MP All Models Turn a "new" Sapphire RX580 PULSE into the "Mac Edition" card

For me it does not work — VideoProc doesn't detect anything new. 4k HEVC movie playback is still super laggy.
Airplay mirroring still shows only black screen.
It doesn't change anything for me.

I'm using a PN that is one digit off from what you're asking and have ATY,AMD,RadeonFramebuffer natively.
Hey bro, could you please elaborate on how you mod the 'part number'? My Sapphire RX580 8G Nitro+ was also assigned with a generic part number. I'd like to see how you dealt with it. Thanks in advance!

The Orinoco framebuffer is NOT for Nitro+, but it seems you can still do that without any noticeable adverse effect.
Hi Level did you get a working rom? Can you share the modified rom as I have the same card?
Hi Techchallenged1, I made one for my Sapphire RX580 8G Nitro+. You can try it out if you want . Although "Orinoco" framebuffer was assigned, there's no video output until the login page. FYI, I am using this graphics card NOT for a real Mac, but an Intel NUC8 hooked via an eGPU enclosure.

Hey, thanks for your information. It worked just fine. The Orinoco framebuffer has 6 ports however there are only 5 ports on RX580. I tried to find all possible framebuffers in macOS (see attachment dump.txt). None of them matches my layout/ports.
Just get this from Apple
So again, they artificially block 5,1 using GPU video acceleration.
MattyStonie’s screen capture has Intel Power Gadget running, which means, it shouldn’t from a 5,1, but more likely from Hackintosh or eGPU from other Mac.
In this case, everything still as per Apple’s script. Everyone can use video hardware acceleration except genuine classic Mac Pro users.
But the good news is that we know the function is there, just how to activate them.

Maybe overwrite the kext with the 10.14.0 version? The blockage must be inside the kext. The info related to the cMP same as the bootcamp installation for Windows 10 is blocked inside the plist file.

That's pretty disgusting.. you loyal Mac fans who held onto your cheese graters, no hardware encode or decode for you!
Not even if you upgrade to an RX580 like we told you to!
Get with the program and buy a new machine and eGPU that we halfheartedly provide support for

Only a matter of time before someone with a TB hacked MP5,1 tests this eGPU theory out.
1) Install 10.14.5 beta on a Mac Pro 5,1
2) connect the eGPU kit (assume RX580 inside) to the Mac Pro 5,1 via TB3 card
3) Check if hardware encoding / decoding is actually working.
3a) for decoding, play this sample HEVC video, and check the CPU / GPU usage
https://4kmedia.org/sony-swordsmith-hdr-uhd-4k-demo/
3b) for encoding, leave the above video open, and export as 4K HEVC, then check the CPU / GPU usage and how much time it takes.
cMP 5,1 with a Vega 56 and a GC Titan Ridge TB3 card, plus an XG Station Pro (RX 480)
Booted into Windows to kickstart the TB3 card, switched my monitor's DP cable to the eGPU
Warm-booted into macos, getting eGPU graphic signal from the 480!
Videoproc still shows no HW decoding support
4K youtube video shows HW decoding support from Chrome (screenshot attached)
What program do you recommend for the Sony vid? (used mpv in the screenshot but seems to use both cpu/gpu?)

[doublepost=1555706905][/doublepost]The CPU / GPU loading should looks like this for GPU decode.
a couple things worth noting
Apple might not officially support HW Decode/encode, but it may end up still working unofficially
second thing, the eGPU thing wont work in a MacPro5,1
because while warm rebooting via windows gets TB going, the devices are just detected as PCIe Devices not thunderbolt devices

eGPU does work... I'm running my display off of my RX480 in an eGPU enclosure
@TS: Stuttery performance.... also >300% CPU usage so I suppose we're not actually seeing HW decoding
I think LightBulbFun means "due to this eGPU will be registered as PCIe device in macOS on cMP, so, it will not give us any video hardware acceleration if Apple only allow that for TB device". But not really "eGPU won't work (can't display / compute)"
At this moment, tests shows doesn't work. But I still believe there is a "switch" in some kext can "unblock" the cMP.
This might help.
Apple released a special edition OS, Mojave 10.14.4 18E2034. It aims to support non-iGPU and non-VEGA iMac19,x with hardware acceleration. As a hackintosher, I managed to install it on my NUC8i7BEH (i7-8559U) with an RX580 eGPU hooked. I used a headless ig-platform-id which iGPU mental was disabled. FYI, you must change the SMBIOS to iMac19,2 in your EFI. Rendering a Brucex 5K took me round 22 seconds btw.
