macOS Runners (M4 Pro)
Apple Silicon (M4 Pro) macOS GitHub Actions runners, with four sizes, macOS 15 and 26 images, and monthly image refreshes.
Tenki macOS Runners run on Apple Silicon M4 Pro hardware in four sizes, from 2 to 8 vCPU. Standard runners are available with macOS 15 Sequoia or macOS 26 Tahoe. Every job gets an ephemeral VM that is destroyed at job end; see Security & Isolation.
macOS runners are available on all plans. Typical workloads: iOS builds and XCTest/XCUITest suites, macOS app builds and notarisation, React Native / Flutter / Unity iOS builds, and fastlane release pipelines with code signing.
Sizes
Specifications for each size are on Runner Sizes & Labels. Current rates are on the Pricing page.
Standard images
Choose the operating system and default Xcode family with the runs-on label:
tenki-macos-15-{mini,small,medium,large}runs macOS 15 Sequoia with Xcode 16 by default.tenki-macos-26-{mini,small,medium,large}runs macOS 26 Tahoe with Xcode 26 by default.
Each image includes multiple Xcode releases and simulator runtimes. See GitHub's official software manifests for the current macOS 15 ARM64 and macOS 26 ARM64 toolchains.
Tenki mirrors these official GitHub-hosted software lists and refreshes its standard images once per month. Exact tool and patch versions can change with each monthly refresh.
Concurrency
The Team plan includes 4 concurrent macOS jobs by default; higher macOS concurrency is available on request. See Limits & Concurrency.
