Darling Development Update – Q4 2026

By · Published by Everything Blog

In short

The open-source compatibility layer Darling is officially adopting AI-assisted contributions alongside new ARM64 capabilities. This structural shift follows major successes in experimental forks, such as running League of Legends on Linux. While automated tools are permitted, project maintainers are enforcing strict clean-room reverse engineering standards and requiring human accountability for all submitted code. Over the next two months, maintainers plan to merge work from these external forks back into the main repository using agent-driven workflows.

  • Contributors using AI assistance remain personally accountable for explaining their code…: Contributors using AI assistance remain personally accountable for explaining their code and answering maintainer inquiries without automated bots.
  • Where legally permissible, disassembly may only inform high-level behavioral descriptions…: Where legally permissible, disassembly may only inform high-level behavioral descriptions that an isolated AI agent uses to write code.

It's been a while since our last progress report, and a lot has changed. This update covers the biggest shifts in the project: our new policy on AI-assisted contributions, initial ARM64 support, and what we plan to work on next.

Our AI Policy

The biggest change in the project this year is not a feature, but a policy: we have adopted rules for AI-assisted contributions. We know this is a divisive topic that many open source projects are debating right now, and the concern about low-quality "slop" is a fair one. But in the hands of people who know the project's internals, an LLM can be a very powerful tool.

Developing Darling has always been a lot of fun, but it was also hard to see the light at the end of the tunnel. Let's face it: Apple is a huge company with many engineers shipping new features all the time, and a small group of volunteers is no match for that capacity. I started Darling in 2012, and until recently very few real-world macOS applications actually ran on it.
