Problemi di carico sistema operativo

[brazov]

Salve a tutti.Ho un Imac 21.5 late 2012 e da quando ho installato l'OSX El Capitan ho problemi in fase di carico del sistema operativo.Mi spiego meglio.Ogni 3 o 4 accensioni senza particolari problemi il dock mi si "freeza" senza andare avanti e lasciando la data di default del 17 luglio.Allora devo spegnere tutto con il bottone posteriore e dopo alcuni tentativi il sistema si carica regolarmente.In alcuni casi addirittura durante la progress bar di carico mi esce la segnalazione che la tastiera non e' collegata via bluetooth o mi appare il desktop con la deathball che gira a vuoto.Non so se sia un problema di finder o di utilizzo eccessivo di memoria visto che sono impossibilitato in quei momenti a fare controlli.L'utility disco non da problemi.Vorrei evitare di reinstallare tutto da capo avendo parecchi dati sul pc.Una volta caricato l'osx comunque il mac e' velocissimo e senza alcun problema.
Scusate se mi sono dilungato ma questo problema mi sta facendo impazzire.

È un po' difficile dire qualcosa con pochissimi dati su Mac, sistema e installazioni.

Ti consiglio un EtreCheck,

Posta il check come testo tra i tag Code, per favore.
Sarà più facile capire da dove deriva il problema.
Se non sarà possibile vedremo anche un syslog, successivamente

[faxus]

I tuoi problemi dipendono dall'antivirus Avira.
Eliminalo e tornerà tutto a posto.
Fallo con cura e precisione, guardando le FAQ del produttore.

Gli antivirus per OS X sono inutili e generalmente molto dannosi, persino pericolosi per la sicurezza.

Inoltre elimina del vario adware che hai collezionato.
Con MalwareBytes Antimalware per Mac.

Dovrebbe sparire qualsiasi problema, ma ripeti il check

[brazov]

Ho eliminato Avira,installato Malwarebytes ed eliminato adware.Ora terro' monitorati gli avvi di sistema nei prossimi giorni.Per il momento "faxus"ti ringrazio tantissimo per il tuo tempo e la tua disponibilita'

[tighine]

Malwarebytes for Mac puoi disinstallarlo. Come suggerito da Faxus, ripeti l'Etrecheck.
