GitHub has launched a public beta for its Apple silicon-powered M1 macOS larger runner for GitHub Actions, aimed at enhancing performance for developers by utilizing the M1 processor's on-chip GPU capabilities. This runner, equipped with a 6-core CPU, 8-core GPU, 14 GB of RAM, and 14 GB of storage, offers significant build time reductions—up to 80% compared to existing Intel runners. The GitHub mobile iOS team has already experienced a 44% improvement in build times, with UI tests and code compilation seeing enhancements of 55% and 51%, respectively. Transitioning to the M1 runner requires minor workflow updates, but snapshot tests necessitate re-recording due to differences in UI rendering between M1 and Intel Macs. The runner facilitates faster App Store reviews and is available to all developers without prior sign-up, with new pricing set at $0.16/minute for XL and $0.12/minute for large. Future progress can be tracked via GitHub's roadmap, with macOS 14 anticipated later this year.
