For a lot of normal people, Mac is what you buy if you want to work with your computer, but it is not what you buy if you want to work on your computer.

Do you work with your screwdriver or on your screwdriver?

With my screwdriver.

Unless you're a blacksmith who makes his own drivers or a wordworker who makes her own handles, the same is true for you.

I have a custom wrench in my toolbox. I forget what the issue was, but 15 years ago I think I was working on someones skis or something? Anyway, I had to cut the handle in half and welded it back together at a different angle.

Quick and easy hack job. I'm not a machinist, mechanic, or metal working professional of any sort. But I had access to a shop at the time, so I was able to take my tools that were almost what I needed and turned them into exactly what I needed.

Literally no biggie. I feel like I'm hanging out in the kind of crowd that unironically asks "why do you change your oil yourself?"

That's completely orthogonal to Apple's take. They talk about how much your development efforts will speed up, your creative production. So on, so forth.

Not "it's to be an unadventurous consumer of product".

Who they market their users are != who their users actually are.

Obviously all the marketing will focus on creative uses because it makes it a lot easier to sell to people on a 1500$ machine. The truth is 95% percent of people are using their computers as glorified web browsers and the computers are built to do that extremely well.
