Ah, now that I have summarized my config, I think I see the problem. My USB stick needed to be formatted as Journaled HFS+. I'm going to try that and will report back.
Did you guys manage to increase Intel HD 3000 VRAM on macOS Catalina as well?
I have almost the same setup, and had the same problem. If you move the USB stick from the efi card to the usb2 port in the front of the tower, it should show up.
The system cannot boot off devices connected to a third-party USB controller card. Plug the drive into one of the internal USB 2.0 ports, and it will work.
You can read here. Not tried but who knows?...))
Yes, use the method outlined here : https://forums.macrumors.com/thread...unsupported-macs-thread.2121473/post-26343097
Make sure you use : mount -uw / before you begin any commands to allow writing to protected folders in Catalina.

I tried that, with the internal USB ports in the back and in the front, with same result (usb stick not available as startup disk option).
I have now also run the dosdude catalina patcher to create a bootable volume on an external rotating hd, and plugged it into the front and back usb ports, and it also does not show as an option for startup disk.
I notice that I used Disk Utility, in each case, to format disk as Journaled, but after Patcher ran, the disk was HFS+.
Also, the hdd came from an old Windows machine and it still has a Windows NTFS Recovery volume on it.
Could you please post up what you did to get it to work, I've tried a few times with no success.
I did the following
and it still reports as 512mb not 2048mb
I did the following
Code:
sudo mount -uw /
sudo cp -r AppleIntelHD3000Graphics.kext /System/Library/Extensions
sudo cp -r AppleIntelSNBGraphicsFB.kext /System/Library/Extensions
sudo chown -R 0:0 /System/Library/Extensions && sudo chmod -R 755 /System/Library/Extensions
sudo kextcache -i /
sudo rebootand it still reports as 512mb not 2048mb
Check this thread (last post by jackluke):
https://forums.macrumors.com/thread...cs.1766384/page-9?post=28071534#post-28071534
that is what I followed and could not get to work???
not sure if I missed something.
Download the kext files here:
https://forums.macrumors.com/thread...ed-macs-thread.2121473/page-199#post-26343097
Choose the desired VRAM size.
But before replacing the kext files you downloaded, open terminal and paste this line: sudo mount -uw / ; killall Finder
Then, go to System / Library / Extensions and replace both files
After that, go back to terminal and copy this whole line (copy and paste all at once):
sudo chown -R 0:0 /System/Library/Extensions
sudo chmod -R 755 /System/Library/Extensions
sudo kextcache -i /
sudo reboot
Wait until your mac reboot (it may take a while). DONE!!!
It worked for me (MacOS 10.15.2)

Hello,
I have a 27" 2011 iMac with a GTX765M running MacOS High Sierra.
The card was flashed with Nick [D]vB vBios and is giving me a boot screen.
I am trying to get the iMac to run Catalina now.
The iMac bootrom is stuck to 82.0.0.0 and I think it needs to be upgraded but I can't seem to find how.
I've reinstalled completely High Sierra using the latest High Sierra installer and bootrom was not upgraded.
I've tried the OfficialAPFSFWUpdate file from Dosdude website to upgrade the bootrom but I am getting a black screen when I reboot and I am not sure if something is happening so after a while, I have to press the power button to restart it.
I am wondering if I should get an original radeon 6770M to be able to patch the bootrom first or if there is another way. Or maybe I am missing a step and it's not about the boortom.
Right now, I am able to see my APFS drives when holding the option key at boot but once I'll try to boot from one, I'll get the prohibited sign.
Any idea?

Are you trying to install onto the original factory hard drive? I believe some people have reported that installing onto third-party storage devices may block the firmware updates.

That's the problem in a nutshell. It is a niche display interface even for the MacPro's and, on the supported iMacs, quite unlikely to get tested. Add in the fact that Apple addresses bugs according to the frequency that they are reported and you have a situation where it is unlikely to be fixed outside of a hack to drivers.
I'm on 10.15.2 and have tried with my 8,1 a few times with both the 2048 and 1024 followed the instructions to a tee and still no luck still reports as 512.
Any other ideas?
I am using a Samsun SSD so clearly not an original drive.
Thanks for the tip, I'll try again with an Apple original drive.
I got it to work by running the patcher and re installing all patches after following the instructions above.
not sure why it wouldn't report the ram as 2048 otherwise
Two questions please:
Thanks
- does the installer media modify itself? In other words, can I use it more times or must I recreate it for each computer/disc I update?
- does the first part of the process (OS install) depend in some way on the target computer? For example, does install something different according the video board or do only the post-install patches depend on the hardware?
Thanks
Bootrom update working only.with your original graphic card... I have the same.problem... after install high sierra i must install.my.old amd card to.update the bootrom...after that i install.my.nvidia back and boot to catalina
I have install high sierra on an external hdd drive
I don't know much about how Windows formats storage devices, but it seems to me that if your USB HDD still has a Windows NTFS Recovery volume on it, that you haven't yet "fully formatted" it using Disk Utility, and maybe that's why it's not working for you as a bootable drive on your Mac Pro. Run Disk Utility again, and on the left side of the window, select the icon for the HDD itself (its uppermost icon, not any of its lower icons, which are for existing volumes on the HDD), and erase that--it should (?) remove the Windows Recovery volume. Then install a patched Catalina installer onto it again, and see if that boots.

So it's the original video card that matters and not the original HDD?!
Well I guess it's safer to use both if possible and since I have them I'll do that then.
Thanks!
Probably because the dosdude1 catalina patcher you used copied the Video patch kexts in /Library/Extensions/ rather than /System/Library/Extensions/ , so try to replace my patched kext there and they should work.
Apple apparently has fixed this Wifi connection problem in 10.15.2.
Just tried on a bus which provides open Wifi but still requires an OK in a pop-up window.
I had the problem with 10.15.0 and .1.
Another problem Apple has fixed in 10.15.2 I've mentioned earlier: exporting photos from Photos in sequence now preserves the intended (time-)ordering. Ordering appeared random in 10.15.0 and .1.
Catalina I know meanwhile as a very stable system which does all I need on my MBP5,2.
Mojave may have been a bit quicker on my machine (won't go back to verify) but I appeciate to use the latest macOS.
Thanks dosdude1 and all contributors!

Hello Jowaju, (and Jackluke)
Is there an advantage/improvement to increase VRAM on a MBP 8,2 core i7 16GB RAM (w/ disabled dGPU) with Intel HD Graphics 3000 512 MB switch to 1GB? Not running any games or intensive graphic use apart from sometimes large PShop 2020 files and rare basic video editing? Thanks
