Asahi Linux Adds Official Apple M3 Support at Last

M3 Support Lands in the Asahi Installer

Over the weekend of September 5 and 6, 2026, the Asahi Linux project merged support for Apple's M3 generation into its installer, and it is now official rather than experimental. Anyone running an M3, M3 Pro or M3 Max Mac can install Linux on it today. The one exclusion is the M3 Ultra in the Mac Studio, which remains unsupported.

• M3, M3 Pro and M3 Max are supported; the M3 Ultra is not
• Working now: Wi-Fi, Bluetooth, the webcam, internal microphones, USB up to the hardware limit of 10 Gb/s, and hardware-accelerated video decode including AV1
• Not working yet: 3D GPU acceleration, sleep, and the HDMI port on M3 MacBooks — the latter two both blocked on display coprocessor support
• Basic boot support is in mainline Linux, with further patches queued to bring upstream kernels to parity with Asahi's own builds

For a reverse-engineering project working without vendor documentation, the shape of that list is the story. Networking, audio input, camera and USB are the parts that take painstaking work and deliver nothing glamorous. Getting them to "almost everything works like it does on M1 and M2" is a substantial amount of quiet engineering.

Why the GPU Is Still the Holdout

The two conspicuous gaps — GPU acceleration and sleep — trace back to the same place. Apple Silicon routes display output through a display coprocessor, and until that is understood and driven properly on M3, the machine cannot power down its display pipeline for sleep, cannot drive HDMI on the laptops, and cannot get a fully performant 3D path.

The project is explicit that 3D acceleration on M3 is not yet performant or power efficient, which is a more useful statement than a simple "unsupported." It means the pieces exist but the result is not something you would want to run a compositor on all day. Desktop use is fine; a GPU-bound workload is not what this hardware is for under Linux right now.

Anyone who has followed ARM Linux enablement will recognize the pattern. Boot, storage and networking come first because everything else depends on them. Display and power management come last because they are the most tightly coupled to undocumented silicon behavior. The same sequence played out across the M1 and M2 generations.

What Does This Mean if You Own an M3 Mac?

If you have an M3 MacBook Air or MacBook Pro sitting on a shelf, it just became a very capable ARM Linux machine — with caveats you should know before you start.

• Good fit: development work, servers, self-hosting, terminal-heavy workflows, anything CPU-bound. The M3 cores are fast and the power efficiency survives the OS switch.
• Poor fit right now: GPU compute, gaming, external display work on a MacBook over HDMI, or anything where suspend-resume needs to be reliable.
• Expect movement: M3 support is currently gated behind Expert mode in the installer, but the project expects it to become the default before the next Fedora Asahi Remix beta.

That last point is worth watching, because "behind Expert mode" is the project's way of saying the support is real but the guardrails are not finished. It is not a warning to stay away; it is a warning to read before you click.

Why Open Hardware Enablement Keeps Mattering

There is a straightforward practical case for this work. Apple Silicon Macs are among the most power-efficient ARM machines you can buy, and a large number of them are two or three generations old and sitting unused. A functioning Linux port is the difference between a drawer and a home server. Readers who have been following our mini PC and small-computing coverage will recognize the theme — we made a similar point about the value of efficient ARM desktops when we looked at local LLM performance on the Mac mini M6, and the memory-capacity question in how much RAM you need for a local LLM applies just as much here.

The broader point is about optionality. Hardware that only ever runs one operating system has a lifespan set by that vendor's support calendar. Hardware with a credible second OS has a lifespan set by the silicon. The Asahi project has now extended that second option across three generations of Apple Silicon, entirely through public reverse engineering, and the M3 work arriving with Wi-Fi, camera and AV1 decode already functional says the process is getting faster with practice.
