Hey there,

Just to confirm our issues are the same:

- power on and black screen for 10 seconds
then screen shows a box that’s usually off white or light yellow, sometimes pink
- then I got boot picker screen (I think that’s the term, where I get to choose Mojave or Catalina login And the disk icons are multi coloured ..... but crazy like your staring at the pixels of an old crt television.
then the Apple logo with boot up progress bar but the Apple logo is one crazy color like hard pink on a dark blue background
- then the nice black loading screen with the white Apple logo kicks in

is that what you see?

This is exactly the same ! I tried all sort of things and it doesn't work...

ohhh one other thing and this will further show my ignorance but if the rx580 is set to gaming mode what would I be switching it too and will that draw more power?

i never did the Pixlas mod, so I have the usual power draw from the 2 6 pin and the pcie slot, will this switch draw more / too much power?

that would be awesome 👍🏼

FWIW I took a look at my 580 and there was no physical switch To change from gaming mode (this was advice received a few posts back) there was a CD that I assume allows you to switch from gaming to Overclocking but I am not sure if it will work on a Mac and even if it does not sure I want to switch it to Overclock considering my power draw concerns.

Too bad there is no switch - it was a super easy fix for me. I am not an RX580 expert, mine is an XFX version and a tiny switch is right near the 2 6-pin connectors. I see that many other RX580 have a switch but others seem only to refer to software for changing settings. On the CD there should be a manual. I am sure you looked through that already for any mention of a hardware switch setting. I do not think you will draw too much power (maybe less) by switching. I don't seem to have any power issues.
You might be able to boot to windows to run the software.

I also have all these odd color problems when starting up with open boot picker. My XFX 580 has the small switch, but it doesn't change anything in the 2 positions.

There seems to be confusion here. The regular off the shelf AMD Metal card is supposed to show OC boot picker. Flashed AMD card will show Apple genuine boot picker and the OC boot picker.

Use the Driver#### and DriverOrder boot variables to load a UGA on GOP driver for the AMD card before the Apple boot picker loads?

Mac Pro 3,1 NVMe support + Upgrade Guide + Questions

Adding NVMe and apfs support to MacPro3,1 without flashing ROM or using a EFI boot loader or Shell: You can place the EFI drivers on a EFI or FAT or HFS+ partition, then set Driver#### and DriverOrder NVRAM variables using the commands discussed here. In my example below, I chose a folder...

Needs details from @joevt as to the specifics for this potential application.
 
For anyone who is interested, I followed up on the OP's suggestion to use EFIClone to make the changes to the EFI partition when you are cloning a boot drive for Catalina. I tried to get it to work with the SuperDuper! at least a half dozen times. The cloning went perfectly, but it bombed out when it went to run the script for the EFI. I did find I could just add it manually after the cloning, but it does require a lot of extra work. I inquired about the problem at Shirt Pocket Software, and they said it was the script. I also tried CCC as they have a new version with a 30 day free trial. EFIClone worked perfectly the first time and subsequently. I have always had good luck with SuperDuper since I plunked down my $28 a decade ago. I originally learned to clone Macs with CCC, but prefer SD. Has anyone had success with EFIClone and SuperDuper?

Really? How is that? Copy the entire EFI folder and paste it to the ESP partition of the new drive is complicated?

Thanks star, I didn't think your suggestion would work, after I did that once, and the OC EFI didn't boot. I guess I just did something else wrong??? While I think having a one stop clone would suit my purposes better, I will definitely use your suggestion to just copy what belongs in the OC partition (EFI). On the other had, I can now get through the Basic (Part1) commands without a reference. Live and learn... Thanks for the help.

You may want to reveal hidden files before copy to select any disk label (if existing) other than that it is pretty straight forward.

So I'm getting mixed results using open core 0.61, no boot picker from DVI on an old apple studio display (sapphire pulse 580 8gb)
But I can see the bootpicker via hdmi on the TV

and unknown processor (mac pro 2009 flashed to 2012 model running 3.33 GHz 6-Core Intel Xeon

This is what I have been warning all along in respect to the spoofing MLB, serial numbers, UUID etc.
Now you may have to call Apple. I would still try to delete that computer from iCloud.
Here are troubleshooting steps:

First thing try spoofing only the board-id and nothing else!

Could you elaborate on this a little? If you follow post #1 are you at the same risk? When is it essential that you log out of your apple id? There are bits and pieces in this thread but it would be great if it was put in one place. If it is an essential thing perhaps it could be added to post #1 @cdf

There is nothing in post one suggesting using serial numbers other than the one in the smbios. The only spoofing mentioned there is the board-id spoofing, which is perfectly safe.

Someone on other thread wrote that OTA updated from beta 9 to beta 10 through VMM spoofing, I guess instead only requirement is a supported Mac board-id spoofing, for BigSur VMM spoofing is unuseful, I mean apple is not delivering OTA updates to virtual machines, mainly because of the new tricky snapshot booting Update Volume, the check is only on the board-id .
Code: 
diskutil mount Update
open /System/Volumes/Update/

I don't think you are right. Using Software Update, I upgraded a Catalina VMware Fusion virtual machine that is enrolled in the beta program to Big Sur beta 9, so I'm pretty sure Apple is indeed delivering OTA updates to virtual machines. I didn't look for the update. It was offered to me!
 
Okay - I've gotten OpenCore 0.6.2 installed with Catalina 10.15.7 - I'm using a non-flashed R7 270X which works great once you get into the desktop - but I'm not getting any output until I get to the login, just like my previous installs without OpenCore. I wait about a minute and eventually the login window comes up.

FYI - If I swap in one of the original Radeon 4870 cards everything is visible as soon as the machine chimes. As soon as I put in the non-flashed card and boot I get nothing until desktop.

I'm running:
Mac Pro 4,1->5,1 with BootROM 144.0.0.0.0
original Dual Quad Xeon
16 GB RAM
Non-flashed R7 270X

Any help would be appreciated. I've got 9 of these I'd like to get running with Bootpickers working properly for work - I just can't seem to get anything showing for the Bootpicker portion.

Thanks for the help!

Updated from Beta 2 to Beta 10 through System Preferences -> Software Update with nothing except iMac Hybridization (no vmm flag). ~8GB download, couple of reboots but worked fine. Video Proc reports hardware acceleration is good to go.

So, I just updated to OpenCore everything works amazing on Catalina, but the only issue that I found is that I am having problems with my Bluetooth 4.0 that I got a couple of months back and was working great in Mojave. Anyone has any experience with this?

EDIT: After some playing around with the Bluetooth card it works now. Perhaps it wasn't placed well in the socket or it was a software thing after the computer going to sleep.

If you've hidden the boot picker, accessing it is easy: Press and hold the Escape (Esc) key immediately after turning on or restarting your Mac. Release the key once the boot picker appears.

Hi,

that doesn't behave like this with my Mac Pro 5,1. If I hold the Esc key the screen stays black.
I figured out that when the cursor shows up I can release the key and then suddenly the boot picker shows up.

Is it a bug or is it only my machine?

Thank you.

That's the way it functions with mine. Some say you can use the option key as normal, but that never worked for me.
