yeah, it was on!May I know if the VMM flag is ON in your OpenCore config?
It should be OFF for daily use, which looks like this

Hello! I get the same problem. cMP4.1>5.1. I get “prohibition sign” after every reboot. Initial boot goes fine. But after reboot the loading line goes waay slow and then “prohibition sign”. This start up massage first occured on reboot after updating to High Sierra without any OpenCore.Today I just install Monterey although the installation is successful I still get trouble
I get Apple.com/startup help 3 times . I turn off pc and turn on it back pc continue installing
When I boot to Monterey I still get Apple.com/startup
Turn off and on it boot to Monterey . Do I made any mistake?
Monterey run so smoothly
Hello! I get the same problem. cMP4.1>5.1. I get “prohibition sign” after every reboot. Initial boot goes fine. But after reboot the loading line goes waay slow and then “prohibition sign”. This start up massage first occured on reboot after updating to High Sierra without any OpenCore.
Tried to solve it: 3x NVRAM reset. No luck.
Installed OC 0.9.2 + Monterey 12.6.6 on a clean drive. But the problem still presist. Is there anything I can do?
I'm finally going to make the jump from Mojave to Monterey on my Mac Pro (see my signature for current hardware). I'm running Mojave on PCIe SSD and I'm going to install Monterey on a SATA SSD until I'm sure I've done everything correctly. I plan to migrate Monterey onto PCIe SSD once I'm confident there are no issues.
I have a USB Razer mouse and an original USB apple keyboard connected currently and I'm hardwired to my router. I have no issues with Bluetooth in Mojave.
Questions:
I have a Nvidia GTX680 flashed with MacVidCards ROM which runs natively in Mojave. Are there any issues using Martin Lo's opencore with cards already flashed with Mac EFI?
Does anyone see any problems with what I plan to do above?
Yeah sorry, I had multiple tabs open scanning the forums here. I didn't realize I posted it in the this thread.The GTX680 is only supported upto Big Sur with the manually configured OpenCore package.
For Monterey and Ventura, you would need to use OCLP and not the manually configured OpenCore.
Besides, this thread is about enabling H/W acceleration of AMD GPU's.
The GTX680 does not support HEVC acceleration.
You would need to consider replacing it with an AMD GPU if you wish to have H.264 & HEVC encode & decode.
Two questions to this:Possible to run 8x32GB RAM in macOS (user need to mod the config.plist manually. Replace thefalse
belowCustomMemory
totrue
)
1) Only some 32GB DIMM can work, not all. So far, it seems only the 4Rx4 RDIMM can work. Speed shouldn't be a problem. The cMP should auto select the highest possible clock speed to run them anyway.Two questions to this:
1. Is this sufficient to get the 32GB-sticks to work right now or are there still exact specs (size, speed) to be entered in addition?
2. Does this any harm to systems where no "custom memory" (32 gig sticks) is installed? Any reasons not to keep it set to "true" by default?
Thanks in advance for enlighting me! 🙂
I ordered what (i think) some others had success with. So i hope from the hardware-point the modules should work. Will likely arrive today!1) Only some 32GB DIMM can work, not all.

So it does, if only "CustomMemory" is set to "true" and no other edits are made? And also the full amount is really made use of?2) There should be no harm to do so. In fact, that memory spoofing is quit cosmetic, you can set that to 12x128GB etc, and the cMP will still run. However, set that to spoof to 32GB DIMM somehow magically make the cMP can really boot to desktop with 32GB DIMM in macOS.
So far, no tester can make the cMP crash by spoofing the memory config (as long as the RAM itself can actually work). And apparently the cMP can use all memory regardless you spoof it to higher / lower capacity.Thanks for your reply!

Hello. I have a MP 5.1 with a 5700xt, Monterey and OCLP. I noticed it is unable to encode HEVC 10bit through HW accelerate, either in Compressor, Resolve or Quicktime. Did I miss something?
Changing MinKernel to 19 for the GPU kexts worked to allow me to boot into Mojave - the screen blanks out where it used to crash, but then the progress bar reappears and it continues.You may disable all GPU related kext for Mojave only in OpenCore config by setting the min Kernel.
However, if that's too complicated. I think you better go for RefindPlus. So that you always default boot to RefindPlus, then you can select native Mojave, or OpenCore to further bridge boot Monterey.
Or you can simply flash you cMP
Therefore, your cMP default to boot OpenCore + Monterey. And you can simply hold Option key to boot native Mojave on the day you need it.
There is actually a mac 4,1 and 5,1 compatible card that will give you blazing fast Wifi and Bluetooth if you have a card free. The card is powered by USB. Make sure to route the power cable from PCI card to USB.2.0 not any 3.0 cards you may have installed. The mac will instantly recognize it. Just make sure to tell the mac that you aren't using the native cards anymore or simply take them out.

I now have a Hideez Bluetoth Dongle working in Monterey (note - it just needs the BlueToolFix entry set to true in the config.plist).
BUT I don't have bluetooth available for the boot screen picker! Is there a trick?
I currently have OpenCore installed on USB.
EDIT - OK - i wish I havd known this before buying the Hideex Bluetooth Dongle and waiting for it to arrive patiently - for bluetooth at bootscreen time you need a bluetooth module with HID Proxy.
I've now ordered a BCM943602CDP, adapter card, pigtail cable and antenna from aliexpress. Fingers crossed all the bits are correct.

Yep, no problems here either.12.6.8 update seems safe to apply. Very straight forward update with VMM on and SMBIOS spoofing off.
