## Why The public Codex release workflow needs to sign and notarize macOS binaries and DMGs without placing the Developer ID private key in GitHub. This moves the private-key operation behind the protected `codesigning` environment and uses GitHub OIDC with Azure Key Vault PKCS#11, while preserving the existing external `build_unsigned` / `promote_signed` fallback. ## What changed - Add a reusable AKV PKCS11 setup action that authenticates to Azure with OIDC, downloads pinned signing tools, verifies their SHA-256 digests, and loads the public signing certificate from Key Vault. - Replace the legacy macOS signing action with scripts that support AKV-backed `rcodesign`, notarize signed binaries and DMGs, and staple DMG notarization tickets. - Restructure `rust-release.yml` so macOS builds produce unsigned artifacts first, protected jobs perform signing and notarization, macOS runners package and verify the results, and release publishing waits for verified artifacts. - Preserve the manual external-signing handoff flow and make manual-mode conditions explicit. - Move the Codex entitlements file alongside the signing scripts and update CODEOWNERS for the new signing surfaces. ## Verification - [Live protected signing workflow run](https://github.com/openai/codex/actions/runs/26903610631) completed successfully for both macOS architectures, including binary signing/notarization, DMG signing/notarization, and final artifact verification. - Downloaded both signed DMGs and independently verified their checksums and strict signatures. - Confirmed `xcrun stapler validate` succeeds and Gatekeeper accepts both DMGs as `Notarized Developer ID`. - Mounted both DMGs and confirmed the contained `codex` and `codex-responses-api-proxy` binaries have valid Developer ID signatures for the expected architectures. --------- Co-authored-by: shijie-openai <shijie.rao@openai.com>
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
