Hi Neil
The latest official OS was Mojave macOS 10.14.6 with a recommended Metal-capable graphics cards, look at Apple's website using older OS Versions https://support.apple.com/en-us/HT211683

I had a copy of High Sierra in my Applications folder, I put that on a formatted thumb drive and was planning on using that to reinstall the older OS.........problem is I don't know the steps to follow to be able to do that

Search the web with "how to install high sierra from usb" you will get tons of answers, even YouTube videos.
You have to make a bootable installer for example with balenaEtcher, then boot from that usb stick and do the install process.

I found a step by step guide but part of it was to go into terminal and type sudo /Applications/Install macOS highsierra.Sur.app/Contents/Resources/createinstallmedia –volume /Volumes/MyVolume but got scared when I saw that.
Let me see if I can find it on YouTube

I wish you good luck.
p.s. as this thread is for installing/using OpenCore on MacPro you should ask/find infos for your problem in other threads. As said before, the web is plenty with infos related to your situation

Now OpenCore Legacy with Monterey on ssd - Same windows on ssd but no boot, Mojave no boot up too

I can't boot on Mojave, chimp and the Mac stop after, when I choose it from preference. I can't boot on windows, no saw windows on preference system, If I try to make bootable windows with paragon, I see the windows on preference system but error 104 appears and no boot. No boot expo Monterey from console recuperation. I don't try to boot from apple boot because I must replace my rx 580 by a CG compatible.

I just want to boot On monterey or Windows, and if somme one know how to have a boot screen with sapphire RX 580
Thanks for your help

Just wanna give my 2 cents, OCLP had an update to 0.4.4. Updated OC and Updated from 12.2 to 12.3.1 with no issues. <phew>

@cdf What's the best approach to "transferring" my OC setup or reblessing a different drive in my cMP?

I've been having issues with my Samsung QVO drive, and @tsialex confirmed that modern macOS does not work well with QLC NAND (11.6.5 and Monterey), so it will likely fail to boot soon (which explains why I'm seeing prohibitory symbols and getting apple logo half load crashes every 4-5 boot attempts), so I want to move everything I have onto a Crucial TLC drive that I have just acquired.

Going to install a fresh Big Sur 11.6.5 onto it today, along with migrating all of my things over, and then bringing my 0.8.0 OC into that drive's EFI, but I want to understand what the best way to rebless it would be (I am going to remove all of my other drives, because when I updated to 11.6.5, macOS wrote things to my Windows 11 drive, and I ended up having to start from scratch, of course, it was sitting in SATA bay 1, and I had my macOS in a PCIE slot, so my boot order was different, but i've corrected that issue now):

1. Could I simply bless my new Crucial drive from within the Samsung QVO, since I would need to use the Samsung to get into macOS? (How else would I get into my machine with the RX-6800XT installed)
2. Would I need to do anything to unbless the QVO, or does simply blessing another drive override/take care of it?

FYI -- this is not the thread for OCLP. There is a separate thread for that.

When you bless your new EFI (Crucial) it becomes the boot drive - you do not need to do anything with your Samsung QVO. After you bless the Crucial you can delete the data in the EFI partition on the Samsung.

Thank you!!!!

Yes, but there's a catch. Since you're booting through OC, you need to disable RequestBootVarRouting before blessing your new drive. Otherwise, the blessing is actually for booting through the original instance of OC!

Yes, but there's a catch. Since you're booting through OC, you need to disable RequestBootVarRouting before blessing your new drive. Otherwise, the blessing is actually for booting through the original instance of OC!

So the config.plist on QVO needs RequestBootVarRouting = False

But the config.plist within Crucial will have RequestBootVarRouting = True

Then I bless Crucial while booted into the QVO, and after reboot, it should boot into Crucial (after I choose it in OC Bootpicker), yes?

AFAIK, it's not modern macOS, but macOS in general. QLC drives currently in the market are drives designed to be used more for archival purposes (small number of erase-write cycles, lot's of read operations), so, these drives (Samsung 870 QVO, Crucial BX500 and several others) don't work well/don't have endurance when used as boot/main drives.

Recently several people are having more problems than the usual and long known issues with QVO drives, like not being recognized after a warm boot. The dumps I had a look had dozens of BootXXXX variables that stopped appearing when the QVO drive was removed and the BootROM re-flashed with a never booted image, so I think that is reasonable to suppose that something related to the QVO drives is making a mess with the boot related variables.

