¿Por qué no puedo eliminar iTunes y cómo eliminarlo?

Si solo desea evitar que se inicie, ejecute

sudo chmod 000 /Applications/iTunes.app

debería hacer el truco. Debe repetirse después de cada actualización de OS X / iTunes, pero esto también se aplica a cualquier solución que implique la eliminación de aplicaciones estándar.

PD: solo para poner las cosas en perspectiva en lo que respecta al espacio en disco:

root@Mithos:/Applications$ du -sm iTunes.app Chess.app Game\ Center.app Stickies.app Photo\ Booth.app Photos.app 
191 iTunes.app
5   Chess.app
3   Game Center.app
5   Stickies.app
5   Photo Booth.app
31  Photos.app

Incluso en un sistema con solo un SSD de 128 GB, eliminar 200 MB no le da mucho.

Apple no admite la desinstalación de iTunes. Arrastrarlo a la papelera y tratar de eliminarlo le dará un mensaje "iTunes no se puede modificar o eliminar porque OS X lo requiere".

Incluso si lo haces manualmente, volverá con las actualizaciones del sistema operativo; y puede romper ciertas cosas como algunas asociaciones de archivos y capacidades de conexión / sincronización de iPhone.

Probablemente, tu mejor apuesta es simplemente dejarlo allí e ignorarlo.

rm -f -r /Applications/iTunes.app

lo eliminé para mí junto con Chess, Game Center, Photo Booth & Pegajosos.

Primero has descargado la aplicación ituneshelper (usa el monitor de actividad), no necesité hacerlo ya que elimino la basura innecesaria de OS X inmediatamente después del lanzamiento.

Es falso que sea requerido por OS X, es solo requerido por Apple para venderte cosas.

aquí hay una aplicación AppleScript para automatizarla, o simplemente puede pegar lo siguiente en el Editor de AppleScript y adapta a tu gusto:
