MacBook Pro early 2008; Yosemite OSX. My hard drive is full and I need to empty out Trash. Unable to do normal re-boot. I’ve had to use Command-R. In Terminal, it showed that all the files in Trash are “read-only” and cannot be erased. I can regain a lot of GB if only I can remove the “read-only” files in the Trash folder.
So, what is the Terminal command for changing “read-only” attributes to “read and write” that will allow me to erase the files?
