macOS 用 Command Line Tools は Apple のページから手動ダウンロード可能
macOS 14 sonoma beta6 へアップデートし、Homebrew を実行したところ、以下のように表示されました。
Error: Your Command Line Tools are too outdated. Update them from Software Update in System Settings.
If that doesn't show you any updates, run: sudo rm -rf /Library/Developer/CommandLineTools sudo xcode-select --install
Alternatively, manually download them from: https://developer.apple.com/download/all/. You should download the Command Line Tools for Xcode 15.0.
