> Why don't sed, awk, grep, etc.. all the Linux things work quite right? I need to add something else on macOS to get them to work like they did on Linux.
If you mean how they work, like command line arguments and such (and not just speed), that's because macOS is based on BSD and thus using the BSD and not GNU versions. That's not really a "not right" thing, it's just different, and would be the same if you used any other BSD like OpenBSD, FreeBSD, etc.
