Our friends in Cupertino have broken support for EFI 5700 in 10.15.5.
Stay on 10.15.4 until we get a fix. If your 5700 has a ROM switch and you are on 10.15.5, you can use the PC side to work around for now.
Will update as we find solution.

Looking forward to a fix ASAP...

Is there a 10.15.6 fix for the 5700XT?
8/15/2020 02:54:13 am
The 'Netkas fix' worked again for me... I applied it to my cMP5.1 with an MVC 5700XT after upgrading to 10.15.6.
9/24/2020 09:05:08 pm
Can someone verify the new update 10.15.7 fixed the issue?
10/6/2020 11:01:08 am
I did the update 10.15.7. This did not fix the issue, I spent a lot of money so I could have the boot screen.
10/12/2020 02:10:14 pm
10.15.7 still needs our patch to work:
7/28/2020 10:07:10 am
My order was completed and sent within 4 days of payment. (took another 10 days for the card to make its way through the postal service lol). The card, so far, is working great!

Are you still working on a fix for 5700xt 10.15.5?
8/22/2020 12:23:30 pm
Yes, we are still working on a fix. Patch is also now shortened. You just type one command in safe mode, reboot and all is working again.
8/22/2020 02:33:06 pm
Ok, what is the command? I have a macvid cards 5700xt and I'm running 10.15.6. Installing the card in my 2010 5.1 is a no go with kernel panics.

curl -qLs https://pics.macvidcards.eu/fix5700.sh > fix5700.sh; sudo sh fix5700.sh; rm fix5700.sh
10/6/2020 11:32:04 am
So I did this, but my cMP keep booting into safe mode. Is there a way to fix this?

Upgrade from 10.15.6 to 10.15.7 went smooth. Our patch is still working just in case:
9/27/2020 06:28:37 pm
Reinstalled the MacVidCards 5700xt in my MacPro 5.1 and tried your patch today. It worked smoothly without a lot complicated steps in terminal. Running 10.15.6. Geekbench compute score is 66672. Much improved over the RX580 (41557) I took out. Scrubbing 4k video is much smoother with many fewer dropped frames. Big thank you to MacVidCards Europe for the patch.
Hello how do I go from 10.15.4 to 10.15.7
9/30/2020 08:58:42 pm
I'm using a 5,1 (2012) and wondering how do I go from 10.15.4 to 10.15.7
I figured it out...
10/1/2020 12:00:15 am

Is California alive?
12/6/2020 12:24:38 am
HI, I ran the update then highlights and folders went orange and the color system is totally out of wack. The Macos Catalina Patcher came up with a message to run a patch for Nightshift which I did. Do you have any sugesstions?
10/1/2020 09:07:21 am
macOS 10.15.7 works great again with our patch.
10/1/2020 01:01:15 pm
Update worked but it doesn’t see my 5700xt in a Mac Pro 2012 5,1 the default post install items didn’t work?
10/1/2020 01:10:21 pm
All works well.
10/1/2020 08:59:17 pm
Where can I get your patch? Looks like 10.15.7 is working it just doesn't show the cards name, just says 8GB graphics card...
10/2/2020 02:21:08 am
Use this - all works perfectly:
10/2/2020 09:46:16 pm
Got It! Worked! Thx!
12/2/2020 10:16:32 am
How do you install the patch? do you have a link to the install?
10/5/2020 12:13:42 pm
guys just get cards off the sellers on ebay, i've bought a few over the last few months from the boys based in the UK and have had no issues whatsoever. MVC does a great job hacking the cards but customer service sucks.
10/5/2020 04:14:16 pm
See our shop on eBay with 100% positive feedback - same product, best customer service: https://www.ebay.com/usr/macvidcards-europe
10/12/2020 01:10:28 pm
This is MacVidCards USA, while we are a different company located in Europe. Only product is the same and customer service is way better. All cards are shipped within 24h. Delivery is within 2-7 days. We've never sold any customer card as we note every serial number and model. The US guys are probably affected with COVID-19 hence there is no contact with them.
10/12/2020 02:08:30 pm
It's highly worrying. Sadly, we cannot help you with this matter.

Hey all, I got a APPLE EFI AMD RADEON RX580 8GB... I got it to boot up which is good. BUT its showing only 14 Megs of Ram.... and shows some artifacts. I am wondering if its the Ktext loader I used when trying to get a non flashed RX580 up. Any suggestions of what to try? I did email support but no word back yet. Id like to get the system functioning again. PS. I am running Catalina. Thanks for any tips.
11/18/2020 02:53:15 am
Hello, these cards doesn't require any extra kexts. Just clean installation of Catalina with DosDude patcher and all will work just fine.
11/19/2020 05:42:32 pm
thanks. I ended up doing a fresh install and seems to work now. Must have been something from the Ktext updater or just the first non flashed card I tried. IDK.... but in case anyone else runs into the the problem... my new card showed 14MB VRAM.... ended up doing a clean instal with the DudeDos1 patch and the system seems to be working now. thanks all.

The good news is Big Sur works with out flashed cards out of the box - no extra patches needed.
11/20/2020 03:51:29 am
I mean with our flashed cards ;)
12/29/2020 05:44:05 am
I realize this thread is about the 5700xt, but as of 10.14.7 or so, my Vega 56 (8gb) that I bought new/pre-flashed from you guys stopped showing the boot screen.
12/31/2020 08:54:12 am
Please flip the BIOS dip switch on top of the card.
