Maybe I am being over cynical by isn't this a huge waste of time given that Apple can "pull the plug" at any time? They want to control everything that runs on their chips so why bother?

The way they've implemented it suggests that it's intended for there to be support to boot other things.

Going back on it and locking it down could end in another lawsuit like the OtherOS removal from the PS3 (Which ended in $65 settlement payments it seems)

With that attitude, no one would have ever started trying to write and run their own kernel called Freax on a PC...

This is very anecdotal but every single laptop I have bought in the last 10 years (4) worked perfectly out-of-the box with either Linux Mint or Ubuntu (which are the same on the inside). I only vaguely remember once I had to change some conf file for my trackpad to work after a dist update but that was it. Not sure why everyone in this thread is so hesitant about Linux on a laptop? It literally just works (tm) for me…

Same here, although I have been mainly on Windows for the past 5 years because of other reasons.

If I didn't use my computer for music production I'd have no problem going Linux only.

It's never a waste of time to try and assert more control over the hardware you own. Apple kept the iPhone fully locked down since day 1, but that didn't deter a massive jailbreaking community. Heck there were app stores on iPhone even before Apple could launch its own.

The short answer is that this is a different beast. Much of the hardware in Macs before the M1 was commodity hardware. Now it is all bespoke and undocumented. This is a big undertaking.

Apple has publicly stated their intent to permit users to run other operating systems on Apple silicon, and has provided various mechanisms for them to do so in a first-class way (still supporting secure boot, for instance). Of course, they haven't gone as far as many of use would like - marcan has had to do a lot of reverse engineering of stuff they could have just released the docs for, and it's always possible the…

Can you link to the public statement? Would greatly appreciate that, thanks!

Somewhat related: I'm super curious if M1's advantages would melt away if Intel simply fabbed their current designs on TSMC's 5nm process, to have a level playing field between Intel and Apple's chip designers.

> if Intel simply fabbed their current designs on TSMC's 5nm process I think that ‘simply’ is the wrong word.

This, porting an architecture to another process is a multi-year process. In a Reddit AMA a week and a half ago they mentioned that the Rocket Lake backport took 2 years (from 10nm -> 14nm) [1]. That's quite a quick schedule and also on a very mature process.

"The project final concept closed in Q1 2019 and we are launching today, so your estimate is right. Took us 2 years for RKL"

Macbooks make one of the good linux laptops (the ones that have support like older retina macbooks). And the truth is Macbook Air is one of the handful ARM consumer laptops you can easily buy right now even though ARM is the superior everyday computing platform to x86. What a weird time in personal computers.

Don’t equate ARM with Apple silicon. If the M1 was an x86 cpu it’d blow Intel out of the water exactly the same way it did now.

The M1 has greater instruction-level parallelism. That is what allows the M1 to run at a lower clock that Intel, but still run faster.

It really depends on what you buy / how recent it is. If you buy a just-released new model (that's not just a trivial bump in specs from the previous version), you will likely run into issues.

But you're right - the experience is way better than a decade ago and these days I'd expect anything that's been on the shelf of a local office store to work just fine.
