The stock OS is ready out of the box with a full suite of integrated applications. While there are better versions of all of them, most are high quality. Though, I haven’t found a PDF reader better than Preview and Apple Notes is very hard to beat as a general note taking tool.
The base OS has color syncing. I was able to hook up a professional grade printer, have the OS automatically install the drivers, and produce color accurate prints using Preview. The system print dialog allowed me to fully configure the printer. No specialized tools required. There’s even an iOS app that can do the same thing in a more limited fashion.
Never had a driver issue or had to modify a configuration file to get hardware to work properly. (Have done GUI tweaks via defaults.)
When it comes to specialized applications, there are a lot of excellent applications written specifically for macOS. Some come with iOS apps. (1Password is high on my list.)
Due to the industries I work in, Microsoft Office is a hard requirement. Libre Office is not an option.
Time machine has no equal when it comes to backups and restoring to new hardware. I haven’t done a clean install since 2008. In two hours I can completely clone my current machine.
This is just a few of the many reasons I use macOS. Frankly, they are more important to me than openness of platform or deep control of my devices.
That does not mean I don’t appreciate Linux. I love Linux. There is nothing better for servers than Linux. I have older laptops loaded with Linux but they are a hobby for me.
Linux fills a very important place in the world. Frankly, the world needs open operating system and people who enjoy using it. But I have neither the time, expertise, or inclination to do so on my primary machine.
