Linux on Apple Silicon with Alyssa Rosenzweig [audio]

Original Article ↗ Hacker News Discussion ↗

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.
