Codex Desktop plugin marketplace rendering broken on macOS 12.7.6

Summary

Codex Desktop shows a broken plugin marketplace layout on macOS 12.7.6. Reinstalling the app does not resolve it. Browser / Computer Use integration also appears unavailable from the assistant side even when the UI indicates the browser/plugin is started.

Environment

• OS: macOS 12.7.6
• Codex Desktop version: 26.519.41501 (3044)
• Install location: /Applications/Codex.app

Symptoms

• Plugin marketplace page is visibly mis-rendered:
  • Large blank area on the left.
  • Plugin cards/text are clipped horizontally.
  • Search/filter controls appear offset.
  • Carousel/card content overlaps or renders outside expected bounds.
• Reinstalling Codex Desktop does not fix the rendering issue.
• Browser plugin appears enabled/started in the UI, but the assistant cannot see an available browser instance.

Expected Behavior

• Plugin marketplace should render normally.
• Browser / Computer Use plugin should expose an available browser instance when enabled.

Actual Behavior

• Plugin marketplace layout is broken.
• Browser automation interface returns an empty browser list.
• Logs show native module load failure for a bundled Codex component.

Impact

The desktop app can launch, but plugin marketplace rendering and Browser / Computer Use functionality are not usable. This blocks workflows that require in-app browser access, such as inspecting a logged-in Gmail page.

Notes

This looks like a macOS 12 compatibility issue. The sky.node native module appears to depend on a Foundation/Swift symbol unavailable on macOS 12.7.6. If Codex Desktop no longer supports macOS 12, the app should ideally communicate this clearly in system requirements and/or disable affected functionality gracefully.
