From the GitHub repo: "Note: Apple CPU identifier must be 0x0F01 for 8 core CPUs or higher and 0x0601 for 1, 2, 4, or 6 cores. This is the default in OpenCore for non-natively supported CPUs."

That's the key. I set my ProcessorType in SMBIOS to 3841 and I can change the CPU name.

I recommend doing it without the boot-args. I don't know how to escape spaces in revcpuname as a boot-arg. Wrapping it in double quotes didn't work, and neither did \ before the space.

Works like this in NVRAM. I named it Apple M1 once in testing as well.
Code:
<key>4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102</key>
<dict>
    <key>revcpu</key>
    <integer>1</integer>
    <key>revcpuname</key>
    <string>Intel Core i9-11900K</string>
    <key>rtc-blacklist</key>
    <data></data>
</dict>
Are you using ProcessorType in the SMBIOS or DataHub tab? I just tried setting ProcessorType to 1537 (0x0601) in the DataHub tab on my 6-core Comet Lake with both (a) RestrictEvents and (b) revcpuname/revcpu in NVRAM, but alas About this Mac shows a blank processor name. This is on Monterey, however.

Let's get back to basics:
  1. Are you running Big Sur at this time?
  2. Which kernel extensions are not loading automatically on boot?
  3. Have you tried reinstalling the applications that are associated with those kernel extensions?
Some comments:
  • In Big Sur the System volume is write-protected.
  • There is nothing we can or should do to the /System folder.
@CaseySJ,

I have been running Big Sur for some time.

It's a handful that won't "start" until I do a "sudo touch /Library/Extensions" then they all finish loading within a few seconds. These are the ones (that I can see) that aren't starting until that:

- HighPoint*.kext drivers - All my extended storage is on that PCIe controller
- RMEFirefaceUSB.kext - All my RME USB audio gear
- RMEPCIeAudio.kext - My RME TB device
- EnergyDriver.kext - For the Intel Power Gadget app

It's possible a few others are also not starting but those are the ones I definelty know need a "knudge".

I have tried re-installing them. Doesn't help. I'm going to try a few reboots post this kextcache execution.

Thanks,
Lam

I didn't use OpenCore Configurator to change it, but I did it in Generic, not DataHub.

Could also be that the patch doesn't work on Monterey.

:headbang:Many many thanks to all. Because of all you, I was able to build my first Hackintosh. I can actually work with large images and video without the painful lag I had grown accustomed to.

Question: Is anyone out there running dual 4k monitors?

Yes, I am running three monitors: (1) 4K LG TV, (2) 27" 4K LG Display, and (1) 32" HD Display with my Radeon 5700XT.

:) Thank you for the quick response. That is such good news! Did you run into any compatibility issues?
I am planning on 2 LG 32UL950-W tb3 monitors for my workspace. Or is DVI the better choice?

I think CaseySJ has warnings about Thunderbolt 3 monitors. You should see that somewhere if you search this thread. Displayport and HDMI monitors work pretty much without fuss though.

Hey, @jiffyslot,

what's with injecting the properties via OpenCore DeviceProperties?
That's the way, I do and it's also working on Big Sur / Monterey:

Good information. This is a more user-friendly approach than editing SSDT.
Where do you get the data from? These aren't shown in IOReg for me. Especially the data for efiversion and rom. I'd like to try this for a Sapphire RX590 SE 8GB.

Perhaps I might be dense but I do not see the SSDT for the Thunderbolt ports on the first page of this thread.
