I just don’t think this is what, like, nine-year-olds are looking for in a computer.
In any case, at least it’s good that they’re starting with macOS over Windows! Puts them on a good path to understanding that POSIX is the One True Paradigm and therefore makes them much more likely to compile their own kernel in the future.
My curiosity for all things computer related was boundless, but I eventually tinkered with Linux but only because I’d had been exposed to a *nix style command line from the comfort of an OS X desktop first.
By then I had started messing around with code but had only built toys and extremely basic tools and would’ve been lucky to write a moderately functional desktop program using high level libraries (which didn’t happen for several more years).
Writing drivers or poking around in kernel code was so far beyond the scope of capabilities at that point that you would’ve had better luck teaching your dog how to knit. I don’t think I could’ve had any chance at doing these things until at least my mid 20s.
I get the feeling a whole bunch of teenagers have written drivers to cheat in Fortnite/whatever other game - with that being said, probably not at 9 years old.