Correct. Of course, make sure to reboot at least once after setting RequestBootVarRouting to false.

Hello,

I did try to update my current BigSur OS 11.6.2 to the latest version 11.6.5 but fail after updating my config file. My machine started to be on a boot loop.
I've OC 0.76
attached my bugy config file (do not try to use it) + log

Then I did copy my back up config file and was able to boot as expected.

However I've one question regarding OTA update which solution should I select between the two options listed in the post 1

➊ Clean install with installer app in Mojave and later, or OTA update in Big Sur and later

• SecureBootModel is set to Disabled
• VMM flag is enabled

➋ Clean install with bootable installer, or installer app in Big Sur and later, or OTA update in Big Sur and later

• SecureBootModel is set to Default
• Hybridization is used
• Firmware features are updated

I did try the option two knowing my nvram was clean but fail.
Tomorrow will try the option 1, however might be happy to hear your POV about your config setting for those who just update bigsur from 11.6.x to 11.6.5.

Thanks

 

[superparati]

Method 1 was the right one for me.

• SecureBootModel set to Disabled
• VMM flag enabled

My cMP is up to date under Big Sur.

Then we have confirmed that both methods work as cdf documented for BigSur. See my post #10,861

Re: basic setup…

First boot

If your Mac has native boot-screen support

➊ Reboot and hold Option to enter Startup Manager.

Cannot boot into Startup Manager.
Nor can I re-start into Recovery mode.
I only get startup chime and endless Black Screen (approx 25 min wait); keyboard Caps (green) light responsive.

Any suggestions?
i.e. Need to rollback gfx card before proceeding?

Edit1: I can restart back into 10.14.6 just fine; any workaround suggestions to proceed w Open Core install?
Edit2: Now I can't get newly created EFI partition to mount (in Finder) again? Terminal error msg:

Volume on disk0s1 failed to mount
If the volume is damaged, try the "readOnly" option

fyi: my boot partition is NVMe

Hello, I am really looking for some advice on my Mac Pro 4,1 -> 5,1 firmware updated (originally 8 core 2.26 Ghz; 2x E5520 chips, 17GB RAM) and now running Big Sur using OCLP 0.4.3 version. I managed to upgrade the CPUs to X5680 (delidded) as well which was scary to say the least for me (now 12 core, 3.33Ghz Westmere!). The GPU is the default NVIDIA GeForce GT 120 and I installed patches post OCLP for graphic acceleration. I use the Mac Pro for photo editing (no videos) - lightroom and photoshop. These all seem to be working fine but photoshop complained that I am using a non-metal GPU but seems to be working. I have a Sapphire Radeon RX580 8GB and the power leads with me but I am not sure if I can simply switch the default GPU to this Radeon? The questions I wanted some advice on were
1. Can I simply remove the current default GPU and switch to this Radeon RX580 or do I have redo the OCLP?
2. I will lose the boot screen as it is not a flashed GPU, right? Is it better to get a similar one from macvidcards europe at exorbitant prices instead of this non flashed RX580?
3. I have 2 hard drives (another HD running High Sierra) and hence getting a boot screen is important for me. Is there a way to get boot screen with RX580 and Mac Pro running Big Sur with OCLP 0.4.3 (dortania/github)?

I am quite happy with way the computer is running currently and if the RX580 will destabilize this setup, I won't upgrade the GPU at all.
Thanks very much in advance and best wishes

Cannot boot into Startup Manager.

Is your graphics card (the RX 580 mentioned in your signature) flashed for Mac? If not, then you'll have to follow the instructions below the heading "If your Mac has a standard graphics card" (this is what most people have to do).

Nor can I re-start into Recovery mode.
I only get startup chime and endless Black Screen (approx 25 min wait); keyboard Caps (green) light responsive.

If Command-R doesn't work, then try the Terminal command from macOS as described in the guide. Unless your Mojave installation is broken, you should be able to get into Recovery. Resetting the NVRAM and choosing your Mojave drive in System Preferences > Startup Disk and rebooting first may help.

i.e. Need to rollback gfx card before proceeding?

No.

Volume on disk0s1 failed to mount

Did you verify that disk0s1 is actually your ESP with the "list" command first? The identifier can change from one boot to the next.

OpenCore configurator shows the drive with the bootloader, which can be easily mounted:
