codex app installs ARM-only Codex.app on Intel Mac; launch fails with NSOSStatusErrorDomain -10661

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

1. Run codex app on an Intel Mac.
2. CLI reports:

• Opening Codex Desktop at /Applications/Codex.app...
• Opening workspace /Users/tylergosla...

1. 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

Additional context

• codex app --help shows 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.
