Aggiornamento Sierra...problemi Vari

Ciao a tutti, possiedo un IMAC 27 inch del 2013, dopo i vari aggiornamenti sono arrivato da alcune settimane a Sierra 10.12, ho alcuni problemi: il mio Mac è molto lento (forse troppo spazio occupato? 820 gb e solo 175 ancora liberi? quando apro le applicazioni Adobe InDesign per esempio ci vuole un mucchio di tempo e anche con Safari spessissimo appare la famigerata rotella multicolore che blocca temporaneamente il mio Mac, un peggioramento rispetto a prossima anche se il precedente sistema operativo non era esente da pecche.Se qualcuno potesse darmi qualche aiuto e suggerimento ve ne sarei grato,*

Rapporto di ieri: Il mio Mac non va bene, ieri addirittura non andava si bloccava continuamente, la famigerata rotella multicolore, avevo aperto anche alcuni programmi Adobe Indesign, photoshop, tutti regolarmente con mia licenza, versioni 3 e 5. e la cosa, l'andamento era insopportabile. Oggi un po' meglio, ma comunque alla riapertura del Mac impiega molti minuti ad accendersi e a comparire quello che ho sulla scrivania. Anche l'apertura dei vari programmi è esasperatamente lenta.Ad esempio adesso per aprire il text sta impiegando moltissimo tempo la rotella impera.**Una precisazione: *ho attivato iCloud, forse questo perché ho spostato tutto sulla nuvola? Quindi impiega più tempo, questa operazione l'ho fatta perché avevo il Mac pieno e pensavo fosse questo il motivo dei miei problemi. Comunque ho rifatto il check con 'Etrechek' se è utile lo spedisco affinchè lo possiate vedere. Ieri mattina nella*disperazione provato a*re installare*Sierra, operazione riuscita ma che non ha dato tanti risultati.
