Broadcom FullMAC Wi-Fi support on macOS Sonoma, Sequoia and Tahoe without root patches

[Austere.J]

Apple Broadcom Wi-Fi Companion (BCMC)

Revive your legacy Broadcom Wi-Fi cards on macOS Sonoma, Sequoia, and Tahoe without root patches

 

 

>> Prologue

 

I started this project when Apple released the first developer beta of macOS Sonoma because I am not very fond of modifying the root volume and downgrading the entire wireless networking stack. While working on it intermittently, I have a relatively stable prototype and would like to invite folks to join the public beta testing.

 

Please use this thread for general discussion and test reports.

 

>> Introduction

 

Apple Broadcom Wi-Fi Companion (BCMC) is a macOS kernel extension designed for selected Broadcom FullMAC Wi-Fi cards. It consists of a device driver that configures legacy Wi-Fi chips and a Lilu plugin that ensures compatibility with Apple's new Wi-Fi driver.

 

The following information might not always be up-to-date.

Please refer to the GitHub repository for current information.

 

>> Supported Systems

• macOS Tahoe
  • 26.0 (25A354)
• macOS Sequoia
  • 15.7 (24G222)
• macOS Sonoma
  • 14.8 (23J21) (Not Verified Yet)

Note that other systems have not been tested. Old systems will not be supported due to the maintenance burden.

 

>> Supported Wi-Fi Chips

• BCM43602 (0x14E4, 0x43BA)
• BCM4350 (0x14E4, 0x43A3)

Note that SoftMAC Wi-Fi chips are not and will not be supported.

 

>> Current Status

• BCMC is undergoing public beta testing and is not intended for daily use in production systems.
• BCMC has been tested under macOS Sequoia 15.7 and macOS Tahoe 26.0.
• BCMC has been tested with multiple network speed tests and achieved a download speed of about 500 Mbps and an upload speed of about 300 Mbps (Test Environment: Indoor, 802.11ac, 5GHz, Channel 36, Maximum Internet Speed: 1 Gbps).
• BCMC has been tested with frequent switching between multiple access points and WPA2-protected wireless networks.
• BCMC has been tested with with map applications that rely on Wi-Fi to determine the current location.

 

>> Getting Started

 

Please carefully read the manual and update your bootloader configuration file properly.

Hi, @Austere.J

 

Broadcom Wi-Fi Chips with other Device ID they are not supported or simply have not been tested?

[jlrycm]

@Austere.J thank you so much for sharing this great development with the community. QQ: the repo documentation says that Apple Wireless Direct Link (AWDL) is not currently available on Wi-Fi cards supported by BCMC and at the end of the paragraph it says that “all Continuity features (e.g., AirDrop) that rely on AWDL are not working at this moment. You can use LocalSend as an alternative, or wait for OpenCore Legacy Patcher to add support for macOS Tahoe.” Just to clarify, is this limitation affecting all macOS versions you listed in the Readme as supported? 

[Austere.J]

Thank you all for your interest in this project.

That really depends on the type of chip. If it's a FullMAC chip, then theoretically, it can be supported.

I am interested in exploring other FullMAC chips, including those with 802.11ax support, so we don't have to stick with these old 802.11ac cards.

 

I know that a lot of folks in this community have BCM4360-based Wi-Fi cards, and I also have one myself.

I tested this card a year ago during the early development and found that it can be probed and configured just like 4350 and 43602.

However, I was not able to find firmware compatible with the card and the new driver, so I started looking at its Linux driver.

In Linux, 4360 is supported by the kernel module `bcma` instead of `brcmfmac` or `brcmsmac`, but I haven't yet figured out the relationship between `bcma` and other kernel subsystems.

This affects all three macOS versions I mentioned in the README, which is why I stated that BCMC is not yet suitable for use in production systems. (I am still using macOS Ventura on my workstation.) I am trying to bring AWDL back for these cards because I use AirDrop a lot, but I don't have an ETA.

@Austere.J thanks for the response.By the way, I have a Fenvi PCI-E WiFi Card BT4.0 for MacOS Windows 7/8/10/11 802.11a/g/n/ac PCI-E PCI Network Adapter which worked OOB and supported all Continuity features (based off MIMO Mac OS X natively Supported BCM4360 AC1200). Would I be possible to extract the firmware from the card itself?

