Ho comprato un mac il 17 luglio 2016. Ho letto che questo comando può dire se il primo utente di questo mac era me stesso:
ls -lt /private/var/db/ | tail -30
Quindi mostra 30 liste. Alcuni di loro sono facili da capire, ma ci sono molti che non so cosa significano. Alcuni hanno anche date strane all'interno di essi come segue:
I primi elenchi assomigliano a questo:
-rw-r--r-- 1 root wheel 237 8 2 2015 QuickTimePlayerVersion.plist
-rw-r--r-- 1 root wheel 0 8 2 2015 gke.sigs
Gli elenchi nel mezzo hanno questo aspetto:
drwxr-xr-x 4 root wheel 136 7 7 2016 mds
drwx--x--x 4 root wheel 136 7 7 2016 TokenCache
Alla data in cui ho acquistato questo Mac, questo si verifica:
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
Queste voci di elenco dimostrano che il Mac che ho acquistato era già stato utilizzato in precedenza?
Modifica: Uso il suggerimento di Klanomath. Ho inserito il seguente comando,
ls -altUT /private/var/db/
L'output:
