Summary

Codex Desktop on macOS is repeatedly crashing/reloading the renderer and returning to the home page. Restarting the app does not resolve it.

Environment

  • App: Codex macOS desktop
  • Version observed in process args: 149.0.7827.197
  • Architecture: arm64
  • Date observed: 2026-07-01 through 2026-07-02

User-visible behavior

The Codex app briefly appears to restart/reload, then exits back to the home page. This has happened repeatedly, including after restarting the app.

Evidence

Crashpad sidecar records in Application Support/Codex/Crashpad/pending are being created repeatedly. Recent timestamps after clearing/restarting include:

2026-07-02 11:09:54
2026-07-02 11:11:32
2026-07-02 11:13:08

Latest sidecar content shows:

{"osarch":"arm64","ptype":"renderer"}

Earlier records appeared every ~1-2 minutes during the same session, all consistent with ptype: renderer.

Mitigations tried

  • Restarted Codex app: issue continued.
  • Stopped accumulated Computer Use / node_repl helper processes: issue continued.
  • Moved GPUCache and Crashpad pending aside to reset renderer/cache state: issue continued.
  • After cache reset, a new renderer crash appeared at 2026-07-02 11:09:54.

Related observation

Computer Use helper processes appear to grow in repeated groups after these renderer reloads, for example:

  • SkyComputerUseClient mcp
  • cua_node/bin/node_repl

Stopping these helpers reduces process accumulation temporarily, but the renderer crash loop still continues.

Expected behavior

The renderer should remain stable and the app should not reload/return to the home page repeatedly.

Notes

Local paths/usernames have been intentionally redacted from this report. A local diagnostic text report with process snapshots and Crashpad timestamps is available if maintainers need more detail.

I don't know if it same or not, but for me its helps:
I just installed Codex CLI today, and get similar symptoms: desktop app shows starting page over and over again reloading.

So i start codex-cli and it says 401 " MCP client for codex_apps failed to start: MCP startup failed: handshaking with MCP server failed: Send message error Transport".

So i use codex logout, codex login and after that desktop apps works fine

Update: This macOS renderer crash-loop behavior has accelerated with recent Codex Desktop updates. On the current build (26.727.51351), renderer crashes/reloads now recur every 2–3 minutes during active use, making the application nearly unusable. The main app process remains alive while the window blanks and reloads, and Crashpad continues to show renderer failures. This is materially worse than the earlier cadence reported here.
