Question: I've been running my hackintosh for 3+ years. I've been perfectly content with it, BUT if I wanted/needed to change vidcards could I just plug and play it. I'm running:

High Sierra Clover GTX 960 i5 7400

I use it for audio production with Logic. I have my NVMe, and also a backup of it on a smaller ssd (original install disk)

What I am posting below is some interesting info from a thread that is currently trying to get the AMD Vega 8 IGPU working on Mac OS. However a poster did share this info.

"So I made two discoveries recently with regards to hardware acceleration. Not sure if some of you know but what I found that's interesting is both AMD and Intel kexts in macOS /S/L/E I found share the same IOMatchCategory values under the kexts which is IOAcceleration. Unique to Intel is the IntelAccelerator IOClass which can be found in the AppleIntelSKLGraphics and AppleIntelICLGraphics kexts. I am quite sure with the info we've found so far it is possible to create a SSDT or even kext driver of sorts. We just need to figure out how to designate the AMD Vega properly as an internal IGPU.

Secondly (on a fairly related note of injecting AMD codes for acceleration), I managed to recently successfully boot up a RX6600 card in a Z590 system under Catalina. As we know the RX6600 isn't supported until Monterey, but I managed to fill in the required gaps in the Apple AMD kexts (AMDRadeonX6000Controller and AMDFramebuffer) by adding a Navi 23 class and the RX6600 device-id. I was totally amazed it booted up. This means it is totally possible to add the Vega 8 for acceleration.

Alright, that's good going - it might work for my Atari VCS. And thanks for the explanation about the IOAcceleration.

With regards to the RX6600 Catalina solution, well this is what I did:

-Made an external USB SSD install of Catalina. Disabled SIP from Recovery mode and Gatekeeper for both Monterey and Catalina (from separate installs).

Made a copy of the following Catalina kext files onto Catalina Desktop, plus from Monterey Beta in separate folder:

AMDRadeonX6000.kext

AMDRadeonX6000Framebuffer.kext

AMDRadeonX6000HWServices.kext

Reading the equivalent Monterey files, edited the Info.plist of Catalina kext files by transferring over missing sections of the AMD Info.plist (cutting and pasting) in the kexts, with particular regards to the Navi23 IOKitPersonality details and then added the FF731002 device-id to the end of it under IOPCIMatch. Saved the edited Info.plists.

Copied the files over into S/L/E, renabled Gatekeeper and SIP and then rebooted with RX6600.

I would like to switch to hackintosh just want to know if I should upgrade anything to atleast run it.

Pretty sure I can run High Sierra 10.13.6

HP Pavilion 15-bc5xxx

MOTHERBOARD: HP 8640

CPU: Intel Core i5-9300H 4100mhz

GPU: Nvidia GTX 1050

GPU 2:Intel UHD 630

RAM: 8GB 1333mhz

SSD: SAMSUNG MZVLB512HAJQ-000H1 477GB

WIFI: Realtek RTL8822BE 802.11ac PCIe Adapter (I use ethernet mainly though)

DISPLAY: 1920 x 1080 60Hz

DISPLAY 2: 1920 x 1080 60Hz

If you need anything else lmk

I'm currently running my Optiplex 3020 as a Monterey hackintosh, smbios as a macmini7,1. My internet kext is - RealtekRTL8111. Using the built-in ethernet port. Everything seems to work fine, but I have this annoying issue.

Whenever I'm downloading something or listening to Spotify, or sometimes if I even have a YT video in the background, I'll constantly get the "site is unreachable please check your internet" error. I'm not 100% sure this is my Optiplex, or my router, but it doesn't happen on other devices. and I'm able to still connect to my router's admin panel while websites won't load. I also have Windows 10 on this machine and it doesn't seem to happen when using it. I had Big Sur on this machine before but I can't really remember if it had the same issue or not.

I'm using OC 0.8.0 if that matters.

Not sure what else to include, but does anyone have any experience with this? Is it possible to fix?

I also keep seeing "volume hash mismatch" once in awhile, telling me to reinstall macos. But I'm not sure what that error means because the system is stable, aside from my internet. I've heard this is a bug with the latest version of Monterey, but could this have something to do with it? I've never experienced any kernel panics, crashes, apps malfunctioning, etc.

