Desktop app: all exec commands fail with "Failed to create unified exec process: No such file or directory (os error 2)"

Reproduce the failure in the macOS Codex Desktop app using a trivial exec command such as echo ok, then inspect ~/.codex/logs_2.sqlite for the execution error and authentication context. Compare the Desktop app behavior with the installed codex-cli and verify that shell commands execute successfully without the unified exec process error.

What version of the Codex App are you using (From “About Codex” dialog)?

Environment: - macOS, Codex Desktop app - Auth: API key in ~/.codex/config.toml (not ChatGPT login) - codex-cli 0.147.0 also installed via npm - System shell confirmed working: /bin/zsh -c 'echo ok' → ok Issue: Every exec_command fails with: Failed to create unified exec process: No such file or directory (os error 2) Even trivial commands fail (echo, date, ls, cat). Model chat works fine; only the command execution component is broken. Tried /bin/zsh, /bin/sh, login/non-login shells — same error. Reproduction: 1. Start a new thread in the desktop app 2. Ask the agent to run any shell command (e.g. "run: echo ok") 3. Error above appears immediately Tried and still broken: - Cmd+Q and reopen - Full uninstall (rm -rf /Applications/Codex.app), delete ~/Library/Application Support/Codex*, ~/Library/Caches/Codex*, ~/Library/LaunchAgents/codex - rm -rf ~/.codex/ipc/ (IPC sockets) - Fresh install + new thread Logs: Stored in ~/.codex/logs_2.sqlite (sqlite). No file-based logs at ~/.codex/log/. Note: logs show repeated INFO "remote control requires ChatGPT authentication; API key auth is not supported" — likely unrelated, but flagging since we use API key auth.
