Estoy ejecutando OS X El Capitan, en un iMac (27 pulgadas, mediados de 2010). Al usar "top", noté que mis sistemas siempre ejecutaban "ReportCrash"; Miré en los registros, y encontré:
1/25/18 12:32:51.464 PM com.apple.xpc.launchd[1]: (com.apple.MRTd) Service only ran for 0 seconds. Pushing respawn out by 10 seconds.

Parece que hay un problema con MRT, MRTd. ¿Son esas cosas de seguridad? Sé muy poco ...

También tengo algunos problemas extraños: el navegador (Safari) sigue cargando continuamente nuevas páginas, en YouTube "puede que estés interesado en cualquier cosa" (las individuales, funcionan bien). Además, la "nueva interfaz" de Google Mail a veces me obliga a iniciar sesión varias veces. De lo contrario, vuelve a mi página original cuando inicio el navegador.
Me interesa no solo solucionar mi problema, sino también la integridad de mi sistema.
