What version of Codex CLI is running?

0.111.0

What subscription do you have?

Plus

Which model were you using?

N/A, this is not a task that uses a model (I presume)

What platform is your computer?

Darwin 21.6.0 x86_64 i386

What terminal emulator and version are you using (if applicable)?

iTerm2

What issue are you seeing?

Codex Desktop installer bug: installs arm64-only app on Intel Mac

What happened:

  • Ran codex app
  • Installer downloaded and installed /Applications/Codex.app
  • App would not launch

Observed errors:

  • open -a /Applications/Codex.app ... fails with NSOSStatusErrorDomain Code=-10661
  • Direct launch fails with: bad CPU type in executable: /Applications/Codex.app/Contents/MacOS/Codex

Evidence:

  • uname -m => x86_64
  • file /Applications/Codex.app/Contents/MacOS/Codex => Mach-O 64-bit executable arm64
  • LSMinimumSystemVersion is 12.0, so this is not a minimum macOS version issue
  • codesign/spctl passed, so signing/notarization is not the problem

Expected:

  • On Intel Macs, codex app should not install an incompatible app. Instead, it should inform the user with a clear unsupported-platform message.

What steps can reproduce the bug?

I can reproduce it on this Mac by running codex app. If I delete the installed app and try again, same thing.

What is the expected behavior?

On Intel Macs, codex app should either install an x86_64 or universal desktop build, or fail early with a clear unsupported-platform message instead of installing an unusable app.

Note that this is related to, but different from https://github.com/openai/codex/issues/10410 , because it has a different expected behavior:

  • this issue: Don't install an invalid app (i.e. fix a bug)

rather than

  • prior issue: Please support Intel Macs (i.e. produce a new feature)

Ah, I'm overeager; I see https://github.com/openai/codex/issues/12941 is closed as a duplicate of https://github.com/openai/codex/issues/10410 , but this issue is not a duplicate of https://github.com/openai/codex/issues/10410, so I'm re-opening this.

Yes, the macOS app isn't yet available for Intel-based Macs.

@etraut-openai , (edit), if I understand correctly, you interpreted this bug report as question about whether the macOS app is available for Intel-based Macs.

This bug report is asking that codex app not install an incompatible-architecture app, but instead print a message informing the user.

e.g. something like this, as a minimal, concrete example of what I mean: https://github.com/gbodeen/codex/pull/1
