MP 1,1-5,1 Manually Configured OpenCore on the Mac Pro

[trifero]

I'm sorry but there AREN'T ANY working drivers for the RTX series on macOS, period. Even if VESA mode was somehow possibly enabled he'd still be without any form of hardware acceleration. Btw this is not me, but the advice given by the Opencore team.

View attachment 2065465

The reason its not appearing in the OCLP boot picker is likely because the Lilu/WEG they are using in the build doesn't have the necessary parameters set for the RTX cards, hence no support. So my suggestion is if he wants to get acceleration for both Windows and/or macOS in his work is to swap the card for a RX6800 or RX6900XT.

The RX works. Right?

Yes correct. RX is AMD. RTX is Nvidia. Nvidia is largely not supported now, especially after High Sierra 10.13 (GTX 1080 Pascal was last major lineup supported) and certain macOSes afterwards such as Monterey with Kepler. Ventura has even less Nvidia support (hardly any) which is why most will need OCLP to work. That said Dortania is working hard to provide legacy Mac Metal support which was reported in active development recently.

Thank you so much, sir. It also has two displayports, that is what I need to replace my start failing Radeon HD 7950. It´s better card, isn`t it? Also I can see that the no flashed for mac are much cheaper. But I will not have boot screen, right?

Please excuse the rest if I`m asking this here. I`m a bit lost.

 

[sfalatko]

Yes it is a better card (faster) than your 7950. You will not have a native Apple boot screen but with OpenCore you can have a boot screen.

I have two CMPs, one has a updated broadcom bluetooth card and the bluetooth and WiFi for monterey works without kexts
on the second, an old bluetooth card (Atheros) - which worked on catalina, but there was no Wi-Fi on BigSur and on Monterey and the kexts did not help.
on the second cMP i use ethernet and use wired keyboard and mouse
how to try to get wifi using kexts: watch the corresponding video on Martin Lo's YouTube channel

Thanks GH, Ive actually already attempted Martin Lo's Config Mods but with no success. I don't understand how the Original Airport Card I have installed still works in Catalina but not in Monterey, even after using the Config Mods and the OCLP Root Patcher.

I think I F up. I need your help. I'm new to this.

I have Early 2009 flashed to 5.1 with RX580 and open core 0.6.7 Martins Package running Mojave (I have built this few years back and it is amazing machine) everything was working super well I even installed newest security update today.

I wanted to create BigSur Installer so I downloaded and run newest OCLP I hit “Built and install open core” then “download macOS installer” I selected 11.7 and it downloaded for me BigSur installer in to application folder.

Next I was not thinking. I clicked “Built OpenCore” button, and “Install OpenCore”

I was presented with my disks (I have SSD with Mojave and 4 other disks in two Raid 0 as scratch disks and 4 other disks RAID 5 connected via USB.

I selected my SSD disk 0 then I selected partition (I have only one partition on that disk) I was told to reboot with Option key.(It looked like OCLP is getting installed on to the SSD properly)

When I reboot with Option Key I hear chime and nothing happens, screen is black, when I reboot again and do nothing, I see gray circle crossed and mac shutsdown.



I'm panicking, I did use carbon clone to clone my SSD on to USB drive but my boot menu doesn't show up.

How I can fix it, any suggestion would be greatly appreciated.

Thank you so much.

Hard as it may be to believe, this isn't an OCLP support thread, and most users of the method advocated in post #1 know next to nothing about OCLP. You might want to search for an OCLP support group to get knowledgeable answers.

Thank you very much, at this point I would apreciate help with any method. Any sugegstion what would be the quickest fix, I can't boot in to recovery mode Command R brings up circles crossed out and mac shuts down, and when Holding Option key mac is stuck at black screen.

 

[PeterHolbrook]

^Are you using a (Metal?) GPU that was provided officially by Apple, or one that was retrofitted and that is or used to be able to display a boot menu?

If I understand correctly, you installed OCLP with the intention of updating to Big Sur but are still running Mojave. The problem with this is that OCLP doesn't support Mojave. I would first try resetting the NVRAM to boot Mojave natively. Note, however, that OCLP might still get picked up as the default boot option. In this case, another machine or another disk with Mojave can be used to get things back to normal.

you need to remove the disk with efi, where you installed opencore or oclp
connect it to another mac (if you have special adapters, you can connect it via usb to ssd)- You have RAID via USB- put it instead RAID
open the efi on that disk (you can use the clover configurator- Marin's OC has it) download a normal opencore, as in post # 1, edit important parts in config file (as in cdf the instructions).
put new opencore in efi
insert disk back - should work
there is a second way - everything is the same, just use the ready-made version of opencore 0.8.0 martin lo
way three
leave what the OCLP formed in the efi folder in place, just redesign the folders, as in post # 1-
in EfI folder make new folder "BOOT"

move file boot.efi (you can find it in system>library>core services>) to BOOT folder

this is exactly how oclp worked for me

 

[sebo2001]

^Are you using a (Metal?) GPU that was provided officially by Apple, or one that was retrofitted and that is or used to be able to display a boot menu?

Right now I have Saphire rx580 8GB I upgraded to it in 2018 , during reboot I use to have black screen for a moment then I was presented with boot menu (mojave and mojave recovery) I only had one operating system, this is no longer showing.

