[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

[Itshuta]

On the z390 board, if you use the 2nd m2 slot I believe several sata ports get disabled. Check the bios to enabled/disable this & the manual

At the very least you should be able to hit F12 or whatever the bios key is & boot from the 2nd m2 with windows on it and isolate the issue to a bios setting or clover config.

Yes. Check p29 of the MB manual.

Due to the limited number of lanes provided by the Chipset, the availability of the SATA connectors may be affected by the type of device installed in the M2. sockets. The M2M connector shares bandwidth with the SATA3 4, 5 connectors. The M2P connector shares bandwidth with the SATA3 0, 1 connectors. Refer to the following tables for details.

Anyone know how to resolve the "Bluetooth not available" error with that squiggly line through the menu icon ?

I've tried every possible combination of unload/load/pkill, etc., etc., to no avail
I've written enough shell scripts at this point with various things to try & fix this.

sudo kextunload -b com.apple.iokit.BroadcomBluetooth20703USBTransport
sudo kextunload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport
sudo kextload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport
sudo kextload -b com.apple.iokit.BroadcomBluetooth20703USBTransport

etc., etc.

I know a reboot fixes this issue, but its so intermittent its just annoying

Some things to check:

• IORegistryExplorer --> XHC section: Check that HS14 is not present. This is the Intel CNVi module that we need to disable in order to use a Broadcom Bluetooth module.
• Check that the USB data cable from the Broadcom WiFi/BT module is securely connected to the internal F_USB header (USB 2 header).

Nope, IOReg shows HS03 - HS12, no HS14
Yes, header is connected securely otherwise & just checked it again

Now, I do remember back in 2018 setting all this up & you helped me get my intel gfx working with bios set to iMac 19,1 and I think I may have mentioned that I had intermittent connection with the Apple keyboard & trackpad

After about a year of this I gave up & switched to the logitech mx keys, which oddly also gave me issues connected to BT so i just switched to the dongle & its been working every since.

I think this issue manifests itself when the machine goes to sleep & wakes up & random decided BT is not there despite the chip showing up in the system report.

Can't reboot at the moment as this is my main machine, but I can check for anything else that may come to mind

On a dual boot system is anyone getting an unknown device in Windows? Here is what I am getting, does this have to do with Opencore or anything, as I don't remember getting this with Clover.

 

[Itshuta]

Is there a post install post more focused on the opencore build with Big Sur ?
Or are the steps pretty much the same ?

@CaseySJ Hi, I have a weird problem with UHD 630 on BigSur. BigSur UI animation is not smooth with some kind of lag. When I click Launchpad, Stacks on Dock or Minimized windows or Safari, etc. getting this lag. I am using OC with the latest kexts. I tried many framebuffer patches either with different settings everything working (full acceleration, VideoProc shows all ok, VDAchecker also ok.) But this lag never goes away.

I am using Dell 4K monitor. And looks like some kind of 4K issue. Cause when I setting full 4K UI much smoother. When I choose another scaled version UI starting lag. Do you have any idea what could that be?

Hi Casey, I’ve suddenly started getting this code signing error at boot. It happens a few times, then I can get it working again after . Swapped out for my backup and it’s the same for some reason. Any ideas what it means?

Post-installation is actually not needed with OpenCore because the EFI ZIP file is also fully configured.

If you use the latest OpenCore EFI, the unknown device should disappear because all SSDTs in that EFI folder are applied conditionally for macOS only. However, if you have a Broadcom WiFi/BT card such as Fenvi, it can appear in Windows Device Manager with an exclamation or question mark. Because Windows can use the Intel WiFi/BT module, we should actually not install Broadcom drivers in Windows.
