anomalia scheda di rete iMac 27 5k late 2015

[SSLMCM]

Buongiorno, vorrei una vostra opinione circa un piccolo problema che riscontro oramai da tempo sul mio iMac (come da oggetto).
a casa ho una rete lan da circa 16-17 punti rete (rj45), fatta da me quando la stavo costruendo. Veniamo al dunque, quando vado a collegare un cavo ethernet sul Mac, su preferenze rete, la connessione va e viene, ovvero, vedo la connessione ethernet che si alterna in verde-connesso-disconnesso. Fino ad ora non ci avevo dato importanza, perché avendo anche un apple watch, preferivo la connessione wi-fi, in modo da sbloccare il mac con l'orologio, ma questa mattina, visto che non avevo nulla da fare, ho cercato di risolvere il problema. Escludo che sia una coppia di fili accoppiata male sul frutto di rete, perché lo stesso cavo se ci collego il macbook pro o lo stesso iMac, usando la porta thunderbolt, funziona correttamente. Quindi mi chiedo se possa essere un problema di natura HW o SW sulla porta di rete.
Qualcuno di voi ha lo stesso problema? o ne ha sentito parlare?
di sotto incollo il check di EtreCheck.
Grazie anticipatamente

Come detto altre volte negli ultimi due anni, EtreCheck è ormai privo di efficacia diagnostica.

Qui si vede infatti solo una buona collezione di fuffa o inutilità.

Per prima EtreCheck stesso, poi Malwarebytes, il software WD.
La criptazione abilitata del disco, anche se non attiva.
Poi del software vario PolarFlow, HoRNDIS, un vecchio SoundFlower non aggiornato o i suoi resti
E TeamViewer attivo e altro.

Tutte cose che non credo entrino a far parte delle cause del problema che hai.

Ma comunque mostra cose che avresti dovuto tenere sotto controllo.
Cose che peraltro conosco solo di nome, ma forse partecipano in modo fattivo al malfunzionamento che descrivi.

- Lollipop coi suoi plugin, anche un po' datati.
- E un accesso malfunzionante ai servizi di rete.
Credo causato da qualche corruzione alle librerie condivise.

Il secondo si risolve, non so con Catalina, ricostruendole.
Sui precedenti si fa disabilitando il SIP poi eseguendo:

Codice: Seleziona tutto

sudo update_dyld_shared_cache -force

O anche

Codice: Seleziona tutto

sudo update_dyld_shared_cache -root / -force

Però devi cercare e rimuovere la causa della corruzione.
Altrimenti in breve ritrovi il problema come prima.

Controlla i plugin tutto il software che ha connessione alla rete e non è di sistema

Ho capito perfettamente, però sono convinto che il problema risieda più nell’hw.. in ogni caso proverò a fare come suggerito

Forse i reset PRAM e SMC in questo caso aiutano, altrimenti è da portare in Apple per un controllo
