alt Hacker News> when they can just share a pdf.
I assume your question was in good faith, but the information needed to support an entire platform like this is not as simple as sharing a PDF. I’ve spent parts of my career working on much simpler platforms than an entire Apple laptop where we would have to work through 10,000 page PDFs documenting registers and even that was not enough to get the full picture of the system. You have to work through provided code samples and then eventually get the vendor’s engineers to look into problems that couldn’t be resolved through the documentation, where they would go look into the other teams and their sources to discover the answer.
The market for people who want to install Linux on a Mac laptop is very tiny. The honest answer is that it’s not worth the huge effort investment needed to document an entire platform for public consumption.
I don’t think many people realize how easily Apple could have locked down the laptop to be able to not run any alternate OS at all and the number of lost sales would be so negligibly small as to not matter. They chose to leave it open.

If you’ve ever tried to lock down a mac and dealt with the 100s of system services, you’d know why. I like the hardware and base os, but I have no idea what those services are doing.
Many are undocumented. A lot can’t be disabled, even with SIP disabled. And, they’re chatty and persistent in trying to communicate out. You can kind of disable communication of TCP/IP but they’ll find alternatives - like low power bluetooth or even lower in the network stack.
I only use my mac for development. I’m a simple man and don’t need all the bloat and hidden behavior. Plus, I always feel like I’m one automatic update away from it becoming unusable.

I suspect there would be an element of induced demand here. IMO the MacBook range are the only laptops on the market worth buying - but not having support for gaming (or at least, hilariously bad support for a limited range of games) is compelling enough reason to install Linux for a large portion of users (filling the void left behind by the widely adopted Bootcamp).

Yeah, GPU ISA, controllers, power management, NPU, and who knows what else. I still believe that companies should be compelled by regulators to offer documentation and support necessary to write drivers as I believe it is part of the "right to repair" (M1 will lose support in 2 years, it's still a great platform).

I _really_ wonder on this point. It's so uncharacteristic of Apple. Were they concerned about potential anti-competitive lawsuits and maliciously did the bare minimum to avoid them? "It's technically open hardware, but good luck figuring out how it works"
This is nonsense. Chinese vendors like Rockchip and Allwinner provide fairly halfassed docs at times, but they try. It's housnads of pages, total, sure. But even this along with public code samples allows to create almost perfectly FOSS supported implementations for their HW. And it's a complex HW similar to what Apple has. I've worked with all kinds of just annoyingly incomplete and badly written datasheets, and if you put some work into it having at least something helps tremendously, even if the manufacturer ignores you completely and you have no field engineer access, and just throws incomplete crap over the public fence.
No docs is clear statement Apple hates FOSS. "how easily Apple could have locked down the laptop" argument is very weak considering that only consumer platforms that engage in a complete lockdown are maybe some gaming consoles, and those are basically appliances and not a general computing machines.

It's only going to grow every year as apple stops releasing OS updates for perfectly functioning hardware.
> The market for people who want to install Linux on a Mac laptop is very tiny.
Right now, yes. But Linux support is like freedom of speech in a dictatorship.
Everyone makes fun of it and says it's useless but fundamentally the powers that be are deathly afraid of it ever turning the tide.

Oh please - Apple provided a full suite of Bootcamp drivers for their hardware just a couple of years ago, not locking you out is not a big heroic move you're trying to picture here.
You describe an exhaustive documention, but some documentation would already be better than none. Perfect is enemy of good, as your comment illustrates.
