Reproducible scripts to rebuild the Codex desktop app for Intel macOS (x86_64).

This repo does not distribute a prebuilt app. It automates rebuilding from your local install.

git clone https://github.com/ry2009/codex-intel-mac.git
cd codex-intel-mac
./scripts/quickstart.sh --open

That builds required Intel artifacts, repackages Codex.app, signs it ad-hoc, and writes:

• /tmp/Codex-Intel.app

1. Builds Intel-native dependencies for Electron 40:
   • better_sqlite3.node
   • pty.node
   • spawn-helper
2. Replaces arm64 runtime/helpers/frameworks with Electron x64 equivalents.
3. Bundles an Intel codex CLI binary when auto-detected.
4. Removes sparkle.node by default (auto-update disabled, app still launches).
5. Ad-hoc signs the rebuilt app.

• macOS Intel (x86_64)
• Node.js + npm + npx in PATH
• Xcode command line tools installed
• Existing /Applications/Codex.app (arm64 release)
• Network access (for npm dependencies)

End-to-end flow:

./scripts/quickstart.sh --open

Useful options:

./scripts/quickstart.sh \
 --source-app /Applications/Codex.app \
 --output-app /tmp/Codex-Intel.app \
 --workdir /tmp/codex-intel-build \
 --open

Build Intel artifacts only:

./scripts/prepare-artifacts.sh --workdir /tmp/codex-intel-build

This writes /tmp/codex-intel-build/artifact-paths.env.

Repackage only:

./scripts/repackage-codex-intel.sh \
 --source-app /Applications/Codex.app \
 --artifact-dir /tmp/codex-intel-build \
 --output-app /tmp/Codex-Intel.app

If no Intel codex CLI is auto-detected, the script proceeds without bundling CLI and prints:

CODEX_CLI_PATH=/absolute/path/to/intel/codex open /tmp/Codex-Intel.app

• If electron-rebuild fails, run:
  • xcode-select --install
• If app launches but hangs, ensure bundled/override CLI is Intel:
  • file /path/to/codex
• If Gatekeeper blocks opening:
  • xattr -dr com.apple.quarantine /tmp/Codex-Intel.app

• This is an unsupported community workaround.
• Auto-update is intentionally disabled unless you supply your own Intel sparkle.node.
