GitHub issue #25719 reports that the OpenAI Codex app for macOS repeatedly triggers macOS syspolicyd and trustd activity, accompanied by runaway CPU and memory usage. The available source metadata comes from a Hacker News discussion with a score of 3 and two comments. It does not provide the affected macOS or Codex versions, reproduction steps, logs, scope, mitigation, or an official response, so the underlying cause and prevalence remain unconfirmed.
