1. The Challenge: Google Chrome Support on Catalina

It is important to note that macOS Catalina (10.15) is an older operating system. As of 2024, Google has ended official support for Chrome on Catalina. The latest versions of Chrome require macOS Big Sur (11.0) or newer.

What this means for you:

  • Security Risks: Running an outdated browser exposes you to security vulnerabilities.
  • Installation: You cannot simply go to the main Google homepage and download the latest version; it will refuse to install.
  • The Solution: You must download the specific last compatible version of Chrome.

Parte 4: Cómo crear una versión portable de Google Chrome para Catalina

Ningún desarrollador ofrece oficialmente Chrome "portable" para Mac. Pero puedes fabricarlo tú mismo en 5 minutos.

Materiales necesarios:

  • Un USB o disco externo formateado en Mac OS Extended (Journaled) o APFS.
  • La versión de Chrome descargada (archivo .app).

Pasos para crear Chrome portable en USB:

  1. Copia la app de Chrome desde la carpeta de Aplicaciones a tu USB (arrastra Google Chrome.app al volumen externo).
  2. Mueve también la carpeta de datos (opcional pero útil para verdadera portabilidad). Chrome guarda su perfil en ~/Library/Application Support/Google/Chrome. Copia esa carpeta a tu USB.
  3. Crea un lanzador personalizado:
    • Abre el Editor de Scripts (Script Editor).
    • Escribe: 
      do shell script "open '/Volumes/NOMBRE_DEL_USB/Google Chrome.app/Contents/MacOS/Google Chrome' --args --user-data-dir='/Volumes/NOMBRE_DEL_USB/ChromeData' --disable-login-animations"
    • Cambia NOMBRE_DEL_USB por el nombre real de tu unidad.
    • Guarda como aplicación (formato .app) y colócala en el USB.
  4. Ejecuta Chrome desde el USB. Así, todos los datos (perfil, historial, extensiones) se guardarán en el USB, no en la Mac anfitriona.

Ventajas de este método:

  • No deja rastros en la computadora local.
  • Funciona en cualquier Mac con Catalina.
  • Puedes llevar tus marcadores y contraseñas cifradas contigo.

Limitaciones:

  • Las actualizaciones automáticas no funcionarán bien. Tendrás que actualizar manualmente cuando estés en una Mac con internet copiando una nueva versión.

Requisitos mínimos:

  • macOS Catalina 10.15.0 o superior.
  • Al menos 500 MB de espacio en disco (para la versión instalada o portable).
  • Conexión a internet (solo para la descarga inicial).

Recommendation:

Consider updating macOS if possible, or use Firefox ESR (still supports Catalina) for better security.
