Appshots fails because managed Computer Use service/plugin is missing on macOS

Codex version

26.611.62324 (desktop app)

Environment

• macOS 26.5.1
• Intel / x86_64
• ChatGPT Plus

Problem

Appshots are visible and the double-Command hotkey is registered, but every capture fails before producing a screenshot or accessibility text.

The desktop logs report:

Failed to spawn managed Computer Use service
failureReason=start_request_failed
hadAxText=false hadScreenshot=false

Steps to reproduce

1. Open the Codex desktop app on macOS.
2. Grant Screen & System Audio Recording and Accessibility permissions.
3. Bring another app window to the front.
4. Press both Command keys to create an Appshot.

Expected behavior

The frontmost window is attached to the current or a new Codex thread.

Actual behavior

The capture immediately fails with Failed to spawn managed Computer Use service.

Additional diagnostics

• Settings > Computer Use shows only Google Chrome; the expected Any App / Computer Use installation row is absent.
• codex plugin list does not list computer-use.
• codex plugin add computer-use@openai-bundled --json returns:

Error: plugin `computer-use` was not found in marketplace `openai-bundled`

• The expected managed service executable is absent:

$CODEX_HOME/computer-use/Codex Computer Use.app/Contents/MacOS/SkyComputerUseService

Reinstalling/updating Codex and granting the macOS permissions did not restore the plugin or service.
