Hoi,

Ik heb het volgende met mijn trouwe iMac.
Hij hangt iedere keer op de meest rare momenten.
- Net na het opstarten
- Tijdens het gebruik van Safari
- Als hij uit stand-by komt.

Meestal duid dit mijn kennende op hardware issues, dus ik heb meteen alles getest met de hardware test.
Wat eruit komt is dat de sensor voor de harddisk niet aangesloten is, maar dat is logisch omdat ik de harddisk vervangen heb voor een grotere SSHD disk.
Ook de SMART status is gecontroleerd en de schijf is op fouten gecontroleerd. Beide geven aan dat alles OK is.
Ik heb een ettrecheck rapport gemaakt, en ook daar zie ik geen onoverkomelijke problemen naar voren komen.
Wat ik gedaan heb een paar dagen geleden is Silverlight updaten. Zou dat de boosdoener kunnen zijn?
Graag jullie ideeën zodat we verder kunnen kijken.

In de volgende post zet ik het ettrecheck rapport.

Groetjes Dennis

Je kunt eens beginnen met de 4 User Login Items te verwijderen en je Mac opnieuw op te starten, en dan kijken of je nog steeds last van het probleem hebt.

Ik heb Dropbox verwijderd. Dat was een van de laatste applicaties die ik geïnstalleerd heb.
Misschien dat dat bijt met Owncloud.
Het lijkt te werken. Machine is niet meer vastgelopen.
