UPDATE: 22 April 2026 - we have official Mac Intel now - https://developers.openai.com/codex/app
thanks for support!
Minimal helper repo to rebuild the official Codex.dmg into an Intel-compatible macOS app image.
This is an unofficial adaptation approach, similar in spirit to the Linux community port:
Codex App for Linux (unofficial)
build-intel.sh— main build script.gitignore— ignores build artifacts and local temp filespackage.json— optional conveniencenpmscript wrapper
- macOS
bash,hdiutil,ditto,codesign- Node.js + npm (used by the script to fetch Electron/runtime dependencies)
- Put your original
Codex.dmgnext to the repo folder (not inside it), so it is available as../Codex.dmg. - Run:
chmod +x ./build-intel.sh
./build-intel.shOr:
./build-intel.sh /absolute/path/to/Codex.dmgCodexAppMacIntel.dmg— rebuilt Intel-targeted outputlog.txt— full build log.tmp/— temporary build workspace
If you have problems, ask your current Codex :)
