Hi! Any news enabling HW accel on Vega cards (Radeon VII) for Ventura+? With RX580 everything is working as expected, but not with Radeon VII.
Got a tip for us?

MP 1,1-5,1 Activate AMD hardware acceleration

I just got a 6800xt and installed Monterey with OCLP on a fresh install. OCLP says that there's no post install patches, but HW acceleration didn't seem to be enabled. So I replaced OC from the OCLP install with the OC from post 1314 and VideoProc now says HW acceleration is enabled. I want to test it though, and not really sure of a good way to do it or good videos to use.
Post 1314 also says it'll let you run 32 bit programs, does that mean I can run my Steam games like HL2 and Portal 2?

Hello
I have 2 questions
one is when is this new version of opnecore expected?
version 1.0.3 has already been released.
My other question is whether the compatibility with rx 6600 xt video cards on Monterey+ systems has still not been resolved?
Thanks
Regards Krisztián
Hello! I’ve learned a lot from reading this forum! However, I now have a dilemma. I have opencore running on a Mac Pro 5,1 with the newest version of Sonoma. I did all this after I installed a new Radeon RX 580 graphics card in the Mac Pro. I run a professional recording studio and actually did all this on my back up Mac Pro first. I have Mojave on a separate SSD and Mountain Lion on a separate SSD also for some older software I use for some of my work. However, when I select either of them from the boot picker, I get the prohibited symbol that I guess says I have no operating system? It’s a circle with a cross hash through it! Totally desperate now and will pay for a consult. Please help!
This OpenCore recipe spoofs 2019 Mac Pro or iMac Pro to run unsupported macOS releases, so you are limited to run the exact same macOS releases that 2019 Mac Pro or iMac Pro runs:
- 2019 Mac Pro starts with 10.15.2.
- iMac Pro starts with 10.13.2.
So, you will never run Mojave/Montain Lion spoofing 2019 Mac Pro or never run Mountain Lion with iMac Pro spoofing.
For running Mojave/Mountain Lion, bypass OpenCore completely via Apple native BootPicker. If your GPU does not support Apple native BootPicker, you will need EnableGop or flashed GPU or BootROM reconstruction service.
Thanks so much for the reply! I just walked back into my studio. Do you mind walking me through what I should do?
This thread explains the issue in detail:
You won't boot Mountain Lion WITHOUT bypassing OpenCore, but if you change the board_id from 2019 Mac Pro to iMac Pro you can boot Mojave, this will require opening the OC config.plist located inside the ESP and change the board_id from 2019 Mac Pro to iMac Pro.
To run Mountain Lion, your only way is bypassing OpenCore completely, via flashed GPU or EnableGop/BootROM reconstruction.
Btw, a friendely reminder that this thread is not for OCLP support, you are using OCLP to run Sonoma and this thread is not the one for getting the help you want.
Also, if you mean using “Startup Disk” that gives me the prohibited 🚫 symbol too
Apple NATIVE Boot Picker, not OC/OCLP Boot Picker, two different things and once OC/OCLP is loaded the 2019 Mac Pro/iMac Pro is spoofed and will be limited to what it can run, see the thread I've linked to learn how to see how to differentiate one from the other.
Plaes read the thread that I've linked, you are asking questions already answered there, I'm not going to repeat myself once more here…
There are many ways to arrange your setup to boot into new unsupported version of Mac OS while also being able to boot into older versions.
I run 10.4 Tiger to 15.x Sequoia. Every single one of these can be booted via OpenCore.
I tend to use RefindPlus to boot the older ones (equivalent to Native Boot) but definitely doable via OpenCore.
Below are screenshots from Tiger and from Mountain Lion booted via OpenCore (iMacPro1,1 Spoof).
First thing to try is:
- Open your Opencore config file, config.plist, with something like TextEdit on your Mac
- Look for
<key>boot-args</key> - On the next line, starting with
<string>, add-no_compat_checkto whatever is there - That is, change to:
<string>OriginalItem_1 OriginalItem_2 ... OriginalItem_n -no_compat_check</string> - If currently empty, you will have:
<string>-no_compat_check</string>
As mentioned though, there are multiple approaches with each approach having pros and cons.

