Defaults to case insensitive
So this has bit me twice in the last week. Once for work and once on personal projects. When my mac updated to use APFS a few releases ago. It chose the most compatible option and is case-insensitive. Which is wrong for any one developing code and deploying on linux or unix based case sensitive systems.
I can change this, but I would have to reformat and rebuild my system. So I'll likely not change it till I get a new machine.
