It's not empty. It's using more than one line. Use a text editor like BBEdit.app to look at it. It looks like this:
Code:
<key>IOPCIMatch</key>
<string>
0x17c210de&0xffffffff
0x220410de&0xffffffff
</string>&0xffffffff can be excluded because that's the default (0xffffffff matches every bit).In my Info.plist, I guess it would be added like this:
Code:
<key>IOPCIMatch</key>
<string>0x17c210de 0x220410de 0x220610de</string>Are you using Catalina? I use the attached script to install the kext:
Code:
source ~/Downloads/KextUtil.sh
installkext FakeNvidia.kext
rebuildkextcacheAh, yes you are right. Opened it first in XCode so I did not see this. OK, so I left the existing entries, and added another one for the 3080, like so:
Code:
<string>
0x17c210de&0xffffffff
0x220410de&0xffffffff
0x220610de&0xffffffff
</string>Yes, am using Catalina. But no matter what install method I use (also tried your script), the kext is accepted for inclusion in the cache, but not loaded. Also I have the following console message when I try to manually load the kext:
Code:
standard 16:15:23.049216+0100 kernel Notice - new kext com.joevt.driver.FakeNvidia, v1.0.1 matches prelinked kext but can't determine if executables are the same (no UUIDs).Any ideas?
I tried your KextUtil script and got the message:
So far, so good. After rebooting the login took a lot longer, and the screen went black in the middle of it. That *felt* different.
But still: kextstat | grep -v com.apple does not yield a result.
Any ideas?
Code:
Kext with invalid signature (-67062) allowed: <OSKext 0x7f9f857ef600 [0x7fff88f5bcc0]> { URL = "file:///Library/Extensions/FakeNvidia.kext/", ID = "com.joevt.driver.FakeNvidia" }So far, so good. After rebooting the login took a lot longer, and the screen went black in the middle of it. That *felt* different.
But still: kextstat | grep -v com.apple does not yield a result.
Any ideas?
But there is a major difference: sleep mode "kind of" works... at least the display goes off, and "waking up" does not crash it. But it does not really sleep either, at least the lights on the USB components are still on and the computer fans are still audible.
UPDATE: seems joevt's solution seems to work anyways! So the messages regardin kext not being loaded may be misleading. I too noticed the longer black screen on boot, so I thought something must have been happened.
So I just put the MP into sleep, and guess what! It woke perfectly! Maybe you just try the same?
Edit: just saw your message, and at least for me it seems that the machine is able to totally shut off.
Maybe others with 30XX sleep problems (apparently that affects all cards) can try this route as well, and see how it works?
Edit2: so there is another hint that this is actually working, just look at the ioRegistryExplorer (screen attached)
Now, the quesion would be if this runs for Big Sur as well, but apparently on Catalina it does!
joevt, you might be the true hero of the day!!! I thank you soooo much!
OK, I will do some further testing, and see if there are any other side effects. Will let you know how it went!

Yes, totally! I.e. fans shut off completely with no noise coming from the machine anymore. Will now try if automatic sleep also works, but manual does definetly. I just tried it several times, and it works perfectly, also wakes up pretty fast (hwoever, taking it into full sleep seems to take a bit longer than before, you might need to wait a bit)Haha, one second faster than youDoes yours "really" sleep?
Update: while manual sleep works, automatic sleep does apparently not, i.e. only invoking display sleep (but also being able to wake from it). Issuing
Not sure if this is due to the FakeNVIDIA kext. Any ideas?
pmset -g assertions gives me the following:
Code:
Idle sleep preventers: IODisplayWranglerkextstat doesn't show codeless kexts because a codeless kext points at a different binary for the code. In this case, we are using the binary that includes the IOService driver, which is the base for all other drivers. The binary is com.apple.kpi.iokit.
Yes,
ioreg -rn FakeNvidia will tell you if it got loaded.There must be some driver that is modifying the properties of the GPU device without attaching to the GPU device (for example, the name is changed to "display", and there's properties like "connector-type", "hda-gfx", and "NVDAType").
I would try removing all the NVIDIA drivers, starting with NVDAStartup by itself. Restart. Test. If good then stop, else also remove NVDAResman.
NVDAStartup matches GPUs belonging to Nvidia. It sets "NVDAType" to "Official". I guess it must also set it to "Unsupported" when it sees that the GPU is not supported.
About the IODisplayWrangler,
the following command
may include the Nvidia GPU in the GPUWrangler section and displaypolicy. Hopefully, removing the NVDAStartup kext will remove that.
the following command
/System/Library/Extensions/AppleGraphicsControl.kext/Contents/MacOS/AGDCDiagnose -amay include the Nvidia GPU in the GPUWrangler section and displaypolicy. Hopefully, removing the NVDAStartup kext will remove that.
OK, understood - thanks. And by the way... thanks for all your support, you have been of great help!
What do you make of this though? It says !registered and !matched... (but obviously it somehow worked)
Code:
ioreg -rn FakeNvidia
+-o FakeNvidia <class IOService, id 0x100000aae, !registered, !matched, act$
{
"IOProbeScore" = 30000
"CFBundleIdentifier" = "com.apple.kpi.iokit"
"IOProviderClass" = "IOPCIDevice"
"IOClass" = "IOService"
"IOMatchCategory" = "IOFramebuffer"
"IOPCIMatch" = " 0x17c210de&0xffffffff 0x220410de&0xffffffff $
"IOName" = "FakeNvidia"
"IOPersonalityPublisher" = "com.joevt.driver.FakeNvidia"
"CFBundleIdentifierKernel" = "com.apple.kpi.iokit"
}Oh, and in the meantime I have tested the MSI 3090 Ventus that - according to some other user - should work with sleep mode.
However: it does not. Same error as with all the other cards... so I will stick with the "FakeNvidia" solution.

