Codex Desktop 26.513.20950: plugin menu stuck and Computer Use sidecar fails with Swift runtime symbol error on macOS 15.7.3

Bug report: Codex Desktop plugin menu stuck and Computer Use sidecar fails on macOS 15.7.3

Summary

After updating Codex Desktop to 26.513.20950 build 2816, two regressions appear:

1. Typing @ in the Codex composer leaves the plugin menu stuck at 正在加载插件... / Loading plugins....
2. Computer Use no longer shows the previous visual pointer / full desktop control experience. It appears to fall back to AppleScript / screenshot-style operation.

This does not appear to be caused by missing macOS permissions. Both Codex and Codex Computer Use are enabled in:

• System Settings -> Privacy & Security -> Screen & System Audio Recording
• System Settings -> Privacy & Security -> Accessibility

Environment

• Codex Desktop: 26.513.20950
• Codex Desktop build: 2816
• Bundled Codex CLI: codex-cli 0.131.0-alpha.9
• macOS: 15.7.3
• macOS build: 24G419
• Computer Use plugin: openai-bundled/computer-use/1.0.791
• Machine: Mac
• Permissions: Codex and Codex Computer Use are enabled in Screen & System Audio Recording and Accessibility.

Steps to reproduce

Issue 1: @ plugin menu stuck

1. Open Codex Desktop.
2. Open any conversation.
3. Type @ in the composer.
4. Observe the plugin section remains stuck at 正在加载插件....

Issue 2: Computer Use no longer exposes visual pointer/control

1. Start a Codex conversation.
2. Ask Codex to use Computer Use to operate a local Mac app.
3. Observe that the previous visual pointer / full Computer Use interaction is not shown.
4. The assistant appears to use fallback-style operation such as screenshots and AppleScript-like actions instead.

Expected behavior

• Typing @ should load available plugins quickly.
• Computer Use should launch normally and expose the expected visual desktop-control experience.

Actual behavior

• The @ plugin menu stays stuck loading.
• Computer Use sidecar does not appear to start normally.

Evidence

SkyComputerUseClient fails to launch

Manual launch of the Computer Use MCP sidecar fails with a Swift runtime symbol error:

dyld[35784]: Symbol not found: _swift_task_addPriorityEscalationHandler

Binary build metadata

SkyComputerUseClient declares macOS 15 as the minimum OS, but appears to require a newer Swift runtime symbol that is not available on macOS 15.7.3.

LC_BUILD_VERSION
  platform MACOS
  minos 15.0

Plugin list failures in Codex app logs

The app logs show plugin/list failures when loading the plugin catalog:

method=plugin/list
list remote plugin catalog: remote plugin catalog request to https://chatgpt.com/backend-api/ps/plugins/installed failed with status 403 Forbidden

and:

method=plugin/list
list remote plugin catalog: remote plugin catalog request to https://chatgpt.com/backend-api/ps/plugins/installed failed with status 404 Not Found: {"detail":"Not Found"}

Relevant log location:

~/Library/Logs/com.openai.codex/2026/05/15/codex-desktop-f5caf903-6e00-448a-b52a-cbaa18f0a880-16378-t0-i1-154138-0.log

Other log evidence

The logs also show screen recording reconciliation errors:

screen recording reconcile failed
kind=PermissionRequired
state=Unsupported
error_message=No shareable content available: Content unavailable: 用户拒绝了应用程序、窗口、显示器捕捉的TCC

However, the macOS UI shows both Codex and Codex Computer Use enabled for screen recording and accessibility permissions, so this may be a stale TCC/path/signature mismatch or a secondary symptom after the sidecar fails.

Notes

• Local plugin cache exists.
• Codex Computer Use.app and SkyComputerUseClient.app pass codesign verification:
