My iMac è in esecuzione molto lentamente dall'acquisto. Ho fatto tutti i test e gli assegni che riesco a pensare, di seguito è riportata una copia del rapporto EtreCheck che è stato fatto oggi. Rivedendolo, oltre alla RAM non sufficiente (che non è risolvibile) non sono sicuro di cos'altro fare.
EtreCheck version: 3.3.3 (397)
