I was able to install Ubuntu 20.04 on a 2018 MacMini using this post. The main remaining issue is that Ubuntu cannot find the wifi adapter. The pci.id (see below) is different from any of the ones listed in this post where it was suggested to create a new post on askubuntu.com for any unlisted pci.id. Thanks in advance for any suggestions you might have

lspci -vnn | grep Network
03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4364 802.11ac Wireless Network Adapter [14e4:4464] (rev 03)
    Subsystem: Apple Inc. BCM4364 802.11ac Wireless Network Adapter [106b:07bf]

  • Thanks. The post you linked is the same one that lead me to create this new post actually. The issue is that the pci.id (14e4:4464) is different from any of the ones listed there. I tries all the suggestions that I could find and was not able to eve get the wifi adapter to be recognized by Ubuntu 20.04 – Vincent Oct 19 '20 at 01:59
