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

Also I used the multybeast to install the voodooHDA drivers, can this be the problem???

Exactly. Go to the first page of this thread and read again.

In that case I would rather work with the Clover patch, "GBE1 -> ETH0".
If you only work with the SSDT, the existing device "GBE1" is hidden and a new device "ETH0" is inserted in the same place. This works great with many other devices. The problem here is that there are other connections to this device in the DSDT that will be interrupted:

    Scope (_GPE)
    {
        Method (_L6D, 0, Serialized)  // _Lxx: Level-Triggered GPE
        {
            \_SB.PC00.XHCI.GPEH ()
            \_SB.PC00.CAVS.GPEH ()
            \_SB.PC00.GBE1.GPEH ()
        }
    }

That does not happen with the Clover patch. Here all entries in the ACPI (including DSDT) are exchanged, all links thus remain active.

I never faced any issues with the GBE1->ETH0 replacement within the SSDT.. Cannot reproduce your concerns, master Nico..

If it's kernel panics in Premiere, it also happens with Vega, FYI.

This seems to be related to the iMac Pro SMBIOS/macOS/Adobe

nah I get KPs doing things like quicklook or even just letting the computer sit for a few hours. every time it's the exact same KP issue and the Nvidia drivers are always in the backtrace. I actually DON'T generally get KPs triggered by anything that taxes the GPU, weirdly enough. It's all completely anodyne things like playing a video in VLC or, like I said, Quick Look-ing something.

NVIDIA I could understand, but not Vega.

Do you have CUDA installed? Try removing and see if the issue goes away.

Delete the following:

/System/Library/Extensions/CUDA.kext
/Library/Frameworks/CUDA.framework
/Library/LaunchAgents/com.nvidia.CUDASoftwareUpdate.plist
/Library/PreferencePanes/CUDA/Preferences.prefPane
/System/Library/StartupItems/CUDA/

If you installed the tookits and samples, delete the following also:

/Developer/NVIDIA/CUDA-5.0
/usr/local/cuda

I'm thinking of setting up a 2nd SSD with Sierra (well maybe I'll try Mojave first)

These Premiere Pro crashes are getting ridiculous. I got 4 system freezes lockups.

Two types of system freezes, which can easily be replicated.

1) Scrub timeline with MP4 or ProRes or RED footage.
2) Export to any codec and move the mouse continuously.

If you have a YT video playing in Chrome and exporting/scrubbing in Premiere you will have a guaranteed system lock up.

That's absolutely true.. and that's why I am eagerly looking forward to the release of a LG 38 inch with the same properties as the LG 34 inch currently under discussion..

Just added a 38 inch LG (3840x1600) to my portable hack. Love it.

I was feeling lucky, I hadn't had one for awhile. I haven't been using Premiere to heavily lately (I export from a different machine). Then tonight, I had just finished using Premiere and was watching a YouTube video in Sarari and it locked up. The irony was that I had just thought, "Hmmm...things are going well, no lockups!"

I've been following the ultra-wide LG monitor discussion with interest. One question, since I'm unfamiliar with monitors attached to multiple ports. – Does the monitor appear as one single display, or as two distinct (e.g. left half/right half) displays in System Preferences?

That does not have to have any obvious effects. I just wanted to emphasize that the cited code then has no function. And the developers of the ACPI certainly had a reason for that.

I you refer to the LG38U99-W, it of course appears as one single display in System Preferences as it is one single display.
