Hey guys. Same problem here with my Acer laptop. Any news on this? I agree this may be a embedded controller issue, people has been confirmed no errors on AppleALC for CX8400. @theroadw, VoodooHDA works for every audio port to you? (mic, speakers, phones) Using it makes my laptop speakers work...

I'm preety sure XhciPortLimit quirk is only used on the discovering process of USB ports. After getting your 15 (or less) ports configured, it has no effect anymore.

Hey @cramletram, I've been using Opencore with Catalina and Big Sur and made some modifications on my initial USB config. Attached the Opencore 0.67 EFI folder, without both SMBIOS (Generic item info) and Resources folders. In this setup, I use USBMap.kext to config my USB ports, but you can...

No, it doesn't, only bluetooth. Initially, I tought could be a windows driver issue. Gonna send it back to the store. Anyway, thanks a lot for your help.

Still nothing. I don't understand why it even doesn't show up on the DPCI Manager PCI List.

Do you mean putting AirPortBrcmNIC_Injector.kext BEFORE AirportBrcmFixup.kext? It's about power management/sleep kernel panics on some Ice Lake laptops (like mine). See here.

I made a revision of the applied patches before send you new files. I don't exactly why it happens, but the brcmfx-driver=2 boot argument seems to be not saved on the config.plist file at the first time. (I suspect a NVRAM issue.) So, I did ensure the boot argument was applied and rebooted the...

I deleted the AirportBrcmFixup.kext somehow before send you the files but it is there for sure. Added the brcmfx-driver=2 boot argument but still nothing. (Also tried brcmfx-alldrv boot argument.) I used itlwm kext before, for Intel wifi. Could it messed up my network configurations? There is...

Hey @Feartech , I have the same BCM4352Z as Miszel but can't make wifi to work, only bluetooth. Have enabled all kexts needed, but still no success. Attached my Opencore 0.66 Folder. macOS 11.2 Big Sur Note: there are some patches regarding IC2 Trackpad debuging. Thanks

Same difficult here. Tried to follow Feartech guidance but didn't succeed. I know that my I2C device (trackpad) is TPD0, but can't understand the HEX code from Feartech to make my custom patch. Tried a patched DSDT before but BigSur / Opencore boot hangs near the middle of loading bar. Thanks

Same problem here with my Fenvi BCM4360. Already revised USB patch and last changes applied. Actually, the machine was working (and sleeping) pretty well just before the wifi card install. Thanks to gn01650966, will try to connect it to the USB 3 internal connector as a workaround.

Ah yes, now I understand... Big Sur is coming. A good reason to wait a little more and look for compatible graphics cards. Tried to find my connected HDMI in hackintool inside Catalina but no way.

I can run it on my new Catalina drive. I agree, no problem to buy a new AMD card, but pull over my GeForce 970 that I still use for games in Windows. hahaha are you kidding? Framebuffer patching is old-fashioned?

Hi guys, I've been running my Z390 over High Sierra since there is no support for Nvidia on Catalina, but now I'm trying to figure out the UHD630 framebuffer for this MOBO, which has only one HDMI video connector. I'm using Hackintool V3.4, there are some differences from the old version this...

Thanks for spending your time with my mobo issues but none of the alternatives worked. I am not that skilled guy, so will wait for someone eventually find the correct configuration. I'll be in touch. Tks

Great! Will try tonight, thanks. Also, yesterday I connected the computer directly to a TV (HDMI port, without an adapter). The image got better, but after a while the floating dead images start to flash intermittently. My guess is that the adapter puts some noise onto the signal, but the issue...

Thanks. So, @manfriday, I think we can delete the Hub1 section from our SSDT.

Yes, you're right, it's a fine tunning I didn't touch. I understand that "internal" is used for onboard devices (like bluetooth), directly connected to the board (using an USB port). So, in this case, HS11 and HS13 are not internal, because they connect the board to external devices, (through...

Ah yes, it has been a long time... :) Nice! That's worth a try. Yes, it's a good idea. Will try later.

Fixed, thanks.