I’m not sure. But what @tsialex said and did with my Boot ROM Reconstruction and Enable GOP, I can boot into, Sonoma via OpenCore, Mojave via Apple Boot, and Mountain Lion via Apple Boot. I only use the OpenCore Bootpicker to boot Sonoma. His process was extremely easy. Basically reset my Mac Pro 5,1 like a brand new 2012 5,1. I’m using a new XVX AMD Radeon RX580 GTS with 3 displays. However I only have one display that functions in Mountain Lion. I purchased a NVIDIA GTX680 on eBay because Alex said this will give me multi display capability because it being a Mac compatible GPU
Thanks for the correction @tsialex! Appreciate you!!read Mountain Lion compatible GPU instead of Mac compatible GPU
You can boot older versions on Mac OS with OpenCore if the
-no_compat_check boot-arg is present. As I posted earlier, you can even go as far back as 10.4 Tiger (at least on MP31). Perhaps Martin's setup has this boot-arg in place. I use a different setup myself.However, the poster is not using Martin's setup and posted to the wrong thread as they referred to setting OpenCore up for Sonoma, which implies an OCLP configured setup. These do not include that boot-arg and needs editing the config file to add it, as a minimum, if desired.
A viable and popular alternative is to apply the EnableGOP hack to the GPU or MacPro firmware or to hire an expert to do it for you; which the poster seems to have gone for and appears happy with.
Hello everybody,
I succeeded in switching RX580 to flashed RX6600 in my MP5.1. VideoProc says HW acceleration is enabled.
Geekbench6.4.0 shows for:
- CPU X5680 SC 590 MC 2774
- RX580, OpenCL 38920 and Metal 37108
- RX6600, OpenCL 53026 and Metal 90939
Are the scores ok?
but improvement results with DxOPL7/RX6600 using DeepPRIME XD/Export RAW-->Tiff are not so good:
- for DC-S1R:
- RX580 1mn 46s
- RX6600 1mn 30s
- for DC-S1:
- RX580 52s
- RX 6600 43s
When I use plug-ins on Photoshop, the analysis is much faster from 45s (RX580) to 30s (RX6600). I timed the Topaz GigaPixel8 to enlarge a DC-S1 TIFF 3808x5712 pixel file to 4724x7086 for 40x60cm prints at 300dpi and the improvements are dramatic:
- with RX580:
- High fidelity analysis 69 sec
- Export tiff 5 mn 25 sec 130 Mo—>164 Mo
- with RX6600:
- High fidelity analysis 34 sec
- Export tiff 2 mn 44 sec 130 Mo—>164 Mo
I've noticed two things: the fans are much quieter, the CPU is less stressed. When processing DeepPRIME XD/Export RAW-->Tiff, I think the process uses the RX6600 more than the RX580 and the CPU less! Obviously, less power is supplied but I can't see the temperature of my (RX6600) GPU card any more with TG PRO.
I tried the MacBook Pro M1Pro 16Gb RAM of my son. With DxOPL8 using DeepPRIME XD/XD2S with Export RAW DC-S1 files-->Tiff, the results are much better: 15s only (RX580=52s, RX6600=43s).
Is there anything that can be done to improve the results? Does anyone have similar results with the same RX6600 card? A comparison with a RX6800 (non-XT)?
Best regards.

Yeah, the only reason I haven’t moved from Mountain Lion 10.8.5 is because I have a total of 84 channels of hardware inserts via 10pcs of HD 192’s on TDM that I use for tracking and mixing. The flip was for me to spend $7k on a new Mac Pro, 5pcs of HDX 16 IO’s at about $4k each and two new HDX cards at approximately $5k each. 7k+20k+10k=$37k for what Vintage King Techs told me that it would probably be a 3% improvement over my current setup! I’m using a Lynx Hilo for my mastering work which I run in Mojave! Going to Sonoma and Sequoia will keep me current on that side of things. And, I only have about 8 plugins that I use now. Hey, Pro Tools is my tape machine and with a high end front end and not hitting it hard brings great results.
Gotcha, I'm in somewhat in the same boat, but a way smaller boat. I just can't justify the spending all that cash for getting the same results, well at least my ears can't tell. I'm still rolling with my DIGI003 Black Lion tweak Mod after two decades, and to be able to track 18 inputs at 32buffer / 48K is still crazy for an old dinosaur, but gets the job done.
I have a top engineer buddy here in Tempe that is still rolling on his 2008 Mac Pro, and has been nominated for a Grammy as well.
I'll never forget reading an article where George Michael said it doesn't matter what it was recorded on, whether a cheap four track like La Bomba, Richie Valens or quad 8. What matters if the song has the mojo to get you on the dance floor.
Yeah that 18-db is the sweet spot, and I also feel it gets the feel just right.
I'm no pro, just like recording my friends bands, and tinker my ideas when something hits my head. Ex 80's rush tribute band bass player. god I haven't played in over 37 years, but I do tinker.
Something I slapped together after I chopped up a drum loop to my liking. ( DISCLAIMER ). NOT A GUITAR PLAYER.
But I can get something meaningful / LOL
What plugins are you using now. I find myself gravitating to only a few. Man some many plugins.

Nice track and I appreciate your reply and what you’re doing with your music! As far as 3rd party plugins go I use:
*Fabfilter Pro L2 (my final mastering limiter)
* Fabfilter Pro MB
* Soothe2
* RESO
* Sonarworks Reference ID
* Klanghelm Deluxe meters
* Standard Clip
* dpMeter4 by TBProAudio
* ABLM2 TBProAudio
* M7 Control (To control my Bricasti)
* Exponential Audio R2 Reverb
Hey Dayo,
I just reread you reply in detail! I can boot into Mountain Lion via Apple’s native Startup Manager by holding down the Option key on power up. The problem is that I’ve lost my multi display capability
