I've read through the agent investigation of Codex on macOS. It looks like the default sandbox is pretty limited, however it doesn't match my experience:

- I asked the agent to change my global git username, Codex asked my permission to execute `git config --global user.name "Botje"` and after I granted permission, it was able to change this global configuration.

- I asked it to list my home directory and it was able to (this time without Codex asking for permission).
