Circa tre mesi fa, la ventola del mio MacBook Pro Retina 2014 ha iniziato a girare continuamente perché launchd sta puntando la CPU fino al 70%. Quando ho controllato il file system.log, mostra questo codice più e più volte:
Jun 18 21:59:54 MacBook-Pro-2 com.apple.xpc.launchd[1] (/var/root/Library/alumni/alumni[41060]): Could not find and/or execute program specified by service: 13: Permission denied: /var/root/Library/alumni/alumni
Jun 18 21:59:54 MacBook-Pro-2 com.apple.xpc.launchd[1] (/var/root/Library/alumni/alumni[41060]): Service setup event to handle failure and will not launch until it fires.

Qualcuno sa come risolvere questo? Ho provato ad aggiornare OS X a Sierra (in precedenza sono ancora in Yosemite) ma non ha risolto il problema. Non riesco ad accedere a / var / root / Library / alumni.
