Allora, il mio iMac (metà 2011) ha installato Sierra 10.12.6 (se non sbaglio non posso aggiornare a versioni più recenti...), e spesso è lento. Dato che ci lavoro vorrei migliorare quanto più possibile la cosa (dovrei comprarlo nuovo forse, ma non si può ora). Con EtreCheck ho notato che sto usando quasi tutta la RAM, e al momento non posso nemmeno aggiungere i due slot da 2 GB che penso farebbero la differenza, o quantomeno migliorerebbe le prestazioni. La mia domanda è: se tornassi a una versione precedente di OS le cose migliorerebbero o sarebbe una scemenza?
Vi lascio qui il report di EtreCheck:
