to be fair, buying one of those things in 2019 isn't necessarily a very smart idea, considering that it was essentially the same price as in 2013, the hardware didn't change, hence you were overpaying more and more for older hardware. This is even more true when apple announced the 2019 Mac Pro at WWDC. Unless it was for urgent enterprise reasons, there really wasn't much of a reason to buy the 2013 Mac Pro in 2019.

You are absolutely right, but they DID sell it in 2019. It still should have a bit more of a lifecycle. Especially considering the cost.
No denying that tech has moved on. And, the MacPro6,1 is thermally awful, but I would think that support should continue a bit more.

Alright folks, news has broken that legacy metal has acceleration patches! However, as they are not released, I ask everyone to please refrain from asking how to install ventura with the patches! Thank you for your cooperation

You missed a key word, preliminary, there are important elements that are broken...

These are in no way stable nor recommended for users to install. There are still many issues and there is no guarantee that what is currently up on the repo will remain in a usable state (unless you are instructed to test or if you are developing, you should be sticking to the tagged releases anyway). The nightly link was specifically removed because people kept downloading them without understanding that those builds were in active development and had a high chance of being broken.

Please refrain from announcing things like this and portraying yourself as someone of authority on this subject if you are going to ignore such key information.

I am not defending anyone, but I think @0xCUBE's "...However, as they are not released..." does infer "preliminary", and he goes further to write "...I ask everyone to please refrain from asking how to install ventura with the patches!..."

Hopefully, Skylake doesn't need root patches at all, but my (very early) research has stopped because I no longer have access to a Skylake Mac for testing.

If anyone is willing to offer up a Skylake machine (iGPU only models) for development, please get in touch.

Don´t have such here, but can offer to test the AMD D300 in one of my Mac Pro 6,1 later down the road...

Possibly stupid question. With the new gpu patches, does this mean that dual graphics system will function properly, or will we be required to disable automatic graphics switching?

TLDR: Both gpus are supported separately, but do they talk to each other?

should disable not supported one otherwise get panic. (Uninitialized NVIDIA GPU driver returns false) for nvidia use nv_disable=1 .. used to be able to delete kext but now its too much work to do that due to protections

what about 4400/4600 and P4000? I am trying to look at the source code of oclp and do the patches manually

This OCLP (Alpha Ventura) can enable HD 4600 in my Z97 Haswell hackintosh & Nvidia Kepler in Skylake hackintosh successfully. Both hackintoshs use SMBIOS of iMac19,1. Thanks for OCLP dev team !

I try to understand AVX and AVX2 support apple removed AVX support so Sany Bridge vs Ivy Bridge left without Ventura support. But the question is AVX support is referring to the processor or the HD graphics implicit in it. Can Ventura be used with an external graphics card such as Radeon or Nvidia Kepler?

AVX and AVX2 are features of the CPU and not the GPU. External graphics still works in Ventura on machines that supported it in the past (and which are supported by Ventura). Only certain newer Radeon graphics cards are officially supported.

AVX, AVX2 are extensions to the x64 instruction sets that more recent iterations of Intel and AMD processors support.
More and more programs, drivers, kernel extensions, frameworks and libraries are compiled to take advantage of those instructions. Has nothing to do directly with the GPU, but of course some drivers for some GPU architectures are dependent on AVX etc.
Some fixes have been found in the past to work around this.
Ventura is also requiring AVX2 on the intel platform (different story on Apple silicon, of course). But for reasons of emulating x64 through Rosetta2 Apple has still included a hidden way for "unsupported machines" to still run Ventura on CPUs as old as C2D.

AVX is a CPU instruction set, similar to MMX, SSE, SSE2, SSE3, SSE4. They are vector instructions that operate on vector registers instead of scalar registers and they can do multiple operations in parallel.

My username is actually an SSE2 instruction.

beta 6 of Ventura installed OTA 1.13gb (I think) without issue again on mid 2014 MacBook Pro here’s holding out the graphics patches work when final release makes it.
