniBeast because @XRaegun mentioned it. I read that you are advising against it. Windows was installed with UEFI mode. I am very sure, that I made no mistakes in BIOS setting and following section D). Are file and folder permissions relevant on USB installer sticks?

I don't advise against UniBeast.. I just do not recommend to use it for X299. An if you use UniBeast you are OOT here in this thread..

Oh sorry, I was not clear enough in my post. I understand that you are not recommending it.

I will redo the installation process, pretty sure I missed something. Will start frome scratch. Good night, sir and thanks for all your efford - really impressive!
