Both correctSo do I understand from your comments that the flashed rx590 could be used because the boot screen works before OcLp, and that OCLP would not create any code that would damage the card?
I currently have a NVIDIA GTX 680 flashed for Mac installed. I had Monterey up and running with OCLP with root patch for Kepler card. Monterey update 12.6.8 corrupted boot partiton so I had to revert back Mojave TM backup. Can't get OCLP to boot anymore so I want to install a Sapphire Radeon Nitro+ RX 590 and Martin Lo OC to reinstall Monterey 12.6.8.RX590 can work in Monterey natively, not extra driver need (in fact, no drive for you to download and install).
However, your cMP isn't support Monterey natively, you have to use OpenCore to install that.
Some users used OCLP to install Monterey with their old graphic card, then the root patch may lock the OS with the old GPU. You should avoid this.
Boot screen is not OS related, but firmware / boot loader related. Boot screen works before OS start to load.
Can, but you have to manually turn on VMM and disable SMBIOS in the OpenCore config.plist.can I use your OC to install Monterey 2nd drive with the RX 590 installed?
It should. If no boot screen for whatever reason, 99% can be fixed by downloading a factory ROM from TechPowerUp, then flash your card back to factory state.If so, will your OC package give me boot screen support with the RX 590?
Thanks. I ordered an non-flashed Sapphire RX580 because it's less power hungry and is 40mm thick compared to the 590 Nitro which is 43mm thick. This way hopefully I'll still be able use PCIe slot 2 with a riser cable for my NVMe SSD. Currently I'm still using a flashed GTX680 (38mm thick) and trying to install MLOC onto a bootable thumb drive. I installed a fresh copy of Mojave onto the thumb drive, reset NVRAM and disabled SIP but can't bless OC. In recovery it shows successfully disabled SIP but when I reboot I see it's enabled with custom configuration.Can, but you have to manually turn on VMM and disable SMBIOS in the OpenCore config.plist.

Please completely disable SIP to run the bless tool.Thanks. I ordered an non-flashed Sapphire RX580 because it's less power hungry and is 40mm thick compared to the 590 Nitro which is 43mm thick.

I've tried at least 20 times over the last few weeks to disable SIP but cannot make any changes to SIP. I've even tried entering individual commands, e.g. "csrutil enable --without nvram" but I am unable to make any changes. I've followed the precedure multiple times, I reset nvram (chime 3 times), then boot into Recovery and disable SIP successfully but when I reboot normally, SIP does not save commands. Something happened when Monterey 12.6.8 security update crashed the boot partition. I was able to disable SIP and install Monterey using OCLP over a month ago but after the crash, I had to restore a TM backup of Mojave without OCLP. Now every time I try to disable SIP it does not save changes. There is very little info about this issue on the Web, I can't figure it out?Please completely disable SIP to run the bless tool.

EDIT: After researching I believe my system's SIP status shows my last configuration that was implemented by OCLP before 12.6.8 security update crashed OC boot loader when I had Monterey installed with Post-Install root patches. SIP is now now locked into that configuration somehow? I can't reinstall OCLP to disable SIP as I would have to first disable SIP to install OCLP.
EDIT 2: Typed nvram -xp in Terminal.
No "csr-active-config" or "efi-boot-device" ?
Should they be listed?View attachment 2246437
Yes it is flashed. Can you explain what you mean? Boot into what? Are you referring to my screen capture above where I'm booted into Mojave thumb drive where MLOC is loaded?Your GTX680 is flashed?
If yes, you can simply hold Option key to boot, and use Control + Enter to "bless" OpenCore (the EFI entry in that boot manager).
If you are already running my package. Then you don't need to run the bless tool. It's already blessed.Yes it is flashed. Can you explain what you mean? Boot into what? Are you referring to my screen capture above where I'm booted into Mojave thumb drive where MLOC is loaded?
These are my options at boot screen:View attachment 2246505
No, I have not been able to get that far. I can't bless OpenCore so I could not run your package.If you are already running my package. Then you don't need to run the bless tool. It's already blessed.
And SIP is controlled by the OpenCore config.plist. That's why you can't disable it in recovery partition.
No, I have not been able to get that far. I can't bless OpenCore so I could not run your package.
But your "current boot screen" is the OpenCore boot picker, not the native Apple boot manager.Yes it is flashed. Can you explain what you mean? Boot into what? Are you referring to my screen capture above where I'm booted into Mojave thumb drive where MLOC is loaded?

OCLP have stopped issues being reported since Feb '22. He said "With the situation going on back home in Ukraine, I've temporarily disabled new Github Issues so I can focus on my family. I am currently the only active maintainer with these issues so there's no one else to delegate them to."Opencore legacy patcher recovery boot loop seems to be a major problem in OCLP..
´there are a lot of threads about it @ forum here, and I can´t read about a solution, threads seems to be abandoned...
I´m stucked with same problem here, have spent whole weekend trying to solve it, without sucess...
At Github, some reports about are simply closed by khronokernel, without a response from original poster...
Sorry needed to get some sleep and clear my thoughts. I've been researching this for 2 weeks, 2 weeks of pure frustration.But your "current boot screen" is the OpenCore boot picker, not the native Apple boot manager.
You are already running OpenCore. OpenCore is already blessed.
I'm assuming you mean ROMTool? I just dumped it but don't know how to open it. I zipped it. DeletedOne can run my dumper and see what bootloader is blessed and where it lives.
I have a thread there, "Missing EFI Boot Option" about this issue but have not received much feedback.OCLP have stopped issues being reported since Feb '22.

The only direct way to get support is to get an account on Discord and post there. Good luck there.
That's why I said "Good luck there". It's easy to get drowned out amongst the noise thereI have a thread there, "Missing EFI Boot Option" about this issue but have not received much feedback.

No, the tool in my signature.I'm assuming you mean ROMTool? I just dumped it but don't know how to open it. I zipped it.
Dont post your rom file, it contains private data!I'm assuming you mean ROMTool? I just dumped it but don't know how to open it. I zipped it.
