The process of setting Chrome as your default browser varies depending on your operating system. While you can configure Chrome as the default browser through its own settings, it’s more effective to use system settings to ensure the change applies universally across your device. You can modify the default browser on Windows, macOS, and Android. For iOS devices, jailbreaking your iDevice is required. To change the search engine, navigate to Settings > Safari > Search Engine and select Google, Yahoo, or Bing.
