Have exact same WiFi module.
Decided to throw EOS on my old Macbook I use 2-3 times a year for travelling abroad. Probably a bad idea as you can imagine the backlog of updates everytime I take it out of storage and abroad.
- ID: MacBook Pro12,1
- Model: A1502 (EMC 2835)
- Year: Early 2015
- Wifi: Broadcom BCM43602
- Wired: Broadcom BCM57762
Fresh EOS online install - To get the Wifi working from Arch wiki I made a /etc/modprobe.d/no_bmca.conf file and added line blacklist bmca. Then removed broadcom-wl package. So then brcmfmac open source driver will be used without conflict.
Rebooted and Wifi all working
