Consigli su problema per me inspiegabile (processo inkjet6))


Recommended Posts

Salve,

scrivo per chiedere consiglio su un problema che mi si presenta da un paio di giorni:

il mio macbook (prima serie unibody in alluminio) risulta parecchio lento e quasi sempre impallato -- fatica ad aprire docs in pdf, e applicazioni semplici tipo ical e mail.

Guardando su monitoraggio attività mi accorgo di avere uno strano processo sempre attivo (anche se ne forzo l'uscita o riavvio).

Il nome del processo è Inkjet6: quando si avvia, per i primi 10 minuti mi usa una delle due cpu al 98%, e mi occupa tutta la ram (uso mem virtuale 3GB, reale 600MB); poi all'improvviso smette di adoperare la cpu (che torna a zero) e però si tiene tutta la ram occupata in precedenza.

C'è nessuno che saprebbe dirmi di che cosa si tratta e come potrei risolvere? Ho campionato il processo con monitoraggio attività (nella fase in cui non adopera la cpu, ma solo la memoria), copio sotto i risultati (per me indecifrabili)

Grazie in anticipo per l'aiuto!
