What issue are you seeing?
Codex quit unexpectedly while I was using the Codex desktop app. Around the same time, macOS also displayed a Gatekeeper-style warning for the Computer Use helper:
“Codex Computer Use” is damaged and can’t be opened. You should move it to the Trash. This file was downloaded on an unknown date.
This appears to be related to the Codex desktop app’s Computer Use / browser automation helper. The crash report shows that the main Codex app crashed, not just the helper.

What steps can reproduce the bug?
I do not yet have a fully deterministic minimal reproduction, but the issue happened during normal Codex desktop usage involving Computer Use / browser automation.
Observed sequence:
- Open Codex desktop app on macOS.
- Use Codex normally with Computer Use / browser automation available.
- Codex unexpectedly quits.
- macOS shows the crash report: “Codex quit unexpectedly.”
- macOS also shows a warning dialog saying:
- “Codex Computer Use” is damaged and can’t be opened.
- “You should move it to the Trash.”
- “This file was downloaded on an unknown date.”
What is the expected behavior?
Codex should not crash.
The bundled or installed “Codex Computer Use” helper should remain valid, properly signed/notarized, and launchable by macOS. Computer Use should either work normally or fail gracefully with a recoverable error message inside Codex, not trigger a macOS “damaged app” dialog and crash the main Codex desktop app.
Additional information
This looks related to other recent Computer Use / macOS Gatekeeper reports, but this report is for a newer Codex desktop version:

I can provide the full macOS crash report if needed.

I hit what appears to be the same crash signature three times today on Codex Desktop 26.609.41114 (build 3888) on macOS 26.5.1 (25F80), Apple Silicon / ARM64.

Each main-process crash has a paired

Around the same window there were shutdown/cancellation logs for MCP services, but those look like consequences of the crash/shutdown rather than the root cause.I have the six macOS DiagnosticReports

Update: I reproduced the same crash signature again after updating to Codex Desktop

This time the desktop app log gives a tighter pre-crash sequence. Immediately before the crash it shows Browser Use lifecycle events:
