Codex Desktop appshot fails on Intel Mac because Computer Use service is missing from x64 package

Description

On an Intel Mac, Codex Desktop exposes “Attach App Snapshot”, but every appshot attempt fails with “Unable to attach appshot”.

Environment

• macOS 15.7.7
• Architecture: x86_64 / Intel Mac
• Codex Desktop: 26.616.51431
• Install path: /Applications/Codex.app

Reproduction

1. Install/run Codex Desktop x64 on an Intel Mac.
2. Grant Screen Recording and Accessibility permissions.
3. Open a normal app, such as Finder or TextEdit.
4. Use Attach App Snapshot.
5. The capture fails.

Observed logs

Appshot capture request created ...
Codex Computer Use capture worker failed errorMessage="Failed to spawn managed Computer Use service"
failureReason=start_request_failed
Appshot capture settled ... hadAxText=false hadScreenshot=false status=failed

Investigation

The x64 app appears to expect:

/Applications/Codex.app/Contents/MacOS/SkyComputerUseService

but that file is absent in the installed app. The official x64 DMG, Codex-latest-x64.dmg, also appears to lack SkyComputerUseService.

The universal/arm DMG includes a Computer Use plugin with SkyComputerUseService under:

Contents/Resources/plugins/openai-bundled/plugins/computer-use/Codex Computer Use.app/Contents/MacOS/SkyComputerUseService

but that binary is arm64 only and cannot run on x86_64.

Expected

Either:

• ship an x86_64-compatible Computer Use/Appshot service in the x64 package, or
• hide/disable the Attach App Snapshot entry on Intel Mac with a clear unsupported message.

Actual

The UI exposes Attach App Snapshot, but capture always fails.

Additional note

Help Center chat could not be used to report this because the support widget still showed a login prompt after login and logged ChatKit element is not mounted.
