Disappointing, but useful information.

Has someone tried to run Photoshop/Lightroom on a Zen 4 hackintosh without any software patches, AMDFriend or other?

If I'm not mistaken, the issue with ProTools and Ryzentoshes is the same as for Photoshop or Lightroom: Some AVX-512 accelerated functions do not correctly detect the processor abilities and fail or crash the software on Zen 3 and earlier. But Zen 4 has AVX-512. The question is then: How do we...

Historically, x.2 or x.3 updates is the time where Apple drops a "surprise" on us. Big Sur broke the USB port limit removal patches. Monterey enforced DriverKit and AppleVTD for networking. It looks like you've identified the "Ventura special": Apple may have dropped ATAPI support. If so, it...

Thanks! I had missed a few bits of the Maple Ridge story.

I think I had a reasonable command of the situation and my situation was spot on: Apple has never used Maple Ridge in a real Mac, and quite possibly never will. MacOS has no driver for Maple Ridge. All efforts to spoof it as Titan Ridge have failed, and the Maple Ridge firmware has not yet been...

Simple: Get a Gigabyte Titan Ridge card, preferably on a motherboard with a 5-pin header; hot plug with a SSDT, full Thunderbolt bus by flashing the card with a custom firmware. Do not buy into Maple Ridge if you need dependable Thunderbolt. Efforts to make Maple Ridge work have stalled, and I'm...

RX 6700/6750 are NOT supported and will certainly never be, so this is an even worse choice than RX 7900.

Then the best part of the plan would be the waiting… A W7800 upgrade would make sense even after the MacPro7,1 is discontinued and replaced by an AppleSilicon model. (No guarantee Apple will do it though.) But if Apple discontinues the Intel Mac Pro, an upgrade to the low end W6600 would make no...

Then, why not wait for RX 7800 (XT) to be announced? Contrary to macOS support, which is uncertain, we can be fully confident that these parts will come—once AMD has extracted enough money from early RX 7900 adopters.

That's a hint I got from the documentation of… WhateverGreen: Beyond managing ALC codecs, AppleALC "corrects" the sound part of video outputs, and possibly fixes other sound-related things to make the system more Mac-like. Since AppleALC(U) is not necessary at all for USB-based codecs, I infer...

Actually it expects the cores NOT to be named C000 in scope _SB.PLTF, since it was it does is defining stubs which macOS understands. How teh stubs are named is irrelevant as long as it does not collide with the existing processor devices in ACPI devices. Whenever possible yes. But a SSDT which...

A RX6650XT (0x73ef) should be spoofed to a RX6600XT (0x73ff) to work with macOS. This spoof will itself require the card's location, and thus depend on where it is plugged. Does it work with Windows when plugged into the top slot? If so, use Device Properties to obtain the PCI and ACPI paths.

Flashing the card is only necessary if the device requires the Thunderbolt bus. I have no idea whether this is the case with this Octo Satellite. To check whether Thunderbolt is enabled and how the Octo is connected, use IORegistryExplorer and scroll to find where the Octo appears. Or just check...

@CaseySJ is the Master here. SSDTs depend on card, motherboard and slot used, so it would be best to open a specific thread and describe your hardware.

Thunderbolt works fine with any version of macOS… if using Titan Ridge (Thunderbolt 3): Hotplug with a SSDT; full Apple-like Thunderbolt implementation with Thunderbolt bus (required for networking or DAS) by flashing a custom firmware (somewhat breaks TB with Windows). The Maple Ridge...

1. May be considered. As an alternative to a whole new quirk, the two "compact" patches may be added to the template Sample.plist, in disabled form. 2. It was already done for OCAT, so why not OCC? 3. Easiest to do and to maintain. Lowest reach of all options, as potential users would have to...

By nature, ACPI tables are independent from OC version. What kind of SSDT do you think would be useful to enable a NVMe drive? At most, you have to test with and without NVMeFix.kext. But a SSDT?

@CaseySJ Many thanks for the above two posts. They make a simple, straightforward matter of summarising what had to be tracked down bit by bit while browsing through Darwin code source for documentation between two sips of coffee by the fireplace. A normal hacking day… With the Intel-related...

Wouldn't that cause issues for Intel systems where Aquantia NIC work with the current quirk (spoofing?) and AppleVTD enabled, if this case occurs? The patches potentially apply to all AMD systems and to Intel systems without AppleVTD. A new quirk, to be activated independently of...
