In deeply saddens me to think that there is a developer who has not installed gnutils and put them earlier in the PATH.
The remaining differences are related more to systems stuff - managing daemons with launchd for example. These aren't really a distraction day-to-day.
It’s a computer. I can make a computer go beep if I want, that is not the issue.
The fact that someone who didn’t grow up at the time when open source was an idealistic concept instead of free support to corporations needs to learn about the gnutils and how to install them with homebrew is what makes me sad.
Why do we seriously not have a command-line package manager on macOS yet? Windows has one by now. It’s just sad to me that you need a manual checklist of post-setup steps to turn a Mac into a useful machine for software development.
It really is that simple. No different from a BSD or even a non-GNU (busybox, etc.) Linux distribution. If you like GNU tools, use them.
