safari e app store non si connettono

[Jei-Jei]

Buongiorno a tutti,
vi chiedo aiuto, è da venerdì che il mio macbook air, se connesso alla linea wifi del mio ufficio, non naviga più su safari, app store, adobe e anche la sincronizzazione di dropbox non funziona più.
In compenso riesco a navigare con chrome e scarico e invio le mail con thunderbird.
Il tutto è successo da un momento all'altro, non ho installato niente di particolare, ho riavviato il router dell'ufficio ma non ho risolto.
Avevo ancora macOS catalina, ieri ho aggiornato a big sur sperando di risolvere ma niente.
Ho provato anche in modalità provvisoria, uguale a sopra, ho notato anche un rallentamento del mac.
Ho scansionato con bitdefender, e a parte qualche mail spam non ha trovato niente.
Sotto posto il report di etrecheck.
Ah dimenticavo, se lo connetto alla rete di casa o tramite hotspot su iphone naviga tranquillamente.
Spero vivamente che qualcuno possa aiutarmi.
Grazie 1000

[mattleega]

In attesa degli inevitabili insulti, provvedi a rimuovere TOTALMENTE cleanmymac e Bitdefender Virus Scanner.

Quanto meno inutili se non dannosi.
Se cerchi nel forum, capirai il perché degli insulti.

E della nausea che ci viene a furia di ripetere sempre le stesse cose.

Che poi si risolva il problema che hai postato, questo non è detto.
Il mondo della comunicazione, sta diventando scorbutico nei confronti di safari.

Però, per iniziare, bisogna partire dalla rimozione di quelle due porcherie, sempre che, leggendo al volo, non me ne siano sfuggite altre...

Vedo anche un certo "LsVRMacNetClientCtl", recentissimamente insediatosi, che non conosco ma che, pur a grande distanza, "puzza".

Sai cosè e/o a cosa serva?

[franzphone]

se connesso alla linea wifi del mio ufficio, non naviga più su safari, app store, adobe e anche la sincronizzazione di dropbox non funziona più.

Ciao, sicuramente qualche esperto ti darà le giuste soluzioni, io credo che il problema sia solo di DNS.
Puoi fare una prova andando su: preferenze di sistema--> rete--> avanzate--> DNS
Click sul tasto + nella scritta server DNS e ci metti un DNS di Google (o qualcuno più veloce) come 8.8.8.8 o 8.8.4.4 (o tutti e 2) e sicuramente Dropbox dovrebbe funzionare e anche le altre app.

P.S.: Se la mia soluzione funziona o meno, esegui comunque i consigli di Mattleega... Magari qualcuno di quei software ti sta bloccando la connessione oltre a rallentarti il Mac ed a fare danni!

[Jei-Jei]

Ciao, grazie ad entrambi, cancellato bitdefender e cleanmypc, i DNS erano già settati su quelli di google.
Comunque apportando queste modifiche non ho cambiato niente.
Non so più veramente cosa fare, la cosa strana è che è successa da un minuto all'altro e con altre linee funziona.

[Jei-Jei]

"LsVRMacNetClientCtl",
Sai cosè e/o a cosa serva?

non ho idea di cosa sia, ultimamente non ho installato niente

[franzphone]

i DNS erano già settati su quelli di google.
con altre linee funziona.

Dato che hai Chrome, vai nella barra degli indirizzi e digita:
chrome://net-internals/#dns (ti dovrebbe fare un reset DNS nella cache),
se non va riavvia il modem/router,
se non va ancora vai su terminale e digita

Codice: Seleziona tutto

sudo killall -HUP mDNSResponder && say cache svuotata

(codice imparato dal grande Faxus).
Se ancora non va, aspetta la risposta di qualcuno più esperto.

[Jei-Jei]

Ti ringrazio dell'aiuto ma niente. se faccio un backup adesso e poi un reset del mac secondo voi riesco a risolvere?

[franzphone]

Ti ringrazio dell'aiuto ma niente. se faccio un backup adesso e poi un reset del mac secondo voi riesco a risolvere?

Attendi la risposta di qualche utente più esperto.
Domanda 1: ma prima del fatto hai installato qualcosa?
Domanda 2: il router/modem a lavoro è sempre lo stesso? È stato per caso aggiunto un estender WI-FI?

[Jei-Jei]

a memoria non ho installato niente, il modem è sempre lo stesso, la vodafone station nera.
Altre 2 persone che lavorano con me, entrambe con mac continuano a lavorare senza problemi.

Prova a rinnovare il DHCP o a resettare le impostazioni di rete (ma con quest’ultimo passaggio poi dovrai rimettere tutte le password Wi-Fi).
Spero che qualcuno più competente ti dia una mano.

Buongiorno a tutti,
vi chiedo aiuto, è da venerdì che il mio macbook air, se connesso alla linea wifi del mio ufficio, non naviga più su safari, app store, adobe e anche la sincronizzazione di dropbox non funziona più.
...

In questi casi di malfunzionamento è opportuno eseguire una verifica della tua macchina.
In questo forum si consiglia l’utilizzo di  DetectX Swift al posto di EtreCheck.
Scarica l’app da qui
https://sqwarq.com/detectx/

Per primo verifica il risultato della finestra di DetectX Swift (quella dove c’è scritto STATUS:); se appare la scritta: “Search complete. No threats or problems found.” sei a posto, tutto è OK.
Se invece sono indicate stringhe di file vuol dire che DetectX ha trovato la presenza di adware o malware.
Posta quindi il risultato di questa finestra STATUS, per favore, come Codice (</>).
Questo Codice lo trovi, insieme ad altri, nella barra presente appena sopra il quadro del messaggio da scrivere. 
Posta anche il contenuto della finestra PROFILE, sempre come Codice (</>).
Va postato dall’inizio del report fino al Paragrafo che appare con la scritta: "Running Processes”.
Tutto quello che viene dopo non serve per l’analisi.

P.S.- Vedo che sei nuovo perciò ti consiglio di leggere questo tutorial che spiega come postare correttamente nel forum

Grazie, ho provato ma non risultano esserci errori.

secondo voi questa riga trovata nel router può voler dire qualcosa
SRC=192.168.1.5 DST=146.112.41.2 PROTO=TCP SPT=54743 DPT=443 MARK=0x3 DROP
l'indirizzo ip è il mio

[Scialla]

SRC= source, ovvero tu
DST= destination, ovvero l'IP al quale ti connetti
PROTO= protocol, ovviamente in tcp
SPT= source port, la porta con qui esci, la 54743
DPT= destination port, la porta con la quale, il servizio con cui sta colloquiando, comunica con te, la 443 (quella riservata alle comunicazioni in https)

MARK=0x3 DROP te lo dirà qualcuno che ne capisce di più, ma drop presumo sia relativo a pacchetti persi, boh, prova a googlare, devo scappare..

Trovata nel router? dove? in configurazione o nella log?
146.112.41.2 mi porta a un servizio Cisco/OpenDNS, l'avete inserito voi?
