Thanks.
The update with hex edit method is also applicable for the Radeon RX 580 Special Edition Nitro+ 8GB?
Got a tip for us?

Hex edit method should work well for all RX580 in 10.14.6.

If you follow the exact method as per this post.

Then you can simple turn OFF hwaccel -> update the OS - > Turn ON hwaccel.
UPDATE: I'm wrong. It does replace the hex-edited version! Thanks kohlson!
I just did the update to 10.14.6 and the modified AppleGVA.framework was NOT overwritten. (I did make a copy of it just in case). No issues! Crossing my fingers that it adds more stability to my system. My 5,1 has been pretty stable the past few weeks with the occasional hard crash.

I can confirm that there is no update of AppleGVA.framework. I checked the file version.
However, I cannot guarantee that the modded file won't be replaced. So, my personal suggestion is turn OFF before update, then turn it back ON after update.
In the interest of science ... I just completed an update from System Preferences-Software Update.
It looks like the AppleGVA file was overwritten - jellyfish no longer plays.
The date on the file is July 16.
The "before" hex string is in 2 places.
But I can verify that following the instructions, including the permissions changes, still work with 10.14.16.

Yeah, the date is 16 Jul, but there is no change in the file version, still 11.10.16.
Thanks for that! You are correct, sir!
I disabled SIP and replaced the AppleGVA.framework with a copy of previously modified file I had saved and rebooted. All better. That Jellyfish video plays like a charm now.
Does anyone know if this mod is confirmed to work with the AMD RX580 running under High Sierra 10.13.6? I need my Mac Pro to run High Sierra for some software. Thanks!
Hi, just a quick update:
I got the Vega 56 - updated all the software: OS to 10.14.6 & FCPX to 10.4.6 (before I was on 10.4.4 - for plugin reasons, somehow an old flicker plugin didn't render well in newer FCPX) did the Hex method. So far no freezes. Replaced back to RX 580 for testing, also seems it's now ok. Running through a timeline with effects which caused the freeze screens before: it's ok now.
Starting now a new project, with a lot of Fuji XT3, HEVC, 10 bit, 4k video files - fingers crossed nothing goes wrong.

Thanks for the report.
Hopefully you can bring us more good news that no more system freeze with RX580.
The used Vega56 is quite cheap now. If you must stay at HS, and really want to use hwaccel, you should seriously consider to get a Vega56.
In your opinion; is Vega56 equal, faster or less than the RX-580? I maybe thinking of building an eGPU for my Macbook Air and transplant the RX580 into it and get a used Vega56 to put inside my Mac Pro if that is what it takes to get hwaccel.
Thanks, please use it for a few days and report back if it's stable.
I will keep testing the hex edit method on my own cMP.
Some little problems during editing frame by frame, like this...But when I press play, I don't see these artifacts. Now i'm exporting and will see if there are same problems also in the final result
EDIT: ahi ahi ahi...also in the final result I see artifacts every 1 second!

Do you mind try the Hex edit method? I really want to know if that make any difference.
I have a lot of fear to try this, because i never utilised a HEX editor...can you suggest a free one to download?
Tomorrow morning I will try
Never used one, until I executed this on my RX580. I used iHex, which was free from the App Store. (check and check). Two quick notes:
- I was careful to copy and paste from the instructions to the Find and Replace files in iHex.
- I opened the file by first opening iHex, then dragging the GVA file to the dock icon.
Note that when you save, you get a message saying something has also modified this file, Save Anyway.
I did this when you originally posted it and it worked just fine and survived the .5 to .6 transition. I got curious so I decided to see if it worked with a second GPU and it doesn’t seem to scale with my RX480’s it’s like the second GPU isn’t there.

I never think about it. But I don't think hardware encoding / decoding support multi GPU.
It's a very close loop operation inside the GPU. If want multi GPU support, that will need something like Crossfire. Allow the GPU talk to each other, then encode / decode every alternate frame etc.
I haven't search anything in this area, but I really don't think this kind of software support exist.
It was worth pulling a couple screws from the hackintosh to find out if the acceleration scaled and now we know.
"One slot" means "20mm wide", which doesn't exist. But if you mean "only occupy the slot 1 in cMP", then any 40mm (dual slot) wide card can do. All reference Vega56 are dual slot design. Besides, XFX, Powercolour, etc also provide 3rd party option Vega56 which has better cooling, but still dual slot only.
