Me he comprado un mac el 17 de julio de 2016. He leído que este comando puede decir si el primer usuario de este mac era yo mismo:
ls -lt /private/var/db/ | tail -30
A continuación, se muestra 30 listas. Algunos de ellos son fáciles de entender, pero hay muchos que no sé lo que significan. Algunos también tienen extraño fechas dentro de ellos de la siguiente manera:
Las primeras listas de aspecto como este:
-rw-r--r-- 1 root wheel 237 8 2 2015 QuickTimePlayerVersion.plist
-rw-r--r-- 1 root wheel 0 8 2 2015 gke.sigs
Las listas en el medio este aspecto:
drwxr-xr-x 4 root wheel 136 7 7 2016 mds
drwx--x--x 4 root wheel 136 7 7 2016 TokenCache
En la fecha compré este Mac, esto ocurre:
drwxr-xr-x 5 root wheel 170 7 17 2016 ConfigurationProfiles
-rw-r--r-- 1 root wheel 0 7 17 2016 DetachedSignatures
drwxr-xr-x 3 root wheel 102 7 17 2016 efw_cache
Hacer estas entradas de la lista de demostrar que la Mac que he comprado se habían usado antes?
Editar: Yo uso Klanomath la sugerencia. Yo ingrese el comando siguiente
ls -altUT /private/var/db/
El resultado:
