J'ai un iMac sous OS X et depuis hier mon processeur travaille dur sans raison particulière. L'ordinateur se bloque pendant quelques minutes, puis je peux travailler à nouveau, puis il se bloque, etc.

Il semble que la situation empire lorsque j'ouvre un navigateur, notamment Chrome, mais il en va tout autrement. Savez-vous ce qui pourrait se passer ici?
