Hi Tony @tonymacx86 , These are classic systems and I have a few friends still running them- how was your experience with Monterey? Have you tried Ventura? can you post your EFI or did you just use the one from the first post? thanks! g\

adding in my current EFI. Also hope you dont mind @CaseySJ but tagging you because you are the master.

Hello My Hacky Fellows, Has anyone successfully gotten Ventura installed on their X99 system? I have a number of X99 Designare based systems - they run Monterey 12.6 perfectly. But I have been unable to get Ventura installed. Hangs at PCI Configuration Begin regardless of what I have tried. OC...

I have a couple of systems using this motherboard. Any chance I can get your EFI to work from? Thanks, g\

Did you ever do a Monterey guide for the Z97MX? I have this board and have it working well with triple boot 10.12/10.14/11.7, but trying to update the 11.7 to 12.6 and having a strange panic very early in the boot. Can you share your working EFI? Much thanks, g\

You should investigate if your device attaches to the decklink kext in /L/E or if it connects to the com.blackmagic-design.BlackmagicIO.DExt.dext in "/Applications/Blackmagic Desktop Video/Desktop Video Setup.app/Contents/MacOS/Blackmagic Desktop Video Driver...

I thought I would chime in here since I use a lot of these BMD devices and I have encountered and explored this issue a bit. TLDR for your issue- you must install driver version 12.1 Why? - This is the last version that has a BlackmagicIO kext installed in /L/E. Now here is where I think...

Is it no longer necessary to unlock MSR on newer BIOS versions? Gigabyte added the CFG lock option in BIOS? That was the main reason I wasn't updating BIOS since i didn't want to bother with MSR unlock again. Thanks, g\

Hello @CaseySJ, Thanks for keeping this thread so active and helpful. I am hoping you can help get my Thunderbolt card working on one of my X99 systems. I have flashed cards working very well in 3 other systems including Z390 Designare. But this X99 system seems a bit tricky. I have attached...

This is an unsupported controller. in fact i think it might be the only one that's unsupported at this point since VIA has been working for a few macOS versions now, fresco has always worked, and asmedia works well now too. Get a different controller. Ages ago we had these working with crappy...

While its pretty unlikely apple will release any rocket-lake or z590 based macs, it is still possible they will release some machines with intel CPUs. The most likely one would be an update to the mac pro. But when they announced the M1, they also said they were going to continue to support...

HDMI works if you use @CaseySJ 's lengthy opencore device property entry for the iGPU and change the device-id to 923E0000 per @benvp. g\

yep, this did the trick. at first using the very basic device property entry @benvp posted caused the HDMI output to stop working once the system boots to macOS desktop (could still connect over RDP, and macOS would see the monitor connected, but monitor would say no signal). Displayport worked...

Whats your status with this? I have this board now and would love to get it up and running 10.15.7- main issue i have so far is using just iGPU i have a lot of graphics related crashes. Thanks, g\

Would you mind making a consolidated post with your methods and files attached? i am very interested in testing with this method and making hopefully minor adjustments to get it working on some older machines and client machines (with both built-in AR and AR AIC) since it should require minimum...

But when will you be able to buy a CPU. intel supply has been abysmal for months- years even :-/ i am worried these "new" CPUs could be hard to come by this summer.

IDK, off the top of my head, i don't think there are any comet lake based real macs yet. They will likely be coming. Pretty sure the 16" is still coffee lake but i cant remember. But as mentioned, Comet is essentially the same thing as Coffee and Kaby so it will probably work- at most needing...

Just to be clear, intel has made their "nth generation" marketing very convoluted. These new macbooks will be based on 10nm "Ice Lake" CPUs which have a new architecture and iGPU. The "new" desktop parts are still built on 14nm "Comet Lake", an iteration of old Skylake architecture. So macOS...

Glad there is some rhyme and reason to this issue. Good job damaging your board :p That said, the missing parts are "just" resisters and there is a pretty good chance the board will work fine by simply bridging the space between the missing resisters with a conductive ink /solder pen. should be...

@mattystonnie This seems similar to radeonboost kext method, right? any chance of radeon vii support using your ssdt method? Thanks! g\
