I expect that running alternate OSs on an ARM Mac to be about as easy as they are on an iOS device. Which is to say... not easy. Apple has been working to close holes in the secure boot for many years.

The question of course is... why bother? I kind of get it as far as the laptops go, because of the hardware design. Though I think that gap has closed considerably in recent years and you can get a decent laptop that runs Windows or Linux. Though in the Linux case, support for features like suspend / resume and such tend to be spotty.

For desktop hardware, I don't see the value proposition for running an alternate OS.

Ultimately it's the users device and the user will do what they want with it. Locking bootloaders is just security theatre.

if someone wants to run Linux/otherOS on their computer, they should be allowed to do so.

It’s not just security theater: ask how many people will use Linux intentionally versus how many will be compromised by malware which uses the same technique for persistence?

You might be able to do something like encrypting the macOS partitions with a key which won’t be given to a non-trusted boot path but that’s a lot of work and new security risk for something which almost nobody will use since most people are buying Macs for the software and very few people have needs which can’t be satisfied by running Linux under the built-in hypervisor.

Suspend and resume has been stable for 10 years on linux.

There is a clear value proposition for taking an old mac and installing Linux. No value for Apple, they want you to landfill the laptop and buy a new one.

They don't want you to landfill it, they want to buy it back for half-market-value so they can resell it or reuse parts and metals. With cheap repairs you'd get your MBP fixed for $300 instead of sell it back to Apple for $300. With upgradability you'd max out ram and storage and get additional years out of a computer that maybe only shipped with 128gb of storage and 8gb of ram because you didn't have a spare $2000 for soldered upgrades on day zero. It all just pushes and guides you back to Apple to return the machine you quasi-leased for a slight discount on the next.

Quasi-leased? My Macs have always lasted far longer than my Windows PCs, if that’s a lease it’s the lowest cost one ever.

If you're looking at pre-2016 hardware sure, we can look back and see this stuff still ticking along very nicely and setting new expectations on longevity. Anything since is stuck with soldered storage and whatever ram unless you upgrade the entire machine. Anything with a butterfly keyboard is dependent on a free keyboard replacement program that ends soon for the earliest models. OLED degrades over time so there's a TBD lifespan on touch bar screens. The iMacs and Mac Pro might last forever on the hardware side, but if Apple only needs two years to transition to their own hardware they'll have no software support long before the hardware is useless. None of this is going to last like the previous generation.

> Suspend and resume has been stable for 10 years on linux.

I should have been more clear. What I meant was that buying a mainstream laptop with Windows pre-installed, and then putting Linux on it. In that case, things like suspend / resume may or may not work.

Sure, one of those rare Linux-specific laptops (System 76, Dell, etc.) will see dramatically better hardware support.

Not on Macs it hasn't. On the late 2013 it definitely didn't work. Along with a bunch of other things. Extremely unstable Linux machine. I assume all Mac laptops are the same. Except for the last three years. Can't even install Linux on those afaik.

I think 95% of people running an alternate OS on a Mac computer are doing it for dual booting Windows and video games.
