Hello. I am trying to use elementary on my macbook pro, but i won't display wifi unless i plug in usb wifi dongle. So, the drivers are missing i suppose. I had this issue before and it was solved with a system update. Now how can i fix and enjoy elementary os?

    sudo apt-get install firmware-b43-installer

  • This did not work for me and my 15" Macbook Pro 2013. I had a bad ethernet cord, so solving this took 10x as long. Running the Updates in AppCenter seems to be working. Click on the Broadcom Driver. Yes it worked after reboot. I have WiFi icon showing. Get Wired Connection and Run the Updates FIRST. Then install the bcmwl-kernel-source Drivers (you have to click on them in AppCenter). For the 2013 Macbook Pro, the secret is getting the Thunderbolt to RJ45 (Ethernet) dongle. Even after I connected it, I had no ethernet device name after [ip a]. I had to test on another machine to find out my et Nov 11, 2020 at 19:11
