I am using my MacBook Pro Retina 13" early 2015 with High Sierra on a daily basis. I realized that I am using it like a normal Linux computer.
Nothing special or related to MacOSX. I installed Kubuntu 17.10, and the result is very good. I have a fully functionning machine with all the tools I need with the fun of using open source based softwares.
I can benefit from the Retina display resolution with a huge desktop to watch Netflix, code something and debug in the browser.
