Errori SUID etc

Salve cari utenti dopo il natale ci troviamo alle porte del nuovo anno e come per incanto mi ritrovo dei problemi al mio imac core 2 duo 20"...
Mi spiego ho fatto un check del mio disco machintosh su Utility e mi è venuto fuori:

Allora mi sono imbottito di pazienza e ho fatto il boot con il disco di Leopard .. , usando sempre utility e cercando di riparare i permessi del S.O. ... finale = mi dà sempre le stesse scritte l'ho fatto diverse volte ma sempre uguale.

Arrivato a questo punto non so come far sparire questi errori e nemmeno ne capisco le gravità...
Chiedo Aiuto al forum per cercare di ritrovarmi con il Mac bloccato o chissà cosa...
Ciao e Grazie Anticipate
