They are stuck with intel because of thunderbolt.

Thunderbolt is an open protocol now. They are not stuck.

Is that true though? As far as I know the Spec has been donated to USB and will be included / published as USB4 by the end of this year.

So until USB4 is out, it is not Open "yet". And even if USB4 is out, there is no guarantee USB won't mess up with only USB4 4x4 that support Thunderbolt 3 40Gbps.

Do you have drivers for everything? Do you think it would work on a Threadripper with many NVidia GPUs as well?

Many nvidia card don't have driver for mojave or catalina. No 9xx nvidia gpu or later on can work

Correct, the built-in drivers only cover the "Kepler" architecture, as that was the last one that Apple used in a Mac. The 3rd party Nvidia drivers which support more modern GPUs are only offered up to macOS 10.13 High Sierra.

The technical background for this is that Metal and OpenGL acceleration requires the GPU driver bundle to be loaded into a process's address space. (effectively a dynamic library) With 10.14, Apple has enabled the "library-validation" codesigning flag just about everywhere, which means that only libraries signed by the same developer as the process's main executable or by Apple can be loaded into a process. Hence, 3rd party GPU drivers won't load in WindowServer for example, which makes them dead in the water.

Apple could of course implement an exception or sign Nvidia's driver, but so far it looks like they're not interested. Perhaps there will be a solution to coincide with release of the new Mac Pro which once again contains PCIe slots you conceivably might want to fill with Nvidia cards, but I wouldn't count on it.

(FWIW, my company maintains the macOS driver for one of 2(?) manufacturers of USB graphics adapter chips, so I have a pretty good idea of how the macOS graphics stack works.)

For those who might be interested for a cheaper alternative - Intel Xeon 8280 QS is $1,800 USD each, a pair of those (56 cores) on a supermicro mb with 12 x 16G RAM is about $5k USD. It has an impressive Cinebench R15 score of 7,800+

The article itself gives the price of $10,009.

Incidentally, the cost of the Xeon Platinum 9200 are also given in the article.

I do have an AMD Hackintosh, I don't see any reason you wouldn't be able to use these as a dev Hackintosh machine. It's gorgeously fast with my Ryzen 2700x, eats compilation time like no one's business and it's stable. And it's something around 1/4th the price of the same horsepower from native Intel Macs. I can't imagine the cost delta of a EPYC Rome Hackintosh to its Intel counterpart. It's not like I cheaped out e…

How about those adobe applications? I heard that PS, Pr, or Ai need special patch to run on amd machines

I'm actually a designer, but I stopped using Adobe a very long time ago for unrelated reasons — when they switched to the subscription model. For that reason I didn't even try to run them.

I do realise that might be an untenable position for someone in Hollywood since FCPX is not a match for Premiere / After Effects at that level, however, there are plenty of other things that do the job of Photoshop and Illustrator, and they are not alternatives, Sketch is genuinely vastly better than Illustrator, and for Photoshop, there have been quite a few alternatives that the whole class of image manipulation apps got commoditised.

Where do you get the $1,800 price? Intel says the recommended price is around $10,000: https://ark.intel.com/content/www/us/en/ark/products/192478/...

I clearly mentioned it is an XEON 8280 _QS_. You can buy from ebay.

Do you have drivers for everything? Do you think it would work on a Threadripper with many NVidia GPUs as well?

No, generally if you're doing the Hackintosh the modern way, you pick your components beforehand from those supported by Mac OS natively (which are excellent components you should already be picking regardless, with the exception of GPUs), and then the only thing you need is the SMC driver I mentioned. I didn't build this machine for Hackintosh, so I have a few drivers (4-5 I think? It tends to need fewer and fewer every OS X update), but that's it.

> Threadripper with many NVidia GPUs as well?

Yes, it works with Threadripper, but not with NVidia GPUs, but that's because regular Macs don't work with NVidia GPUs as well. My understanding is that it's a standoff between NVidia and Apple largely due to NVidia's poor behaviour the last time NVidia was included in Macbook Pros around 2012.

I suspect apple will release comps with amd cpus, but hackintosh with amd is already good to go

I doubt that, think of the amount of r&d they pour into arm for mobile. ARM will be their next platform for Macs.

If apple complete the switch to arm I guess the hackintosh will go into hiatus for a long time. But the recent release of Mac Pro might delay the change for sometime. However this also depends on whether the t2 chip will be forced on in later os

OP said "QS" these are grey market chips, QS means Qualification Sample, Intel sends them to various manufacturers to test with motherboards and then they leak into the grey market. They are not retail so frequency and other characteristics might differ -- but even their stability might not be as high as a retail one. Although QS is usually better at this, it's ES (Engineering Sample) which can be very dicey.

I still will use adobe apps and the main reason is my university offer them for free. But I agree adobe’s subscription is an overkill for personal use

actually Asrock release X570 for ryzen2 with PCIE4 and thunderbolt 3 ( https://www.anandtech.com/show/14455/asrock-x570-aqua-heavie... ).

Now that’s some great news. I want an AMD Apple system now.

The downside is the motherboard is pretty expensive. And I don’t think many people would buy a motherboard more expensive than the cpu on board. ASRock might offer a few more X570 mb with tb3, but I haven’t checked
