Where can I get the BCM4364 brcmfac driver for Ubuntu 20.04?

"Firmware"="C-4364__s-B2/maui.trx",
"TxCap"="C-4364__s-B2/maui-X0.txcb",
"Regulatory"="C-4364__s-B2/maui-X0.clmb",
"NVRAM"="C-4364__s-B2/P-maui-X0_M-HRPN_V-u__m-7.5.txt"})

I tried wget https://packages.aunali1.com/apple/wifi-fw/18G2022/C-4364__s-B2/kauai.trx, but I got temporary failure in name resolution. Is this site still up?

Out of desperation, I tried using the MacOS BCM4364 driver on Ubuntu, but of course it didn't work. I'm getting Direct firmware load for brcm/brcmfmac4364-pcie... failed with error -2 .

This is what dmesg | grep brcmfmac shows immediately after a reboot:

[    4.690795] usbcore: registered new interface driver brcmfmac

I'm seeing a thread from last year on the exact same issue but there is no resolution: How can I activate wifi on BCM4364 using brcmfac driver & firmware? Anyone on that thread happen to figure this out?

Thanks!

Maybe install Ubuntu in VM on same computer, than if wifi adapter works in there, fetch the folder for firmware from there and plant it over to dual boot

My assumption is a protection at bootloader level, inactivating access to activate wifi adapter for some weird security reasons, as if dedicated only to Mac OS. Then any external usb wifi adapter works fine.
