Hi all,

So I have built quite a few hackintoshes over the last decade, and have usually ended up with rock solid machines. Currently, I have 2 hackintoshes, my main one being a liquid cooled i7-4770, 32Gb RAM, 240Gb m.2 SSD, GTX 980, and a bunch of other SATA SSD's for PhotoShop caches, after effects etc.. this machine has been rock solid, and never skips a beat. Currently on macOS 10.13.2..

However, my other hackintosh is where I am having some issues. It's a HP EliteDesk 800 G1 - i5-4570T, 16Gb RAM, 256Gb EVO 850 SSD, with on-board Intel 4600 graphics. Now, for every day tasks, this machine has been very stable, and even handles my 'at home' PhotoShop/After Effects/Final Cut Pro X workload. The issue I have been facing though, is that certain websites seem to make the machine hard lock. This ONLY happens in Safari, and it seems to be triggered by some sites that have video players on them. Oddly, YouTube/Facebook etc do NOT cause the issue.

An example URL that causes the hardware lockup is https://shareably.net/cat-takes-back-treats-ducks/ . If I view that URL in Safari on the HP EliteDesk, the machine hard locks within about 5 seconds. The same URL works perfectly fine on Chrome though. Also, its not just this one URL, but quite a few sites, and they all seem to use some sort of video player.

Now, the HP EliteDesk 800 G1 is currently running macOS High Sierra 10.13.2. The only (non-standard) kexts I have loaded, are FakeSMC, IntelMausiEthernet and VoodooHDA.

Please let me know what other information you might need to help me figure out why Safari crashes the machine.

Same problem. Nobody, nothing?
 
Well, you're in luck. I tracked it down to being a bug with PAVP (Protected Audio Visual Path) in non-natively supported Intel Graphics cards (HD 4000/4400/4600, as well as Sky Lake and Kaby Lake).

The fix requires 2 kexts to be added to your EFI partition. I've attached them to this post. Put the kexts in
EFI/CLOVER/kexts/Other on your EFI partition and reboot.

That’s great,
thanks
but what if I'm not using internat graphics? It is disabled in bios
 
Can you show me if there is any output from the following command (in Terminal):

kextstat | grep Azul

nope, nothing shows up

BTW: was using only chrome today and freeze also happened. Had only Adobe Premiere and Chrome opened.

Sounds like it might be an unrelated issue then, as the bug Im talking about only seems to be triggered by Safari.
 
Thank you. That solved the problem for me. I'm using an Nvidia 760 so I'm not sure why it would have been affecting me but that IntelGraphicsFixup.kext did the trick. I already had lilu.
