just google for Broadcom BCM94360 Win 10 driver, download and install it, it works.


Yeah, just tried that won't install them, tried the windows support software from bootcamp too, wont install them, must have to do the usb mapping first,

I redid the BIOS patch again still won't install, does it need to be done in flashback mode? is this patched BIOS gonna brick my brand new $800 motherboard?

Only can be done via BIOS Flashback

EDIT: Bios Flashback would not accept the patched bios either



disabling onboard bluetooth gave me the ability to turn off the bluetooth on the OSXWIFI card


I did the USB mapping, used the SSDTs aren't those supposed to hide all the ports you are not going to use?
Everything is still there in the usbmapping utility

From the start though i did not exceed the port limit according to mapping util did I even really need to do this?
Im using the macPro 7,1 in the steps said i didn't need any renaming

I really Don't think i did this correctly. and now for some reason the motherboard will not boot directly from the OpenCore on the NVME ssd, will not populate in the BIOS boot list or overrides anymore no matter how many warm or cold restarts

Thankfully I copied everything to my USB stick and I can still boot OC from that but dang i must be rapidly loosing my intelect

I have had the same issue, but I found a solution! I was recently trying to flash my motherboard with the patched BIOS file and BIOS Flashback never would work for me either, not with any file, no matter if it was the one from the ASUS website or the patched file. But, after many tries and troubleshooting, I was finally able to get FlashBack to work. My problem was that I had formatted my USB stick incorrectly. I had formatted it with a FAT32 file format, but I had done so on top of a GUID Partition Map instead of the Master Boot Record (MBR) that it needed to be. Just a note, USB drives are usually FAT32 with an MBR Map, but when you have been doing Hackintoshes, the installer for MacOS is formatted HFS+ with a GUID Map. If you just reformat one of your MacOS installer USB Sticks to FAT32, it will leave it on top of a GUID Map and your FlashBAck will fail. You should be able to do a full reformat under disk utility and change this back to MBR.

Can't remember which version of MacOS was when the sleep timer slider was taken away. Probably whether the slider appears or not also depends on the Mac model (SMBIOS).

Have you overclocked the CPU?
What AVX offsets?
Did you try with all USB devices other than a mouse & keyboard disconnected and all PCIE cards other than the GPU removed?

Edit: What do the kernel panic reports say? Is there a "recurring theme" and can you share a report? Not that I am an expert at it but maybe there is something we can learn from it.
1. I have no overclocked my CPU to my knowledge. A photo of that page of my bios is included below, but here is the basic info

2. AVX Offsets:
AVX Instruction Core Ratio Negative Offset: "3" -- Current shows "3"
AVX-512 Instruction Core Ratio Negative Offset: "2" --Current shows "3" it is always different for one reason

3. I have not removed all of the hardware down to a barebones setup

Kernel panic reports are uploaded below.

Just a note...I have not removed a lot of hardware, but I did happen to notice just now that I have not had a kernel panic/random reboot in like 4 hours...the longest it has gone in several days. The only change is that right now I do not have a Thunderbolt 2 drive plugged into the Titan Ridge card. Hmmm?

Double check to make sure your usb is formatted mbr.

Yep this.

OK. I don't see any attachments, did they get uploaded correctly?

At this point I know I would remove all but the absolute necessary hardware to see if the reboots still happen.

Hey everyone! I was wondering if anyone knew if VDA decoding was possible with opencore on X299 high Sierra with GTX 1080. Thank you!

Catalina 10.15.6 update went smooth as usual with OpenCore. Finally things are smooth as Catalina was a bit rough around the edges.

Yeah fine here too with 10.15.6. I even tried Big Sur with OC 0.6.0 and it works :p
