mon iMac se synchronise beaucoup plus lentement avec iCloud que mon MacBook

Je peux encore indiquer qu'il ne semble pas s'agir d'un problème de surcharge comme le montre cette capture du moniteur d'activité:

A cet instant, cela fait deux jours que Photos indique "updating" sans que rien ne bouge.

Tous les documents sont bien visibles sur le site iCloud (via browser) et sont synchronisés entièrement sur les deux autres Mac.

Cela explique effectivement beaucoup de choses. Le démarrage prend de 3 à 5 minutes, mais j'avais fini par m'y habituer. Pour Time Machine, cela n'a pas d'importance puisque le travail se fait en arrière plan et cela explique bien mes problèmes récurrents avec iCloud.

Le boot en mode sans échec a été bizarrement nettement plus rapide et l'accès à Mail ou l'ouverure d'un browser par exemple sont aussi sensiblement plus rapides. Par contre, aucun changement sensible pour Photos.

Mes deux MacBook sont effectivement un i5 et un i7.

Je crois que cette machine a atteint sa date de péremption et que je n'ai d'autre choix que d'acheter la suivante.

Merci beaucoup d'avoir pris le temps de me fournir l'explication rationnelle à mes soucis.

Cordialement

Gérald

Merci de prendre ce cas en considération.

Il est de fin 2009 et est connecté en WiFi sur le même routeur que les deux autres. J'ai également essayé de le brancher directement par cable, sans obtenir aucune amélioration sensible.

Bonjour

J'ai finalement décidé de tenter le remplacement du disque dur. C'est maintenant exécuté et ma machine fonctionne à nouveau parfaitement.

Merci encore pour cette bonne analyse du problème.

Cordialement
