I want to edit parts of the system file such as ,Tiff files and some text. Every time I try I get a message that says I have no privileges to move or erase / replace this files.
I have tried "chmod" from the terminal but I still have no succes getting a message alert that command could not be used because of privileges or something.
In the system I am the Administrator and I still cant change the system file. This is a protection system but what if you just want to mess up some things like the Login screen.
Any tips will be great thanks.
