I have two very nice MBP systems (late 2018 and early 2019) that I would like to run Ubuntu on, solo boot.
Logging my efforts and contributing to Apple Hardware Users is a no brainer. The effort will go faster if I can find like-minded developers to join me or lead me.
Fwiw, I was able to follow one guide with success but have not been able to repeat it so I know it can be done.
Left to my own devices, I will continue following whatever leads I find on the Net until I get to yes or I understand why it cannot be done ... yet.
