I've tried posting elsewhere but it was removed. I have 2 4,1 dual tray and 2 5,1 dual tray fully working Mac Pros. I am giving them away. Not for sale or trade. Free. Mid Missouri. If no one wants them, recycle it is. Not trying to violate any rules, just trying to give these away. Surely someone will want to continue the life of these machines.

This is completely off topic, so I probably shouldn't really reply, but assuming a good faith attempt to find some people who might want them: if you want to continue their life, why don't you sell them? They seem to be worth something, and more than it would cost you to post them, on eBay. So you get them to a new home and maybe get a few dollars out of it, hopefully enough to cover your time!
 
It's normal after Monterey startup the PCI and Intake fan's spin a tittle bit higher and after 8 minutes, or so, they return to idle.

Cleared NVRAM a couple of times.

Currently have OC set up to use either Mojave or Big Sur, I want to perform an OTA update from Big Sur to Monterey.

Which option applies, 1 or 2, from the main page of the guide instructions, it seems both options apply? many thanks

Recommended update options:

➊ Clean install with installer app in macOS Mojave and later, or OTA update in macOS Big Sur and later
SecureBootModel is set to Disabled
VMM flag is enabled
➋ Clean install with bootable installer, installer app in macOS Big Sur and later, or OTA update in macOS Big Sur and later
SecureBootModel is set to Default
Hybridization is used
Firmware features are updated

Help please. I'm updating from Mojave to Monterey on my Mac Pro with an RX 580. I've done the process exactly the same way as on my other identical machine.

However, when I reboot into OpenCore, the Mac Pro starts its usual process, but instead of what normally happens, the CD tray opens and stays open. While holding down the Option key, the tray does not retract and the boot picker never appears.

I've done this before on my other identical Mac Pro, which also has an RX 580 configured the same way, but on this machine the boot picker doesn't show up no matter how long I hold the Option key. If I release the key, the CD tray closes and the Mac boots normally into Mojave.

It's been a while since I last did this, so I'm probably missing a step.

I've also disabled SIP, but that didn't help.
Thanks

Are you absolutely sure that this GPU even have pre-boot configuration support, also the Mac Pro have EnableGop?

Did you installed the no BootPicker GPU to the working Mac Pro? Do it first.

Btw, this is not the thread for this type of question…

Thanks Alex.

Probably have you clean the ROM on this one as well.
I saw here manually OCLP.

Sorry the wrong post.

Well I pulled my working RX580 out of my main working 5,1 and it does the same thing.

I guess I missed the EnableGop. The main RX580 which I tried swapping, did not work as I mentioned, but I never had to enable the GOP for some reason?

Can you steer me the right post to enableGop please, thanks, and sorry if I was in the wrong post.

Send me a PM with the files required, see the PM thread, I'll take a look.

This is thread for manually installed OpenCore, not OCLP or problems related to missing pre-boot configuration support.

You have something unrelated to OC or even OCLP, the most probable is that you have a non-flashed or worse, a mining modified RX-580.

So, if your GPU is not 3rd party flashed (MacVidcards and etc) and you never injected the EnableGop EFI module to the Mac Pro BootROM, you never had pre-boot configuration support with this specific Mac Pro and probably never had it complete the OCLP install procedure (which requires a working Apple BootPicker to boot from the OCLP installer) with this Mac Pro.

You have to solve the issues with pre-boot configuration support and the GPU first. Repairing the BootROM and having EnableGop is the first step.

Hi Forum,
I am in a bit of a pickle.
I had a mid 2010 that just went south after many moons of great service. I was running OCLP on an NVME with Sequoia installed. I had a spare Mid 2012 handy so I took the NVME's and installed them. I have two NVME cards in the machine. The 1st one has The sequoia install and the other is a new blank. The 2nd has my old Mojave install that I was using before the joys of OCLP. So I popped the Radeon RX 580/8gb and the two NVME blades. Rebooted the mid 2012 and its booted fine into Mojave. I downloaded OCLP 2.4.1 and installed it on Mojave and selected Mojave for the EFI when Prompted. I also made two installers for sonoma and sequoia on separate 64MB USB keys. I disconnected all of my Sled Drives and rebooted as per instruction and help the option key. No Reboot just a whitish screen that goes nowhere and when I press the power key it powers off. I have tried a myriad of combos to see if I can get it working. THe install process was a breeze so I at a loss at to whats happening.
I am wondering if it is the blades??. I have a USB 3.0 card in one of the PCI's as well. Is it the keyboard?
Apologies for all the screens.

Ahh so the post patches are for the EFI. I thought that they went in after the new system was up and running. I will try that asap.
Thanks Basslik

You were right, post patches are for macOS, most of the post patches are drivers/kexts/plists for supporting obsolete hardwares removed by Apple with the unsupported macOS releases.

Thank you tsialex. Helpful as always. I am thinking of barebones approach. Strip it down to just the ram, graphics card and the two nvmes and see if that brings it over the line.

WHOA, this makes absolutely no sense. As you know, I tried installing OpenCore many times and could never get the EFI boot screen to show up for the life of me. I knew I'd probably have to inject the GOP, but man, I'm not that versed in those kinds of things.

So I went Jesse's Flying route (install), and holy moly—it was too easy! 😍

I built a Monterey USB installer with OpenCore on the same stick (the usual). With no drives installed, I plugged in the USB installer with OpenCore, powered up, and reset the PRAM after hearing two chimes. I released the keys, and then the EFI boot option showed up (WTH), thers no GOP. I immediately shut down the computer, installed the new SSD in slot 1, and the computer booted right back into the USB installer with Monterey, and not the EFI screen I just saw.

Monterey installed without a hitch. I did my post-install steps, and this is where it gets really weird. After another reboot, OpenCore asked me if I wanted to install the bootloader on the drive so I wouldn't have to keep the USB stick plugged in. Then it prompted me to reboot while holding down the Option key and follow the usual process of assigning it to the drive.

Well, here's where it gets totally WEIRD. BACK TO THE SAME BOAT.

I installed OpenCore to the drive, removed the USB stick, and held down the Option key, but the EFI boot option would never, ever show up so I could assign it to the drive. Even when I put the USB stick back in and tried again, it still wouldn't appear—only the Monterey boot option showed up. I held the Option key down for a long time both ways. (I GAVE UP.) I just left the USB stick in.

I then removed the USB stick, and for some reason it automatically booted without the EFI boot screen. How it installed on the drive ???

So now there's just the two MacOS's that pop up without a EFI boot screen. Yes, I also installed Sequoia, and the same thing, never an EFI boot screen????

ALL GOOD, just two macOS options to choose from.
