there's a button to click to download the installer to create the USB or install directly, from within the patcher. That doesn't work

Quick Time video and Youtube video works ?
What are the kexts that you have installed exactly for this Graphics card ?
Can you make us a video screen of your macOS Catalina
Can you send some screenshots with the dock showing on different backgrounds? The easiest test I've found is to open iMovie. It will instantly complain if you don't have acceleration loaded properly. Can you open iMovie and see what it says?
I did not test iMovie because iMovie sucks on this machine even if it is executed under Sierra High.
Unfortunately I cannot continue further tests because because of Mylio not working I had to switch back to Sierra High. Too sad.
I once tried Mojave on this machine and this was true unusable. Wrong colors and a lot of issues.
Now at least these problems have been resolved. The "only" this missing seems to be graphic acceleration.

I did not install any kexts explicitly. I just took the SSD working in a MacBook 5.3 and booted from this SSD.
Youtube videos are working. Also video stored in Fotos (760 p) were playing fine.
Main showstopper for me was Mylio which made me switch back to Sierra high.
No miracles here then, as expected.
This ended up being my problem
With 2 graphics cards, the installation died out at ~90% on the gray screen.
the simple answer is to remove the original card for install (I've yet to try to re-install it for general usage)
Some things I learned along the way, not sure if it's my problem specifically or what...
*I wasn't able to download the Catalina installer using my vanilla El Capitan and the catalina patcher tool - I had to use a separate computer / virtual machine to grab the installer.
*I wasn't able to select the USB drive created by the patcher tool as a bootable drive with the apple preferences boot selector, this meant that without a flashed video card I couldn't select properly which drive to use on boot up. I needed to do "install to this machine"
In the end it is working. I get metal support with my GTX 780. All seems well.
Just a lot of stupid mistakes that I did where I made it much more difficult than it should have been.
Thanks all for your help!!
Question to people with more knowlege than me:
I updated my Mac Pro to Catalina (via Macbook Pro) and put the SSD-drive back into my Mac Pro 2009 (5,1 with Bootrom 140.0.0.0)
The Mac Pro runs Catalina perfectly in every way (SIP, Graphics, Audio, iCloud, Airdrop, Pro Apps and all that stuff).
So, what exactly is the dosdude1 Catalina Patcher for?
Only for direct installation on the Mac Pro?
Why all this Post Install stuff?
I'm kind of confused...

Confused? There are multiple ways to install Catalina. You happened to find one.
If you did a direct install or update from a previous macOS, you could use this awesome patcher as I did. If your MacPro5,1 has a legacy NVidia graphics card, then you'd use "Post Install stuff" to apply the legacy graphics patch (NVidia Legacy Graphics are no longer natively supported after High Sierra).
Thank you deeveedee
My confusion just stems from the automatically suggested post install fixes for MP 5,1, like the audio patch for example which is not necessary.
Just to be clear, the legacy graphics patch does not fix Metal-supported nVidia cards post-High Sierra. Rather, it enables acceleration on non-Metal cards, which were dropped in Mojave.
macOS 10.15.3 Dev Beta 2 is out and successfully installed using the pinarek,jackluke method patches holding steady
First, let me say that the DosDude patcher is AWESOME! It extended the life of my Legacy NVidia Card while I waited for AMD graphics card prices to drop (which is why I donated and you should, too).
I just ordered a Sapphire Pulse RX580 for my MacPro5,1 which I have dosdude-patched to enable support for my Legacy NVidia graphics card. Since I'd like to be prepared for a painless installation of the new AMD graphics card, do I need to remove the applied legacy graphics patch prior to installing the RX580? If so, can I simply remove GeForceTesla.kext and NDRVShim.kext from /S/L/E (and rebuild kextcache)? Any other dosdude-patching that I need to undo before installing the RX580?
Thank you and thanks again to all who made the DosDude patchers possible. You are amazing.

Mac Pro can run Catalina almost natively. Just need an argument in the Vram.
hello..
can you tell me how you did that, the installer i have only shows the 10.15.2 to install??

True for booting and running... Installing and updating is another matter however... Luckily we have multiple ways around that too...
My update from DP1 to DP2 for Catalina 10.15.3 was without any errors or problems.
EVERYTHING runs like a supported MacBook.
EVERYTHING runs like a supported MacBook.
are you using the software update pref Panel for the updates??
1 Run this script from the terminal
2. After the update is done downloading run this script in the terminal before clicking restart it does take a while
Unfortunately, the legacy graphics patch modifies some core system files (including GPUSupport, OpenGL, CoreDisplay, SkyLight, and IOSurface) so a Metal-supported card will most likely not work anymore. You should perform a fresh install of Catalina over your existing copy. You won't lose any files.
I ran the script :
Finding available software
No new software available.
now what, I'm still at 10.15.2??
