Download DC Studio

Apple Silicon Mac, macOS 14 Sonoma or later. Free, GPLv3, Stockfish 18 inside.

Latest release on GitHub

Download DC-Studio-<version>-arm64.dmg, open it, drag DC Studio into Applications. Every release carries a .sha256 beside the DMG.

First launch

The build is signed but not notarized, so macOS blocks the first launch with Apple could not verify "DC Studio" is free of malware…. That dialog offers no way to continue — dismiss it (don't let it move the app to the Trash), then either:

xattr -dr com.apple.quarantine "/Applications/DC Studio.app"

or open System Settings ▸ Privacy & Security and click Open Anyway next to the message about DC Studio. Once, per download.

Notarization is on the list. Until then the source is on GitHub and the DMG's checksum is published with each release, which is what "verified" would otherwise tell you.

Building it yourself

The Command Line Tools are enough — no Xcode: cargo test for the Rust core, swift run StudioApp for the app. See the README.
