Summary
codex app installs/launches an Apple Silicon-only Codex.app on an Intel Mac, then fails to open with macOS error NSOSStatusErrorDomain -10661.
Environment
- Codex CLI:
codex-cli 0.105.0 - macOS:
13.7.8 - CPU:
x86_64(Intel)
Reproduction
- Run
codex appon an Intel Mac. - CLI reports:
Opening Codex Desktop at /Applications/Codex.app...Opening workspace /Users/tylergosla...
- Launch fails.
Actual behavior
open -a /Applications/Codex.app /Users/tylergosla fails with:
The application /Applications/Codex.app cannot be opened for an unexpected reason, error=Error Domain=NSOSStatusErrorDomain Code=-10661 "(null)" UserInfo={_LSLine=4200, _LSFunction=_LSOpenStuffCallLocal}
Expected behavior
On Intel Macs, codex app should either:
- install and launch an Intel-compatible Desktop app, or
- fail early with a clear message that Desktop is unsupported on Intel (instead of installing an incompatible app and then failing at launch).
Diagnostics
codex version: codex-cli 0.105.0
machine arch: x86_64
macOS: 13.7.8
installed app binary: /Applications/Codex.app/Contents/MacOS/Codex: Mach-O 64-bit executable arm64
spctl: /Applications/Codex.app: accepted source=Notarized Developer ID origin=Developer ID Application: OpenAI, L.L.C. (2DC432GLL2)
Additional context
codex app --helpshows default download URL:
https://persistent.oaistatic.com/codex-app-prod/Codex.dmg
- Current release assets include Intel CLI artifacts (
codex-x86_64-apple-darwin.*) but this Desktop flow ends up with ARM app bundle on Intel.
