As someone who had to help coworkers with Windows, Mac and Linux problems one of the main problems of macOS is the fact that you have to use the clumsy GUI for so many things and that the Unix-like underpinnings are badly maintained and outdated so many systems have several versions of the same tool installed in various locations (OS-, Homebrew-, MacPorts- or whatever other package manager of the day versions).
Also to advocate for a specific tab size while also advocating for hard tabs is nonsense. The one flimsy claim to usefulness tabs have is that different people can use different tab sizes and all at the low, low cost of everyone having five times more work to use tabs for indentations and spaces for alignment and thus having to use visual whitespace of some kind.
