I've got Opencore 0.59 booting successfully on my MP 5,1 with a flashed 7950, however I'm not getting the boot picker when I'm plugged into my Dell U2717 (Tried HDMI and DP) It will boot into Catalina successfully after waiting fine though and everything else seems OK.
Strange thing is that I do get it when plugged into my Dell U2414 via the same HDMI cable, any ideas?

7950 Mac EFI UGA does not support 1440p 60Hz, over the HDMI. You should use Display Port. And make sure the monitor set to DP 1.1, not anything above.
The U2717 has identical resolution as the 27” Apple Cinema Display. The 7950 sure can display boot screen if you do everything right.
A huge thank you to those who set up Opencore.
Yesterday, I finally took the plunge and tried the installation (basic) and it worked first time. Brilliant!
The instructions seemed a bit scary, but in retrospect they're only a few steps.
Wifi has gone (I'm guessing it's the issue with the old Broadcom airport card, but that's not a serious problem: I can either get an updated card, or connect to the network box with a cable).
During boot there are some momentary (?1 second) curious thin horizontal stripes appearing on the top 1/3 of a blank light grey screen. I'll take a pic next time.
I'll probably drop back to 10.14 until I decide about the wifi. But in the meanwhile I have a working 10.15 ssd for my cmP 5,1 ! Thanks again.

Awesome work, that worked perfectly, thanks for all your work on this project as well!
So funny this one yup...
Here is a pic that I have taken yesterday or so with the Memory Tab half way functioning under Catalina 10.15.5 (101)
With the MemoryFix.kext the notification is gone and ram show green and orange ( I do not know how to get green on the top 4 ) opencore-version DBG-060-2020-06-29 I do not think I am getting the green ones with 0.5.9 though.
Could it be possible you think to duplicate somehow the 4 ( green marks ) to get the top 4 showing the same? I mean if the system sees it that way maybe we can get the top showing green as well...
It would be so nice to see green everywhere... I do not know how the system calculate how the ram displays but when I run the terminal cmd I get all the memory seen by the system.
Here with macOS Big Sur ( MemoryNotification.kext loaded in the extension not OC kext folder with 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102
pencore-version DBG-060-2020-06-29But as you can see not doing any effects on.
Y'all have an happy 4th of July
Try this method: https://forums.macrumors.com/thread...unsupported-macs-thread.2242172/post-28640224
it should work.
Do you know how can boot back in recovery with Big Sir? I do not understand why I was able to boot before with the 0.6 and now I am not anymore..
From opencore menu press space bar to show macOS Recovery, and when you select a macOS Recovery, in case of BigSur it's "10.16 BaseSystem (dmg)" or "Recovery Beta", you have to wait many minutes for Recovery to load, more than 5 minutes .
And you should check in your OpenCore config.plist this:
Code:
<key>7C436110-AB2A-4BBB-A880-FE41995C9F82</key>
<dict>
<key>boot-args</key>
<string>-no_compat_check</string>
<key>csr-active-config</key>
<data>
dwgAAA==
</data>
in the delete or block part
<key>boot-args</key>
<string></string>Gotcha thank you so much.. my gosh 5 minutes... That's the price to go in recovery lol..

So this value does not work? -> /w8AAA==
They don't work on opencore, they just disable SIP or standard csrutil, but not the new csrutil, try my method of "csrutil2" from an USB macOS Installer root , it should work to disable "authenticated-root" even without BigSur Recovery.
Got some free time so getting round to installing OpenCore. At present am running Mojave off an NVMe SSD. The instructions on the first page suggest I would need to pop in a spare SATA drive, install Mojave to that, boot into Mojave on the SATA drive, then wipe the NVMe drive to install OC and Catalina. A few questions:
- Is Catalina recommended at this point vs Mojave? I recognise this is a subjective question, but are there any compelling reasons to use it in the context of OC? I don't feel strongly either way otherwise.
- If it's a toss up, I might stick with Mojave. Is it possible to install OC without doing a complete wipe of the drive?
- Is it advisable to keep Mojave around as a fall-back, in case of OC issues?
- I've got Boot Camp installed in Legacy mode, so it doesn't hose my NVRAM. I understand that OC's boot picker can only see Windows in EFI mode (and has NVRAM protection that makes using EFI OK). Is it possible to just convert Windows to EFI without a reinstall? If so, what's the easiest way? Winclone 8 appears to be able to do this.

