Broadcom BCM94352Z DW1560 with OpenCore + Big Sur

[Atrahasis]

Greetings! I have managed to create a fresh install of BS using OpenCore. The main issue I have now is that the Broadcom BCM94352Z DW1560 is not working (no Wi-Fi or Bluetooth). My previous build on this hardware was Clover and it was working well under that config.

So I'm looking for any tips or pointers. Here is a tree listing of my EFI and I've attached the config file. Am I missing anything obvious?

TIA!

I believe you need to disable AirPortBrcm4360, which is now within AirportBRCMfixup.kext. There's a few different ways of disabling this within the plugins folder (deleting it from the folder), or specifying in .plist the max macOS which the kext will load for (20 is Big Sur, 19.9.9 is below this).

Fixed everything for me.

The details are here from folks far smarter than me....

Thanks @dsteib2 — I removed the plugin and tried again but still no luck . On the bright side, Bluetooth is working!

Your config looks similar to mine. Any chance you could share your EFI so I can compare?

Thanks!

It's not removing the plugin, it's removing the plugin within the plugin. Maybe you noted that already, but if not... It took me a long time to figure this out. AirportBRCMFixup.kext has both the AirportBrcm4360_injector.kext and AirportBrcmNIC_injector.kext within. By clicking on Show Package Contents you can review and delete out the 4360_injector.kext.

Attached is my config.plist too if that helps.

Hopefully this topic will provide some help.

[SOLVED] IOKit Daemon (kernelmanagerd) stall[0], (240s): 'PXSX'

When I'm booting the Big Sur installer USB, it stalls for 240s with the following message: IOKit Daemon (kernelmanagerd) stall[0], (240s): 'PXSX' The lock-up will then repeat 3 more times, and then the installation proceeds. This happens on every restart during the installation. Big Sur will...

Sorry — I haven't had a chance to get back to this and have since discovered problems with VMWare (related to networking on Big Sur) which means I'm staying with Catalina until those are sorted.

Yes, I have just completed my Big Sur Hackintosh with a HP ProDesk 600 G2 Core i7-6700T, using a BCM94352Z WiFi card. Following the instructions dsteib2 gave: (going into the AirportBRCMFixup.kext, showing Contents, etc and deleting 4360_injector.kext) WiFi and Bluetooth now work. Thank you dstelb2!!

Hello I have a strange case. I have BCM94352Z nothing makes it work - I saw a video where guy shows his card in the list of PCIe devices via hacktools.... I did the same and it's just not there. I put the stock Intel chip I had - it show ups (but doesnt work of couse) in PCI list. so my thoughts were ok - seems like my card is faulty but today I got another one from a friend of mine and it doesn't appear either.

so question
1 - is there a way to check that the card is not faulty
2 - what could be wrong if no tutorials help ?
