Linux on Apple Silicon with Alyssa Rosenzweig [audio]

Original Article ↗ Hacker News Discussion ↗

Efforts to run Linux natively on Apple Silicon laptops, led by projects like Asahi Linux, are praised as impressive feats of reverse engineering that unlock Apple’s highly efficient ARM hardware for open-source use. Commenters weigh the appeal of Apple’s performance, battery life and build quality against the risks of relying on a small team to support a closed, rapidly evolving platform, noting practical issues such as incomplete driver support, Wayland quirks, and hardware safety mechanisms that must be painstakingly replicated. Many see the work as philosophically important for user freedom and device longevity, while others argue that buying more open x86 or ARM hardware is a better way to support the broader Linux ecosystem.

Motivations for Linux on Apple Silicon

  • Desire to run Linux natively on very high‑quality, efficient ARM laptops with excellent performance, build quality, battery life, and thermals.
  • Some like the hardware but dislike macOS or want long‑term support after Apple ends OS updates.
  • Seen as a pure “hacker spirit” project: technically inspiring, educational, and a portfolio piece.
  • Viewed as reducing e‑waste by keeping older Macs useful.

Critiques and Ethical Concerns

  • Some see the reverse‑engineering effort as a waste of scarce talent and time, indirectly enriching a closed vendor.
  • Worry about depending on a tiny volunteer team versus a trillion‑dollar company that could break things with new chips or firmware.
  • Argument that buying Apple hardware supports a hostile/walled‑garden business model; others frame it as simply “voting with your wallet.”

Apple’s Openness vs Lockdown

  • Acknowledgment that Apple deliberately designed a boot chain that can securely run unsigned OSes on Macs, unlike iOS devices.
  • Counterpoint: true support would include public docs and drivers; bootloader openness alone is limited.
  • Debate whether this is goodwill, antitrust preemption, internal champions, or just preserving the Mac’s developer market.

Technical Challenges and Reverse Engineering

  • GPU, speakers, and (future) HDR displays are hard: safety‑critical behavior (e.g., speaker “temperature” models in userspace daemons) must be replicated without blowing hardware.
  • Apple’s fast chip cadence and lack of docs means repeated reverse engineering per generation.
  • Comparisons with x86 and Nvidia: historically lots of reverse‑engineered drivers, but today many vendors contribute directly to Linux.

User Experiences with Asahi Linux

  • Some report Asahi as a daily‑driver success, faster than macOS for development and stable enough.
  • Others report many bugs: Wayland/KDE quirks, app crashes, display issues, flaky third‑party drivers (e.g., DisplayLink), missing hardware features.
  • General consensus: impressive early progress, but still not “it just works” for all use cases.

Hardware Competition and Alternatives

  • Debate over how far Apple’s performance‑per‑watt lead still extends versus modern AMD/Intel/Qualcomm.
  • Some prefer open‑friendlier x86/ARM laptops (Framework, ThinkPad, Chromebooks) and VM‑based Linux on Macs.
  • Battery‑life advantages (e.g., “all‑day” use) are highly valued by some, seen as overhyped by others.

Community, Funding, and Social Dynamics

  • Calls for crowdfunding to accelerate development.
  • Some recall earlier hostility or off‑topic identity debates around the project, leading to Asahi blocking HN referrers for a time.