Thanks for the tip on this after some searching of this thread I found this about the ebay bought or 3rd party bought used cards mining versus GOP rom. I just found it hard to believe that all the GPU cards I tried would not get me to the OC GUI Picker screen until I grabbed my Sapphire RX580 (bought new) from my Z380 MacOS clone installed into the MacPro5,1 and it immediately went to the GUI picker.
Cards I tried none would work EVGA GT 640, 710, 740, AMD Aero RX 560 both 4GB and one 2GB. I have not tried any of my EVGA GTX 770's (most used) which all work natively in MacOS.
I have to install windows on my Asus Z380 and go to Techpowerup and find factory ROMs. Does Techpowerup offer Nvidia factory ROMS and a tool to flash the Nvidia cards I listed?
Also thanks for attaching your OC a ways back this is the one I am using now with these boot-args listed below but should it be the same for the RX 560 and Nvidia cards I listed above?
agdpmod=pikera shikigva=80 mbasd=1 -wegtree -no_compat_check no32exec=0
Most older cards doesn't shipped with UEFI GOP ROM. You may contact the manufacture to ask for a GOP ROM. Or you may google how to make a GOP ROM for your own cards.
For OpenCore with Nvidia cards, you don't need board ID spoofing, also don't need agdpmod=pikera shikigva=80 -wegtree. All these are for HWAccel, which not avail for Nvidia GPU in macOS.
mbasd=1 is to make Apple USB SuperDrive to work on cMP. You can remove that if you don't need it (this boot argument has no adverse effect anyway)
For those who test my "csrutil2" method to disable the new BigSur SIP that is
Base64:
hex:
csrutil authenticated-root ("csrutil2" is mainly for non-APFS Mac or legacy usb Mac), because recent IOUSB Mac can boot either the USB BigSur Installer or its Recovery with responsive input output devices (mouse, keyboard and so on), I noticed that for opencore nvram csr-active-config this should be the right value:Base64:
dwkAAA==hex:
77090000
Speaking of it, I guess for me it does not work I do not know but see the attached; Booted from Mojave USB installer

Never mind I did not read correctly but it has to be renamed Ohhh gosh ...! Even renaming it will not work....Speaking of it, I guess for me it does not work I do not know but see the attached; Booted from Mojave USB installer

I guess then you should use an USB Catalina Installer, because csrutil2 requires more recent SDK .
Actually quite straight forward. Type a command into terminal, press enter, go to make a cup of tea and by the time you get back, you have OpenCore built.
Only catch is that you need to have Apple's Development Tools installed which I can appreciate that some might find daunting.
The installer is made with apple "createinstallmedia" method ? Because this method requires a booting with BaseSystem.dmg Ramdisk.
Anyway you could copy the file on any USB device, then boot from a Catalina Recovery, maybe make an external Recovery with this: https://github.com/chris1111/Catalina-Recovery-HD-Partition
and from there open terminal:
Code:
cd /Volumes/ ; ls
cd YourUSBLabel
./csrutil2 authenticated-root disableAlso here is what I obtain when I try to boot from Big Sur Recovery under 0.6. The attached pic is not clear and so sorry about that that thing appears in a blink of an eye very hard to capture even with slow mo so imagine how fast that goes... Anyways.
Hope that can help to determine why we are not able to boot from the recovery Big Sur.

Guys OpenCore have lost the boot picker, for some unknown reason, it was working since yesterday i was attempting to install Big Sur!
After the first boot into Big Sur usb, no more boot picker, it’s loading Mojave and Big Sur but doesn’t show anymore the picker!
But for unknown reason it shows with R9 280X and no more for RX 580 Pulse 8Gb, i don’t know why.
Any advice?

Thanks for the reply. I checked both ITX Aero RX560's 4GB and they are stock rom UEFI yet I can't get to the OC Canopy GUI Picker just a black screen then boots to desktop.
