They had the opportunity to do this when introducing the M-series Macs, because under the hood those work very similarly to iPhones and iPads. They could've done a direct copy-paste from the iDevice boot process and called it a day, but they didn't… they went out of their way to develop support for booting third-party operating systems, complete with a path for painless long term support with the flexibility of allowing the OS to choose which version of firmware to run on the hardware (so Apple can deploy compatibility breaking firmware updates for use with macOS without stepping on the toes of e.g. Asahi Linux).

In macOS itself the main goal is to get third parties out of the kernel to the greatest extent possible, which makes perfect sense. Third parties, ideally, should be operating solely in userland, because otherwise you get pointlessly insecure nonsense like cloud file storage apps installing kernel extensions (like Dropbox used to on macOS).

No, they didn't because a Mac computer that is fully locked like the iDevices wouldn't have been popular and would have meant a lot of bad publicity for the M1 mac desktops. Apple Silicon M1 / M2 macs can only run crippled versions of other OSes and macOS is being slowly converted to be more and more like ios. It's the Boiling Frog strategy - https://en.wikipedia.org/wiki/Boiling_frog - to ensure that they don't scare away their users. With soldered harware, no viable alternate OSes, and taking away developer options from macOS, all Apple Silicon M1/M2 macs are now just a few more steps away from becoming like the iDevices.

What do you mean by “crippled”? As far as I can tell the only limiting factor on the capabilities of other OSes on Apple Silicon is the state of hardware support, which is marching forward at a brisk pace and it doesn’t look like there’s anything stopping third parties from fully leveraging the capabilities of that hardware.

Approximately nobody would have passed on a Mac because it could not boot Windows or Linux. This has been more or less the state of Macs since the release of the first M1 devices, and they sell rather well. There is demonstrably quite a lot of interest for these devices running macOS.

How so? What do they do to cripple other OSes?

Quoting Wikipedia for common phrases does not make you more credible. Again, people have been saying that for more than a decade. It is not inconceivable that it could happen in the future, but then anything could happen in the future. And in the meantime you still sound like a broken clock.

> to ensure that they don't scare away their users.

The whole history of iOS demonstrates the opposite. As said in the parent comment. They’ve had opportunities to actually go to that direction. Nobody was expecting third-party OS support.
