Unity Case sensitive file system on macOS
Although MacOS has options to work on Case Sensitive disks, most of its applications [mainly 3rd party apps] do not work well on Case Sensitive disks, for historical reasons. Yet this is a future step to next versions to correctly work on Case Sensitive.

Please use any Case Insensitive disk/share to be able to not run into troubles.

Eg:
Many applications can't differentiate thisfile.txt from thisFile.txt so if you have both on any case sensitive disk, the App may get into trouble. Others may work well. It's like lottery.

MacOS [operating system] works relatively well on case sensitive disk, but 3rd party apps may not work so well.
