Oh yes, and you asked about running accelerated stuff - when the internal display is corrupted (in which case the external display is set to primary and is attached to the eGPU), the eGPU side works fine including acceleration.

As it happens I made a (demoscene) demo last weekend and I put a GPU selector in the UI - i.e. it'll list all available (metal capable at least) GPUs, and let you switch between them and see what performance is like immediately, so it's easy to check if there are any issues there. (If anyone is in need of a mostly useless but maybe entertaining app that lets you check GPU support:  https://demozoo.org/productions/188683/ )

Soon I will add my system & eGPU details or a build link to this my signature to give context to my posts

Would be interesting to see the result of this command:

ioreg -n GFX0@0 | sed -E '/{/,/\| }$/!d' | grep \"device-id\" | sed 's/.*\<\(.*\)\>.*/\1/' | sed -E 's/^(.{2})(.{2}).*$/\2\1/'

 

That's a lot of of regex 😉 Output of that: 6938

And yes, there are matches for 0x69381002.

What do you think the block is here? It's clearly workable somehow as it works fine under 10.13.3 with the old enabling script, just not with Apple's changes with 10.13.4+. Is the AMD/Nvidia framebuffer conflict new in 10.13.4?

Something new in 10.13.4.

Status update: I was able to bypass Clover's complex DefaultVolume logic. Now it's much simpler.

iMac users that have built-in AMD cards who are facing issues with NVIDIA eGPU: maybe disabling AMD GPU acceleration (I'm sure iMac Pro users don't want that so they should skip out) might help (cannot test myself):

sudo nvram boot-args="-amd_no_dgpu_accel"

Do try. If it doesn't work out, just reset NVRAM or do:

sudo nvram boot-args=""

In recovery or if you were able to boot.

Thanks @mac_editor. Just tried with the M370X, worked as intended, progress bar halted and the Apple logo stayed on the internal screen. Luckily, the USB stick "EFI Boot" came to rescue and produced Nvidia eGPU screen output. No dGPU acceleration, the internal display was still there. Oddly, moved windows into the darkness became half black as well 😀

I guess we need to disable the dGPU completely or the framebuffer part.

SIP nvram protection must be disabled, otherwise this command doesn't work.

Switching the mux to iGPU would resolve internal screen stuck on Apple logo (ForceIntegrated).

@goalque There is actually a very interesting agdp=<board-id> boot-arg too. So one can pass a different mac board ID to AppleGraphicsDevicePolicy. Wouldn't that be interesting. Have been posting on the macrumors forum (about failing dGPU) where I learnt about this one 😉

Switching the mux to iGPU would resolve internal screen stuck on Apple logo (ForceIntegrated).

The previous test was conducted with the ForceIntegrated=true flag.

Test 2: Unchecked "Automatic Graphics Switching" (dGPU always on), ForceIntegrated=false -> The same Apple logo and progress bar stuck at a halfway. The UI feels a bit snappier. Safari's top bar still goes black (gradient) sometimes if you move it too far to the left.

Interesting. I would have bet my money on the internal display working fine if the mux was set to iGPU. I can accomplish exactly this on my NVIDIA MBP (tho not using Clover). Not setting mux = same exact issue of Apple logo being stuck. Perhaps manually setting the mux (using the long NVRAM power prefs command) may help. Unsure.

Maybe it's about timing, nvram setting takes control before my EFI app tries to switch gmux state (too late). I will play a bit more, interesting.

@goalque You can make selected gmux state permanent with agc=-1 boot-arg if needed. Have detailed these commands in the troubleshooting guide's command line section. But may cause eGPU to not work.

@mac_editor The long nvram power prefs command worked, the iGPU is active via "EFI Boot" and the dGPU does not appear in "GPU History". SafeEjectGPU gpus says "<unavailable>" for the M370X. Actually now some apps may prefer the second available discrete card, which is the Nvidia eGPU - even if you don't have the eGPU display connected.

Woohoo can’t believe the preference thing worked. 😋

Tho disabling AMD GPU should not be needed if preference is set correctly and eGPU is detected removable. Try testing in that config too.

Thank you for this amazing solution!
However,
I have a MacbookPro 2017 without touchbar
HP Omen Accelerator 
and a non-brand nvidia gtx1060 3gb graphics card which came as a set when I bought my Omen Accelerator.
When I tried to install this on my mbp's harddrive,  it said that my card isn't supported.
But my card can be properly used in bootcamp and also works with the former purge-wrangler solution.

Soon I will add my system & eGPU details or a build link to this my signature to give context to my posts

Wow! Thanks @goalque for all of your efforts. Really amazing work! So, I gave it a shot last night. Here's the skinny:

I did a clean MacOS install. I plugged in the eGPU, and ran the installer. I went throught the setup, noting the warning that my machine could only use hybrid mode. I went with that, and I saw a notification that said it detected the 1080 GPU, the web driver downloaded, and the install reported success.

That's where my problem started. I restarted the machine, and when I got to the login screen I plugged in the eGPU. I have a Razer Core, so it powers itself on when a connection is made. I saw the light on the Core fire up, fade out, the keybaord backlight on the Mac whent to full brightness and the machine locked up.

I then restarted and tried to plug it in after I got to the dekstop. In that case it looks like the eGPU lights up, but the screens never kick on, and I don't see the 1080 in the nVIdia driver prefs screen. I do see something in the System Report under the PCI section that suggests it sees a card, but the driver doesn't seem to kick in.

Also, I tried to plug it in with the machine off and powering up. Doing that seems to prevent it from booting.

So, sadly, it didn't work on my setup. The thing is, I'm not entirely sure I'm doing things correctly. I might be missing some critical step. so if you guys have any tips on what I could try I would aprriciate it.

