Why the lack of interest in using the OCLP accelerated patch for Nvidia cards?

[asiga]

I built a hackintosh (clover-based) years ago, with a Nvidia Pascal Titan, running MacOS Sierra with Nvidia drivers (in fact I'm typing this from this very same machine). The point is that I need to work with relatively big gfx cards (mainly with OpenGL and OpenCL), and this hackintosh offers a great performance for both OpenGL and OpenCL with this Titan gfx card.

Now Sierra, and even High Sierra are very old. But I cannot get gfx acceleration for the Titan in newer MacOS releases with the official Nvidia drivers because they don't exist for anything newer than Sierra.

This summer I learnt the advances done in the field by the OCLP approach. And there was even another forum's thread showing success in getting the OCLP gfx patch working in a hackintosh with Nvidia Pascal cards.

I went to the OCLP discord community, and they say "OCLP is for real Macs" and "you are on your own getting it to work in a hackintosh". Fine. I can understand the OCLP community being interested in old Macs only. It's fully understandable that each community has its own interests.

Then I searched in hackintosh forums, and I find that the reply is the same: "OCLP is for real Macs". This reply I don't understand. I mean, macOS is supposed to run in real Macs, not in hackintoshes, so why do you care about OCLP being for real Macs if you are installing macOS in a hackintosh to begin with? I could understand finding messages in the lines of "it's not clear how to do it", but most of the times what you find is not lack of knowledge, but lack of interest, or even some sort of dislike towards OCLP.

What I mean is that I really miss finding a hackintosh install guide for Nvidia Pascal cards on recent macOS releases, borrowing the accelerated patch from the OCLP community and using it for hackintoshing.

I'm sure this post is well meaning but it has a strange gist: It makes it sound like there's a politics of interest in solutions, and a rhetoric of sealing things off from consternation.

But a another explanation is that you happen to be the first one with an interest.

In these communities, work gets done when interested people start looking for approaches, testing things out and publishing there successes.

If you can't find anyone else who has made progress, then it's up to you to lead!

So create a topic worth discussing. Go get OCLP, tear into it to find the parts that pertain to Nvidia, study these parts, discuss on discords, pull what's needed into a hack OC and publish your findings.

If what you build useful, the rest will come.

OTOH if your question is only "Why hasn't anyone else done the work I need?", an empty or deflecting response is to be expected.

You could compromise and ask "What barriers prevent reuse of OCLP Nvidia work-arounds in hacks?" and if the only responses you get are "OCLP is only for Macs" that's a sign that no one who's read your post knows the answer—or there's an overwhelming barrier that's so obvious among the cognoscenti that the question is considered to be dumb.

I don't know.

Whatever, you are free to investigate OCLP by dissecting the EFI that it builds and asking questions about its structure. This west you are likely to get more traction from community, especially those with similar interest, than by lamenting that no one has yet done needed work for you.

Best in your pursuits

To be honest, I don't think I'm the first one in having interest: Support for Pascal Nvidia cards is sort of a FAQ in the forum. The standard reply is "they don't work anymore". But reality is that they can work with acceleration, even if the status is experimental. Given the interest that there seems to be in getting 10X0 cards working, I really find it strange that there's not a guide. Look at this thread for example: https://www.tonymacx86.com/threads/...-nvidia-pascal-graphics-fully-working.320531/

Hi there.

There's no bias here. If you can get OCLP to do a certain job - and it is verified as working - then of course the community will jump on it. It is true that OCLP was created for real Macs, but you are correct - there's no reason not to use the tool if it helps a particular problem.

Basically, it is used to make newer versions of macOS run on older hardware, currently the focus is naturally on Ventura. There's a list of old GPUs that it will support in this task:

The OP states Pascal - the GTX1050 in their screengrabs - and Maxwell work. Okay, but it's a bit remiss of the dev not to mention that because Pascal was big and used by many.

If it is genuine then why not post a guide about how they did it? Why no more info in the post?

The OP has made only 3x posts, two just saying OCLP activated a Pascal GPU with hardware acceleration. But look, can you see in the screengrabs, there is no Metal support? Metal is the new framework for later macOS versions. The third post by the OP does actually state that Metal does not work.

So it is promising in that the dock and menu-bar are translucent, but how much of that Pascal GPU will be usable with no Metal support?

Yes, we need a guide.

asiga, that is not quite true. Ignoring for a moment OpenCore Legacy Patch, High Sierra will run with full acceleration. Please link to this page and read post #12.

Yes, I know, I meant HS. I don't see any advantage in updating this box to HS, because less and less software is supporting it. High Sierra is reaching the point of being dropped by new versions of web browsers, and this is usually the point where the machine stops being usable for usual tasks. Yes, I still use HS (and even Snow Leopard on a MBA, and Tiger on an iMac G5, but these two machines are no longer usable for anything that requires security in the web, and High Sierra is getting closer to that point year by year --not yet, but think this again a year from now).

Because I like to use the Pascal Titan, maybe I'll need to install Linux in the mid-term. I'd prefer to continue with MacOS, because it's more comfortable and usable for me, but that will depend on how the OCLP patch evolves...

It's worth pointing out that the Nvidia web-drivers had their certificate revoked and will no longer run. Unofficially Nvidia did put out an update with a new, signed certificate, but only for the latest version of High Sierra.

Here's the link:

... but as you are not interested in High Sierra, then this is all academic I realise.

Sorry I couldn't be of more help.