Good day, peeps. I've been stuck at this line this past few days. I'm trying to install Catalina. I have tried all usb ports on the device, and enabled/disbaled DevirtualiseMmio, EnableWriteUnprotector, SetupVirtualMap, SyncRuntimePermissions to no avail. Hoping someone could help me out.

Hi i want to upgrade my hackintosh from mac os Catalina to Big Sur, and this is my first time doing a major software upgrade on an open core hackintosh. Catalina works mostly good, aside from iGPU issues (dissabled it) and turboboost causing freezes (solved turning it off).

Should I update directly from catalina? Or would be a better idea to take the time and do all the hackintosh from the ground up specially for big sur?

Hardware: Intel core i9 10850K Gigabyte Vision G Z490 Amd RX 580 8GB 32 GB Ram 3200MHz Nvme SSD for hackintosh Sata SSD with a working Catalina system Nvme SSD for FCP Fenvi T919

I'm wondering if there's someone who has already installed this kext and if it works as promised. I would like to know if this will work or if someone has tested it on a Surface Laptop 3 as well. I did try it but ended messing some things around up that I needed to paste a backup of EFI folder.

Thank you in advance!

I am looking to overclocking my 6600xt on macOs, but all amd software seems to be windows only, is there a work around?

I have a fully working desktop hackintosh that has ethernet, working usb ports that recognise external drives etc. I added a 500gig hdd to my system on one of the sata ports. The drive shows up in win10 and I have moved files into it ,to use as data disk. But when I boot into Mojave, I don't even see it listed under ''All volumes and devices".

The added drive is GPT, formatted into exFAT and NTFS partitions. Using opencore. Opencore doesn't list the hdd during bootmenu as there is no EFI partition on the 500 gig drive.

Thanks for any help !

I have an IOGear GBU521 USB Bluetooth Dongle.

It shows up in System Report as: BCM920702 Bluetooth 4.0

EDIT: I've found the solution, thanks to a little more googling and the good folks at Acidanthera. I'm leaving this post up, though, in case anybody has the same dongle and is having trouble.

According to the long details on this page, Big Sur users need to use BlueToolFixup.kext instead of BrcmBluetoothInjector.kext. So I removed the unnecessary AirportBrcmFixup.kext, kept BrcmFirmwareData.kext and BrcmPatchRAM3, and swapped in BlueToolFixup instead of BrcmBluetoothInjector, did a Clean Snapshot in ProperTree, and now everything's working great.

(The rest of my original post is below)

It used to work fine in Monterey but I guess Big Sur broke something with Broadcom bluetooth stuff.

I've been trying to follow the Broadcom WiFi and Bluetooth Kext instructions from the Dortania Install Guide, but I'm not having any luck.

Do I need to install both the AirportBrcmFixup and BrcmPatchRAM kexts? Or is one for Wifi and the other for Bluetooth?

When I install just the BrcmPatchRAM kexts (BrcmBluetoothInjector, BrcmFirmwareData, BrcmPatchRAM3) and run an OC Clean Snapshot, the computer hangs at boot. It continually shows an error saying it's refusing a core dump, and refers specifically to my BCM920702 Bluetooth 4.0.

If I also install the AirportBrcmFixup.kext and do a Clean Snapshot then it boots OK, but still won't allow me to turn on bluetooth.

I have a suspicion that it's an error in the loading order for my kexts. If I don't use AirportBrcmFixup.kext, Propertree puts the three Brcm* kexts in order at the top. If I do include AirportBrcmFixup, propertree puts just BrcmBluetoothInjector and BrcmFirmwareData at the top, AirportBrcmFixup later in the list, and seems to leave out BrcmPatchRAM3 entirely.

It just seems odd to me that ProperTree puts the three Brcm* kexts above Lilu. That can't be right, can it?

Hey guys I just updated to Opencore 0.8.0 and my usb 3 went out.

Ive tried remapping my USB ports and messing with bios settings. Nothing seems to work. When I use USBInjectall kext, I get the usb3 speeds but not with my usb map kext.

Anyone have any suggestions? Thank you!
