         • mac.OS
           • Stable: It is optimized to work on Macintosh computers, therefore, it is very unusual for the system to crash and throw error messages or blue screens.
           • Rápido: Gracias a su optimización software-hardware, el sistema es más rápido y fluido.
           • Seguro: Recibe menos ataques debido a su menor comunidad y a que el código de su software es secreto. A partir de macOS Catalina los archivos del sistema se guardan en un espacio de solo lectura, lo que aumenta todavía más su seguridad.
           • Incompatible: Some file formats created for macOS don't typically run on the other operating systems, except for files created in cross-platform programs or exported in the other systems' formats.
