Codex macOS app intermittently exits (self-aborts): exited due to SIGABRT | sent by Codex, no crash report generated

• System: macOS 26.2 (25C56), Apple Silicon (arm64)
• App: Codex.app (com.openai.codex)
• Version: 260206.1448 (565)
• Install path: /Applications/Codex.app

What happened

Codex.app intermittently quits unexpectedly shortly after launch / during normal use. No Codex*.crash / .ips is generated under ~/Library/Logs/DiagnosticReports/ (and crashpad folders appeared empty).

Evidence

Unified log shows Codex self-aborting:

launchd[1]: [gui/501/application.com.openai.codex.... [30613]:] exited due to SIGABRT | sent by Codex[30613], ran for 279866ms

Also observed TCC entitlement-related denials preceding exits, e.g.:

tccd: Prompting policy for hardened runtime; service: kTCCServiceAddressBook requires entitlement com.apple.security.personal-information.addressbook but it is missing for responsible=com.openai.codex ...

Crashpad warning observed:

[WARNING:third_party/crashpad/crashpad/util/process/process_memory_mac.cc:94] mach_vm_read(...): (os/kern) invalid address (1)

Steps to reproduce

Not 100% deterministic yet:

1. Launch Codex.app
2. Use normally for a few minutes (sign-in / open project / etc.)
3. App may exit abruptly

Expected

App should remain stable; if it crashes, a macOS crash report or crashpad dump should be produced with actionable info.

Notes

Previously also saw a separate startup high-CPU hang (~99% CPU); reinstall/cleaning caches improved that, but intermittent SIGABRT exits remain.
