I’m failing to understand what your statement have to do with the early-2008 Mac Pro support of AMD GPUs and the Apple AMD driver requirements.

I'm thinking they are referring to the fact that Windows users can use new AMD cards, without SSE 4.2. Phenom II's I think are limited to sse4 or 4.1.
Meanwhile we have a Phenom II PC with RX460.
You can use an RX460 in a 3,1 if you only use Windows on it. Why have a mac pro at that point?
The SSE 4.2 thing is only forced to DX12 use in Windows. The card still works for basic use and anything not inDX12 mode. However if I was using a pre sse4.2 PC I'd just use a Geforce to avoid the issue all together.

It has SSE3 but not SSSE3.

It also has SSE4a.

Most games don't even need SSSE3.

The Steam survey now normally shows that the whole Mac,Linux,Win user base would be SSE3 (SSSE3 for Mac).

Maybe #17163 is a solution? It's a kext that emulates two missing SSE4.2 instructions used by newer macOS AMD drivers. It also lets me run World of Warcraft and Classic WoW on a MacPro3,1 running Mojave or High Sierra with a GTX 680 (but there's a strange problem with the text drawing).

I have a sapphire pulse rx 580 4gb “oc” and a red devil rx 580 8gb dual rom. The devil takes up 3 slots so I moved it to a different machine and got the pulse for in the 3,1 instead so that I could access my slots again.
I used the netkas patch and the disable library validation kext. I loaded refind and a clover driver for boot screen support.

I have the"DisableLibraryValidation.kext" file, but I am unsure about where to put it.
The Netkas site seems do be down, so no help from there.
Looks interesting. Could you, please, elaborate on this?

Installed here:
Code:
/Library/Extensions/DisableLibraryValidation.kext

Set permissions, and manually loaded it, updated caches, then rebooted and swapped in my RX580 card.

This happened to be my boot drive (disk 5) this command output is from
Code:
diskutil list
Code:
/dev/disk5 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *1.0 TB     disk5
   1:                        EFI EFI                     209.7 MB   disk5s1
   2:                 Apple_APFS Container disk7         822.6 GB   disk5s2
   3:                 Apple_APFS Container disk6         116.3 GB   disk5s3
   4:                  Apple_HFS old-installer           40.4 GB    disk5s4
   5:                  Apple_HFS Installer               20.4 GB    disk5s5

Code:
Mac-Pro:~ ludacrisvp$ sudo mkdir /Volumes/EFI
Mac-Pro:~ ludacrisvp$ sudo mount -t msdos /dev/disk5s1 /Volumes/EFI

Installed rEFInd with GOP support and added the highlighted driver for display support between the rEFInd boot picker and the OS splash screen (this gives things like verbose boot support / single user mode)

Get this version of rEFInd from here:
https://drive.google.com/open?id=1qrXbRiFIfqeqaxgmZ8tPGQn4PIdLL_Hh

Then add the OsxAptioFix2Drv-64.efi to the drivers_x64 folder.
I grabbed mine from here:

Anyone know if the Netkas patch is being hosted anywhere in particular with the website being down?

Not sure if this is ok to do per forum rules but here is a copy of it I had stored on my phone.

EDIT: Replaced attachment -- somehow it was corrupted, new copy uploaded.

With the 3,1 you can use , say an nvidia gtx680 which is supported and has metal, the install Mojave with the dosdude patch and the machine runs just fine. I have done it. Also the nvidia gt640 works. I imagine the 7950 and 7970 amd cards work too.

No, no AMD cards work with MP3,1 at all starting with High Sierra, that's why the patch for RX 4xx/5xx SSE4.2 emulation exits.

Hello,

I tried a whole Day and Night to make it work but I failed.
Can somebody please give me detailed instructions on how to install all that?

Also, I can't extract the bz2 fixed Metal Driver from Netkas, every Archiver gives me an error.

I really need your help :/

Installed here:
Code:
/Library/Extensions/DisableLibraryValidation.kext

Set permissions, and manually loaded it, updated caches, then rebooted and swapped in my RX580 card.

Unfortunately, I still can't get it to work. The screens just sit there, with the power-lights flashing. It just as if the computer is turned off (or pot to sleep). However, the fans spin up, so I must assume that the card gets power.

1. I assume that you really mean /Library/Extensions/ as the path to where to install the "DisableLibraryValidation.kext" file and not System/Library/Extensions/, where the patched "AMDMTLBronzeDriver" bundle resides.

2. Using "BatChmon" I've set the permissions to:
Owner: root (RWX)
Group: wheel (R-X)
Everyone: (R-X)

These are the usual settings when asked to set Permissions (and the same as the original "AMDMTLBronzeDriver" File.

You also say to "manually load" the kext file and update the "cache". I'm afraid I don't know how to do this. An explanation would be appreciated.


Oh, by the way. After removing the RX580 card and put the original HD 2600 XT back in, the screens work just fine.

Dosdude's Catalina Patcher includes the mouSSE SSE4.2 emulator. Mac Pro 3,1 + RX570/580 + Catalina Patcher works without issues.

(The Sapphire RX570 Nitro will block your Slot 2 though.) ?

Thank you. What a brilliant hack by Dosdue, to have included the sse4.2

The slot 2 will pose a problem only if i were to add another card right ? Or are there any other issues. Thanks
