One of the reasons I like macOS has to do with its Unix underpinnings. From the pre-installed Terminal application, I can efficiently perform administrative tasks, edit text files with Vim, connect to other systems via SSH, and so on and so forth. I admit there are times macOS almost feels like a BSD or a Linux system to me – but with a sleek GUI on top. Of course, I very well know that macOS is neither BSD nor Linux.
