@etraut-openai Looks like this is already addressed by #9823 (switching self-update to use
brew upgrade --cask codexto avoid the rename warning / ambiguity).If that PR covers the remaining edge cases (e.g. systems with both formula + cask present), this issue can probably be closed once it merges/releases.
Yes, PR #9823 references this bug report. Github automatically closes linked bugs when a PR is merged. It's a convenient automation.