I still do have my very old card that came with my mac pro.

I have access to my daughter's laptop with BigSur no other mac with Mojave. I didn't realize OCLP doesn't support it. I still have access to open core 0.6.7 and all the files I used to create my boot menu in the past. I also have carbon copy clone of my drive before I did this. but I think my Saphire RX580 doesn't support native boot, I have oryginal card in storage, but that card when conencted will not work under mojave.

Good. Do you have a SATA to USB adapter for your SSD?

This could still work to get your Mojave drive blessed natively, though.

This is so helpfull, I still have oryginal OpenCore 0.6.7 files I use to create my boot menu few years back,
I think I used Martin Lo 0.6.7 version when I looked at new version my old readme files are from the same source. Sorry I was confused by all the versions.

if I follow the same process I should bring this back to life? Since it was long time ago it will requre some digging, or installing as you suggested version 0.8.4 would work with Mojave as well?

Can I do this on laptop with BigSur with USB to SSD dongle?

I really apreaciate your respense it gives me some help, but I realy want to have full picture before I will mess this even further.(

 

[sebo2001]

This could still work to get your Mojave drive blessed natively, though.

Yes I have the usd to SSD adapter.

How can I bless the drive, right now recovery mode doesn't work, all I see is black screen. When pressing Option key it stays at black creen, and when Command R I see grey crossed circle and computer shutdown.

connect via usb with your daughter's computer, (bigsur will see the disk),
then run the cloverconfigurator from the martin's config,
find "mount efi" menu
mount external disk with EFI
when the clover executes the command
find and open in finder efi disk
NOW you can erase everything inside efi>efi (except windows folder)
copy two folders from martin (better version 0.8.0- with this version you can upgrade to bigsur- but you should edit config as in martin's video ) BOOT and OC
insert this ssd in macpro- it should work as usual

OCLP has different folder tree
folders need to be organized, as it is done in opencore
I know this for sure, I recomposed them and everything worked
use any method I described
all three methods worked for me

I'm gonna give this a try when she comes back form school, this would be amaizing if it works!!

the opencore was already blessed,
opencore can't find file boot.efi
you need to create a "BOOT" folder in EFI/EFI folder and transfer the boot.efi file from the system folder to it

and don't experiment anymore with opencore automatic configurators (like OCLP)
- do as in post#1 or use martin's version

Perfect. So the way this works is that you would remove the SSD from your Mac Pro, connect it to your daughter's laptop, access the EFI partition on your SSD, delete the files, reinsert the SDD in your Mac Pro, and boot into Mojave natively (because at this point, Mojave will be the only bootable item).

You can't with your current card, but if you use your original card, then you should be able to bring up the boot picker by holding Option and bless your Mojave disk by holding Control and pressing Enter. You don't actually need to complete the boot process: the blessing should still take effect.

OLCP made this tree:
EFI>
EFI +SYSTEM
in EFI>OC (the standard folder as OC 0.8.0 with many kexts and drivers and with working config file)
in SYSTEM>LIBRARY>CoreServices>Boot.efi
because the installation procedure did not complete correctly, then the OC does not find the boot.efi file
he need to move boot.efi in new folder BOOT

You guys are absolutely amazing! Thank you for all the help. My daughter finally let me use her laptop. And drive is back 100%,
I connected the busted drive via USB to SSD dongle, and downloaded the Martin Lo package 0.8.0 to get Clover Configurator. Mounted EFI partition, deleted OC and BOOT folders, boot was probably ok because it was with old date and boot file was in it also with old date, but OC had freshly modified dates and different structure, I have found my old 0.6.7 version of Martin Lo and replaced both folders with it. Drive boots and show a boot picker, I'm back in business

I cloned the drive to some spare SSD and now have native Mojave to play with on the new drive. CCC doesn't clone the EFI partition. Old drive upgraded to the newest 0.8.0 version on Martin Lo

My Video card doesn't show me native boot menu, only Open Core. I have placed a blank SSD and USB with OCLP and I would not see boot selection when holding the Option key, just black screen (I did NVRAM reset)

Would this work whe nupgrading to BigSur:
If I want to upgrade to BigSur clean install or if impossible upgrade. I create bootable install USB disk with BigSur and OpenCore boot menu, so when I boot Mac I see main drive boot menu first and then USB disk menu with BigSur Installer I select BigSur Installer while holding Option key so when I format main disk this option would be selected. I'm trying to avoid using my old Apple video card just for installation. Is there any easier way? In place upgrade is it done by clicking on big sur Installer in Application folder?


Again BIG thanks to all the legends who helped out and made suggestion.

Again BIG thanks to all the legends who helped out and made suggestion.

you will not be able to install BigSur without additional effort,
before installing BigSur you need to make changes to the config
1.if you are using the opencore installation method, as described by cdf in post #1, then you should read the paragraph
"macos"
Recommended update options:

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

2. if you are using Martin's version check "additional option 3"

Activate AMD hardware acceleration

I created a new "easy to install package" as per many requested (based on the official OpenCore). [The attached package updated to 0.7.9] For those who only need HWAccel, post #594 has everything you need. This new package mainly offer HWAccel + boot screen. Also, this package should work in...
