Later frames include V8/Node and Rust image/temporal symbols, then ChromeMain and main.

A few native modules were loaded in the process:

better_sqlite3.node
sparkle.node
sky.node
browser-use-peer-authorization.node
devicecheck.node

System log entries immediately before the crash do not show a clear Codex fatal/assert message. The only notable nearby errors were CoreSpotlight/Biome donation errors around 18:11:12, about four seconds before the crash:

2026-06-29 18:11:12.116 Codex[...] [com.apple.corespotlight:index]
Failed to request donation Error Domain=CSIndexErrorDomain Code=-1000 "Failed to request donation"

I am not sure this CoreSpotlight error is causal; it is included only because it is the only nearby system log error before the crash.

What steps can reproduce the bug?

I do not yet have a deterministic minimal reproduction.

Observed sequence:

1. Launch Codex Desktop 26.623.61825 on macOS 27.0 (26A5368g).
2. Use Codex normally.
3. Leave the app running in the background.
4. After about 24 minutes, Codex unexpectedly quits.
5. macOS records EXC_BREAKPOINT / SIGTRAP on Thread 0 CrBrowserMain.

What is the expected behavior?

Codex Desktop should keep running. If a Chromium/V8/Node/native-module operation fails, it should fail gracefully without terminating the main app process.

Additional information

This looks related to the recent family of Codex Desktop macOS crashes with EXC_BREAKPOINT / SIGTRAP on CrBrowserMain, but this report is for a newer app build and newer macOS build:

• #30531 reports crashes on 26.623.61825, but without crash details.
• #30005 reports CrBrowserMain startup crashes on 26.616.81150.
• #27880 reports repeated CrBrowserMain / EXC_BREAKPOINT crashes on 26.608 / 26.609.
• #28274 and #26863 also include similar macOS CrBrowserMain crash signatures.

I am not attaching the full raw crash report publicly because it contains machine identifiers and local runtime details, but I can provide a redacted .ips excerpt if helpful.