For reference, Previously I had things working with PurgeWrangler so I know the hardware at least kind of works together. 

Thanks!

@goalque, very nicely done. How did you change the GTX980 eGPU from discrete to removable so can then set an app preference to removable, eg: Clover patch?  Having this ability would also be handy to the Hackintosh community to reduce configuration steps to get app GPU acceleration.

Tho disabling AMD GPU should not be needed if preference is set correctly and eGPU is detected removable. Try testing in that config too.

Some apps and even some OpenGL games (FireWatch for example) are programmed in a way that they always prefer dGPU, even if you have eGPU monitor set as the primary. Disabling AMD dGPU is therefore recommended. OpenGL (such as Valley) requires a headless ghost adapter. If you try to run without, it definitely tries to utilize GTX 980 but prompts an error message:

However, this time the internal screen was set as the primary, and no display mirroring, and no need for Spectacle app. Still worked! Metal accelerated games should work without the headless adapter. I will test later.

@DannyVegas @mac_editor knows the best what is the correct config.plist hybrid setting for your problematic 750M model. I remember that you always have to hot plug during the boot process, not sure about ForceIntegrated. You might need the power prefs nvram command prior to next boot.

PurgeWrangler uses identical patches, only difference being that it modifies plists/binary files. The EFI boot does everything on the fly, no system file modifications at all.

@jack_dorsey only the 6GB version is on the supported card list, already said 3GB will be added later

With the original AppleGPUWrangler patch, that brings the "disconnect" icon. The optional new workaround hides the icon completely, and in that case, the eGPU is detected as "discrete", I suppose.

@goalque came across exactly the same issue with OpenGL app without external display attached and dGPU running too. I have a feeling there are a lot more preferences that can be set.

@DannyVegas plugging at the lock screen may not work for this mac. Please try plugging in as soon as boot begins. Also ensure you are using older NVIDIA web drivers (378.xx) for both OpenCL/GL + Metal acceleration.

@mac_editor thanks for the suggestions. I think I tried that, but I'll give it another go. 

I started from a clean slate, so the Nvidia drivers I am using are the ones installed as part of @goalque's installer.

It's showing:
387.10.10.10.35.106

So you are saying I should replace them with 378. I'm not able to try now, but doesn't that only work on 10.13.1? I'm on MacOS 10.13.5.

People forget to press Command-R, reinstall macOS and ensure that the system is 100% clean.

I am thinking about adding /Library/Extensions & /System/Libarary/Extensions validation, browsing through all files - if one modified kext found, or has incorrect permissions, the installer refuses to install anything.

@dannyvegas Web driver can be patched for use on different version of macOS (using webdriver.sh). You can alternatively try purge-wrangler 4 - have had 100% success if plugged in while booting (387.xx - for metal only, 378.xx - both metal/openCL). Though EFI should have worked flawlessly too, since I had 100% success with that too 😉

Confirmed. It was first difficult to reproduce @PaperHeart's finding where M370X was accelerating the internal screen without any UI lag.  He had to have some app open that activated the dGPU at the time of hot plugging (Visual Studio Code in my case). Now everything is smooth, no any sluggishness. We were in belief that AMD dGPU and Nvidia eGPU were conflicting each other - in the default state yes, but not when hot-plugged-logged-out-logged-in and AMD dGPU was pre-activated by some app.

Internal screen acceleration worked similarly as with the Iris Pro. Furthermore, all 3 GPUs were available.

Now investigating how to automate: force dGPU->logout->login chain. This could work with iMacs?

@goalque Nice. Got FCP running in similar vein. But iMac already has "dGPU" active given there is no iGPU, so technically a hot-plug > logout > login should work. If iMac user sees black screen on hot-plug - can log out by pressing ⌘+⇪+Q then return.

 

A way to set mux dynamically: here. Was hoping to find an easy command line option. There is a gpuswitch parameter in pmset too.

Update: This works:

sudo pmset -a gpuswitch 1

0 is integrated, 1 is discrete, and 2 is dynamic.

@mac_editor thanks again! found it. I had read your post in the past, but I missed the part about the driver version for the dGPU based Macs. I ran your script pointing to the specific version you mentioned, but I didn't get a chance to try it with the hardware yet. 

I want to say thanks again to both @mac_editor  and @goalque for all the clever hacks, and all of the support you guys have provided to us here. You guys are certainly doing a better job than Apple! 🙂

So I tried the patched driver, and it didn't work for me with the hybrid set up. 

I tried to give purge-wrangler another shot, with the appropriate driver version for my setup this time, per @mac_editor's suggestion and it worked. I had this going before, and I had posted something a few weeks ago where Ableton Live was not functioning properly when I was using purge-wrangler before. It now seems to be working fine so it looks like this driver thing got me to a good place.

The only issues I have is that the internal display seems to still be present when I close the lid, but from what I can tell that's normal?  

Anyway, thanks again!

@DannyVegas Please describe what didn't work and what you did, what does the boot log says (in misc folder, debug flag set to true)? Did you reinstall macOS?

@mac_editor, you said that it worked for you 100%. Did you try the public version?

@goalque had tried the version prior to release. Don't recall exactly. Will try public release and update with results. Though mainly you've added more config options.

@goalque I actually just ended up using purge-wrangler, as I wasn't able to get the automate-eGPU.sh hybrid solution working.

When I was trying to get automate-eGPU.sh going I did start from a 100% clean install. The disk was erased and a new install of MacOS was installed and automate-eGPU.sh was the very first thing I did after the OS was ready. My post above from last night has all my steps. Unfortunately, I didn't take any steps to capture diag info, but it looks my there is stuff in my syslog I'm happy to send you the whole thing if it helps.
