Ho inserito una sequenza di suggerimenti per la risoluzione dei problemi nei commenti, che sto registrando come risposta sotto. Se troviamo una soluzione, modificheremo questa risposta.
1. Assicurati che OSBundleAllowUserLoad sia vero
La pagina man di Apple per kextload dice
For most kexts, kextload must run as the superuser (root). Kexts installed under /System/ with an OSBundleAllowUserLoad property set to true may be loaded via kextload by non-root users.
Quindi mi chiedo se quella proprietà sia stata in qualche modo modificata sul tuo Mac Pro. Sul mio sistema 10.8.4, cat /System/Library/Extensions/smbfs.kext/Contents/Info.plist fornisce l'elenco di lunga durata mostrato in fondo a questa risposta. (L'ultima riga dovrebbe essere </plist> ... potrebbe essere necessario scorrere per vederlo.)
Tieni presente che la mia scheda include quanto segue:
<key>OSBundleAllowUserLoad</key>
<true/>
Se il tuo file non include queste righe (che indicano la chiave e il valore associato menzionato nella pagina man in alto), ti suggerirei:
-
Esegui il backup del file - ad esempio utilizzando
cp -p /System/Library/Extensions/smbfs.kext/Contents/Info.plist ~/Desktop/ (l'argomento -p conserva le date e altri metadati sul file)
- Modifica il file per includere le righe che ho menzionato sopra. Poiché il file è di proprietà di root, non puoi semplicemente modificarlo in TextEdit. Potresti usare
sudo nano /System/Library/Extensions/smbfs.kext/Contents/Info.plist . O ci sono soluzioni alternative che consentono l'uso di TextEdit: vedere questa risposta . (A proposito: ho il sospetto che sia possibile farlo usando defaults write , ma preferirei evitare il rischio di scrivere in modo invisibile sul file sbagliato per errore.)
- Riavvia e verifica.
Non so in che modo quella chiave e il valore potrebbero essere scomparsi, ma aggiungerlo di nuovo sembra valere la pena provare. (Non so se funzionerà - non l'ho provato, e la firma del codice potrebbe impedire questo tipo di modifica.) Inoltre: fai attenzione a eseguire il backup e modificare solo questo file!

Il poster originale (OP) ha provato questo, ma non ha funzionato.
2. Chiedi kextutil per alcuni dati diagnostici
Per prima cosa, scarica il kext (nel caso in cui ... questo non faccia danno se è già stato scaricato):
sudo kextunload /System/Library/Extensions/smbfs.kext
Quindi chiedi a kextutil di mostrare alcuni dati diagnostici ( -verbose 6 è la più alta "quantità di output" scelta):
sudo kextutil -print-diagnostics -verbose 6 /System/Library/Extensions/smbfs.kext
3. L'output diagnostico mostrava una dipendenza da un diverso kext, che mancava
L'output dell'OP includeva quanto segue:
...
/System/Library/Extensions/smbfs.kext - no dependency found for com.apple.kec.corecrypto.
...
Dependency Resolution Failures:
Only Apple kexts may link against com.apple.kpi.private.
No kexts found for these libraries:
com.apple.kec.corecrypto
... e abbiamo concluso che mancava /System/Library/Extensions/corecrypto.kext , anche se non sappiamo perché.
4. Copia il corecrypto.kext mancante da un'altra macchina (eseguendo la stessa versione di OS X)
L'OP copiato attraverso il kext mancante, riavviato e ritestato. Non avevamo ancora trovato una soluzione. Tuttavia, l'output diagnostico kextutil era cambiato, ora mostra la (lista completa) sotto:
Kext user-space log filter changed from 0xff2 to 0xfff.
Kext kernel-space log filter changed from 0xff2 to 0xfff.
Kext library architecture set to i386.
No kernel file specified, using '/mach_kernel'
Kext library recording diagnostics for: validation authentication dependencies warnings.
/System/Library/Extensions/smbfs.kext has an Apple prefix but no copyright.
/System/Library/Extensions/smbfs.kext has an Apple prefix but no copyright.
/System/Library/Extensions/smbfs.kext has an Apple prefix but no copyright.
Diagnostics for /System/Library/Extensions/smbfs.kext:
Dependency Resolution Failures:
Only Apple kexts may link against com.apple.kpi.private.
5. Forse il pacchetto smbfs.kext è danneggiato?
La mia ipotesi, basata sull'output precedente, è che il sistema operativo pensa che smbfs.kext non sia un'estensione Apple (quando è effettivamente). Ho suggerito l'OP ripristinare smbfs.kext da un backup, o copiare da un'altra macchina. Risultati attualmente sconosciuti.
Per confronto, sulla mia macchina, dove SMB sembra funzionare correttamente, l'output completo di sudo kextutil -print-diagnostics -verbose 6 /System/Library/Extensions/smbfs.kext è:
Kext user-space log filter changed from 0xff2 to 0xfff.
Kext kernel-space log filter changed from 0xff2 to 0xfff.
Kext library architecture set to x86_64.
No kernel file specified, using '/mach_kernel'
Kext library recording diagnostics for: validation authentication dependencies warnings.