Thanks for your offer, but unfortunately, the BCM4360 chip itself does not contain firmware; instead, the driver downloads the firmware to the chip and asks the chip to load the firmware.

 

As far as I know, there are two types of firmware for Broadcom Wi-Fi chips: one that is compatible with the proprietary WL driver (also known as broadcom-sta driver) and the other one that is compatible with the open-source brcmfmac/brcmsmac/bcmdhd driver. Apple stores WL firmwares as byte arrays for BCM4350, 4352 and 43602 inside the old AirPortBrcmNIC.kext, and if I remember it correctly, Apple uses the 4350 firmware for 4360 as well. These two types of firmware use different communication protocols, so the host driver must handle each type differently. (The 4360 chip seems quite capable of handling things in hardware, but I don't really know whether it can be classified as a FullMAC chip or not. Hmm, maybe I should try to load the 4350 firmware for 4360 in BCMC? 🧐)

Got it. I can try loading the 4350 firmware as well using the card I have and see what happens. Is it just following the instructions in your repo?

I might have to adjust the codebase to run this experiment. Stay tuned.

This seems promising. I have a 4360 device,

Although with your mention of IOMMUs and AppleVTD, will this work on AMD systems?

I don't have AMD processors, so I honestly don't know.

 

Is it possible to patch DMAR and/or toggle OpenCore's IOMMU-related settings (I remember there is an option like `DisableIOMapper`) for AMD builds?

I'm more than happy to test but where is LiluXL and DebugEnhancer64? I only know of the standard versions. 

 

Anyway I look forward to updates on this

I just tried to set up the 4360 chip with the 4350 firmware and found that the chip would not boot, so I guess the FullMAC firmware is chip-specific.

I have not yet finished the manual about those kexts for debugging. You can just ignore them for now.

@Austere.J I found this repo in the internet which has various BCM firmware files https://gitlab.com/kernel-firmware/linux-firmware/-/tree/main/brcm

 

can any of these work for you?

That's the firmware repository used by Linux distros; it's exactly where I got the firmware for 4350 and 43602. 🙃

The 4360 is proprietary so it’s hard to find (I imagine this is what you’ve found too). While searching the closest thing I have seen is users suggesting to leverage one of the Linux distro drivers like the Ubuntu bcmwl.

Update: I just took a glance at Linux's `brcmsmac` code.

it seems that BCM4360 is a SoftMAC chip, and `brcmsmac` uses the firmware `bcm43xx-0.fw`.

The chipset behind the Fenvi T919 is BCM94360CD, so it is not supported at the moment.

I suggest you stay with macOS Sequoia where OCLP is available.

Indeed. If you have heard of `b43`, you probably know the joy(TM) of dealing with Broadcom's Linux drivers.

Hence there’s no public bin file available for the 4360 😩

I will keep you all posted when I have good news about 4360.

 

Meanwhile, I want to focus on about the WPA 4-way handshake (which would allow us to use newer firmware) and other FullMAC chips (which would expand our available alternatives).

Looks like the kext is failing to start so firmware isn't an issue at this point I don't think. The kext is however loaded,

Here's an IOReg of the device if it helps,

 

 

I also tried pulling a trx firmware file from com.apple.DriverKit-AppleBCMWLAN.dext and changing it to a bin file.

What is the probability of this card working? I want to try according to the return I will receive from you. Thank You!

 

 

 

How can I copy the firmware files to the /usr/local/share/firmware/wifi/ location. Terminal said permission denied.

[gsxb]

followed the instructions to the letter and nothing, it won't turn on still no wifi can someone check my config for mistakes 

my hack boots fine however no wificonfig.plist

[Stefanalmare]

Any confirmation?

sudo is required. You've already made the directory. You can use Terminal or Finder to copy the firmware file to the location,

 

sudo cp /Path/to/Firmware.bin /usr/local/share/firmware/wifi/

Or with Finder press Shift-Command-G and enter /usr/local/share/firmware/wifi/ and then drag the firmware.bin file in. You'll need to enter your password to authorise the copy.
