Rosetta 2 for Linux is my favourite feature of Mac at the moment. I've been working on a project for many years that had a hard dependency on a library that only compiled on amd64 architecture. So for the longest time I was dual wielding a Mac and Framework laptop. I really hated switching between the two and moreso using Linux on my Framework; just felt like a bleh experience. When Rosetta 2 for Linux came around, I immediately started using it and was fully productive developing on our Intel only projects. I don't see any perceivable speed loss, t hough we had to adjust some sleeps for a few concurrency/threading tests to accommodate Rosetta.

Apple really did not have to make Rosetta 2 available for Linux. If they hadn't, it wouldn't even register a blip on the users / market share of Macs/MacOS. But it's just one of those hidden gems of the OS, and going by this article they haven't stopped improving on it.

> Apple really did not have to make Rosetta 2 available for Linux.

The kinda did - offering good Linux dev environments is now a fairly big feature for both of the major Desktop OS's nowadays.

Most Linux dev environments do not need to be tied down to Intel. In fact it is more performant and efficient if you're working on ARM native on Linux. It was already a good Linux dev env before Rosetta 2 was on the scene, they just enabled more use cases with Rosetta 2.

I also do not see much need for Rosetta support for Linux as arm64 Linux works fine for most of my use cases. However it is definitely better to have Rosetta support than not having it.

This unfortunately only holds when working purely on open source. Shipped binaries for aarch64 are still not super common for proprietary things within the enterprise space.

And the only way Desktop Linux will actually grow beyond the usual 1%.

I don't think it counts as Desktop Linux if its running in a CLI-only VM targeted at developers on a different host OS.

It may not count, but that is what you will get in most shopping malls as "Desktop Linux" for common folks.

Even if you add Chromebooks as third option, Crostini runs in a VM just like WSL 2, and still has quite a few integration issues to this day.

Netbooks could have been it, but first they were torpedoed with Microsoft's clever move to make Windows XP licenses free for those OEMs, followed by the introduction and wide adoptions of tablets.

OEMs like Tuxedo or System 76 will remain a niche compared to how many people end up running GNU/Linux on desktop VMs.

Before WSL I had long moved away from dual boot into VMWare Workstation.

It works on GUI VMs as well. UTM makes it very easy to use.

I agree it still doesn't help much with the desktop Linux bit though. :D

WSL runs GUIs too. And so did things like vmware and virtualbox for many years before it.

Which, to be fair, is something like tens of millions of Linux desktops. Several orders of magnitude less than the other types of Linux-powered computers out there though.

No one cares what the relative numbers are. As long as there is enough absolute users to justify the effort.

Yeah, but those other ones don't run GNU/Linux for normies, which was the whole premise of The Year of Linux Desktop meme started on the last century.

so 6%+ then :)

May you explain how you use it practically? How do you get it working in your choice of Linux?

I do it all via docker. I execute `docker --platform linux/amd64 <run|build>` and it uses Rosetta 2 for Linux in the VM (colima sets the rest up automatically).

Curious about your setup, especially regarding GUI support: are you running Rosetta in the GUI VM? I haven't tried Rosetta yet myself, and I'm considering options for a stable Linux VM (not frequently creating and removing VMs). I'd appreciate any insight!

Also, reading through this thread has given me an "aha" moment about the under-the-radar innovations Apple is building. Many people criticize Apple without understanding these aspects, and I’m not an Apple fanboy. I had similar realizations with Microsoft’s .NET, which I still believe is incredible underrated.

Lastly, how does running the Linux VM impact battery management efficiency?

I only run Rosetta 2 for Linux via `docker --platform linux/amd64 <run|build>` which triggers the rosetta helper in the underlying docker VM to do the right thing. I use colima for a docker VM which sets up Rosetta 2 automatically.

I don't know anything about GUI use; I don't run Linux for GUI stuff.

Linux VM affects battery proportional to how much you use it. For example when I build our projects that take 12 minutes running across all cores, I'm using the laptop at 100%. When I'm not using docker, the VM is idle, and therefore doesn't really impact battery whatsoever.

May I ask what felt wrong with Linux on the Framework ?

I usually post my opinion on every framework thread that pops up just to add a bit of diversity, you can see my most recent post here: https://news.ycombinator.com/item?id=41551909#41554801