Type
ioreg. You can see that many entries are not registered and not matched.
IOService | Apple Developer Documentation
The base class for most I/O Kit families, devices, and drivers.
registerService | Apple Developer Documentation
Starts the registration process for a newly discovered IOService object.
In my ioreg, only the following exist:
Code:
registered, matched
!registered, !matchedWhen the IOService is registered, then matching can happen, and when all the matching is done, then matched is true.
The source code for IOService is available at opensource.apple.com
Yep. You're totally right. The fan noise is simply to tame the excellent scaled CPU usage. It looks and plays beautifully on this setup. I'm getting a buttery smooth 60fps (v-sync) at 4K resolution (with Digital Foundry settings).
1-2 weeks in and I'm absolutely loving the ASUS 3090 TUF OC in my 16-core Mac Pro. I ended up leaving the card voltage settings at stock. I also didn't touch the Mac Pro fan settings either. Everything is out-of-the-box "default". During gaming/full CPU load, the Mac Pro fan noise really doesn't bother me at all. Heck, if you've ever played any last-gen gaming console and had to put up with a relentless jet engine, then the gentle whirr from a fully loaded Mac Pro is pretty zen and soothing by comparison. If it bothers you, then you can follow Alex's excellent tips on undervolting along with custom Mac Pro fan settings.
I've also been loving the Moshi USB-C to DisplayPort Cable (from the Apple Store). It doesn't require any connector shaving/hacks to fit into the DisplayPort on the card and it looks premium alongside the Pro Display XDR. I've come to realize that the lack of brightness functionality in Windows 10 isn't an issue for my setup. I just make sure my brightness is set to max in macOS before booting into Boot Camp and it's ready for max brightness gaming. Easy.
My Belkin Charge and Sync Cable (for Huawei VR Glass) arrived from China but I'm not crazy about it TBH. The outer cable sheath does that weird rippled (saggy skin-like) bending that some cables do. I also don't like the plastic connector (that will need shaved/hacked) to fit into the DisplayPort on the card. The whole cable feels cheap - and yes, it's a Belkin genuine cable. The cable is also REALLY long. This might be really good for some setups, but it just looks messy under my desk. I'll probably sell it on and continue to use the Moshi cable.
As much as "Cyperpunk 2077" and other titles such as "Control" look mind-bindingly amazing, I've been mostly floored/blown away by digging into the world of emulation. "Breath of the Wild" on Cemu (Wii U Emulator) at 4K/60fps (v-sync) is simply stunning.
PS. Since installing Amphetamine (Mac App) I haven't had a single issue with sleep issues/black screen of death under macOS.

Interesting, for me it was more like the middle fan that was relatively loud. And at the same time the 3080s fans were relatively low, so it felt like the MPs fans were doing the work for the GPU. First, I nailed the middle fan to 500RPM (by using macs fan control) and then the 3080 fans really ramped up, to the point of being annoying. To balance things out I have set the middle fan to 750RPM, so it delivers enough fresh air to the GPU, and also helps with overall cooling. Also I removed some PCI covers to help the 3080 FE airflow.
The result is that now, while all fans ramp do up when being under load (also cyberpunk in my case
none of them do so much that is really loud or annoying. GPU still stays under 75 degrees all the time (Cap is always power limit, not temps) and I guess I even have some headroom for overclocking without the machine getting really loud.Resume: the MP 7,1 is one of the most silent gaming PCs on the market
(and that while being air cooled!)
You also could go with the FakeNVIDIA kext discussed in this thread. So, you get at least display sleep back, and also manual full sleep without any crashes. Only thing not working right now is autosleep, but as soon as I have some time I try to find a solution (also thanks again to joevt for all his work and help!)
If you mean the 3090 FE: it won't fit anyways, so stay away. If you have some 3rd party 3090, it depends on the manufacturers cooling solution. All I can say ist that the 3080 FE is quite good with noise levels, but you may need to tweak the MP fan settings to get best results (see my post above).
Yeah, the MP should be able to handle it (not sure about 2x 3090 though, are there enough power connectors?)
The main problem is more on the macOS side, where you will definetly loose some sleep / power management abilities. Hope this also can be solved / improved.
