Hey thanks for your time in advance. I'm trying to install debian bookworm 12.4 on MacbookAir7,2 that doesn't have an ethernet port and the installer doesn't recognize it's wifi card and what drivers it needs for the card to work. From searching the web I found that it uses Broadcom BCM 4360 wireless network adapter and requires broadcom-sda-dkms firmware drivers to function. The installer doesn't detect the wifi card and none of the drivers from the select list work and when I use 2nd bootable USB formatted as FAT32 with broadcom-sda-dkms firmware drivers saved to root and firmware folder it doesn't accept drivers and gives out error "ethernet card not found" I've looked through entire debian wiki and other wikis and forums like arch wiki and found no answers anywhere. I have successfully installed ubuntu on this macbook air and it works just fine with the wifi card. Could you please shed some light on how I can possibly install debian on this macbook air.
Some other things that I've tried that didn't work.
Every available driver from the install list.
Older non-free debian version 11.8.0 because I thought it would have drivers but it didn't work either.
Using command like during installation for extra option to load drivers off USB. (this command doesn't seem to work on bookwork 12.4)

Using rtl8812au-5.2.20 firmware drivers
Ripping out firmware drivers from ubuntu install that works fine with this wifi card and putting it on same USB bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu10~22.04.1_amd64
