codex - 💡(How to fix) Fix Codex Desktop x64 build missing computer-use appshot service, causing "Unable to attach appshot"

Summary

On an Intel Mac, Codex Desktop shows Unable to attach appshot when using the new appshot/screenshot attachment feature. Local logs show the managed Computer Use service cannot be spawned. After inspecting the official x64 packages, the x64 build appears to be missing the computer-use plugin / SkyComputerUseService bundle that the app expects.

Environment

• Codex Desktop version: 26.519.31651
• Build: 3017
• Bundle ID: com.openai.codex
• Installed app: /Applications/Codex.app
• Machine: Intel iMac, x86_64, Intel Core i9-10910
• macOS: 26.4.1
• Locale: zh-CN

User-visible error

When invoking appshot, Codex displays:

Unable to attach appshot

Relevant log evidence

The Codex Sentry scope/log includes:

Codex Computer Use capture worker failed errorMessage="Failed to spawn managed Computer Use service"
capture settled hadAxText=false hadScreenshot=false status=failed

The app target in the same log was Arc:

bundleIdentifier=company.thebrowser.Browser name=Arc

Local package inspection

The installed app expects a managed Computer Use service under the bundled/openai plugin path and then syncs it into the Codex home directory. I inspected the app bundle and official downloads.

Installed app architecture:

/Applications/Codex.app/Contents/MacOS/Codex: Mach-O 64-bit executable x86_64
/Applications/Codex.app/Contents/Resources/native/sky.node: Mach-O 64-bit bundle x86_64

Official x64 DMG tested:

https://persistent.oaistatic.com/codex-app-prod/Codex-latest-x64.dmg

Official x64 ZIP tested:

https://persistent.oaistatic.com/codex-app-prod/Codex-darwin-x64-26.519.31651.zip

Both x64 packages contain only these bundled plugins:

browser
chrome
latex

Both x64 packages appear to lack:

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

For comparison, the default non-x64 DMG contains the computer-use plugin and SkyComputerUseService, but those binaries are arm64, so they cannot be used on this Intel machine.

Troubleshooting already attempted

Permissions were reset and re-granted repeatedly, including:

tccutil reset ScreenCapture com.openai.codex
tccutil reset ScreenCapture com.openai.codex.helper
tccutil reset Accessibility com.openai.codex
tccutil reset Accessibility com.openai.codex.helper
killall tccd

The issue persisted. This suggests the failure is not just a macOS Screen Recording / Accessibility permission issue.

Expected behavior

Appshot should attach the screenshot/app context successfully on Intel Macs, or the x64 package should include an x64-compatible computer-use service bundle.

Actual behavior

The appshot request fails immediately with Unable to attach appshot, and logs report Failed to spawn managed Computer Use service.

Suspected root cause

The Codex Desktop x64 distribution for 26.519.31651 appears to be missing the computer-use plugin / SkyComputerUseService required by appshot.
