To preface this: I'm sure this has been asked but I don't know exactly what I'm searching for or what terms to use, so I am going to ask here by explaining my situation.
I am logged onto a network OS on a host machine (10.9) and I need to view and edit files on the Macintosh HD that is on this actual host machine. The reason why I need to do this is the user's machine is kernel panicking because of a Trend Micro kext in his OS. Whenever I try to go into the user library on Macintosh HD to delete the plists as well, I get "Permission Denied" even when using sudo. I do have the username and password of the user that I'm trying to edit so my question is: How do I log in, through terminal, as that user to edit things inside that users Library folder?
Hopefully this makes sense -- if not let me know and I can try to clarify further.
Edit: To further explain myself and why I'm going about it this way is simply because I'm curious. If I boot into safe mode it works just fine as it doesn't load the kext. I'm just wondering how this would be done.
