The files shown below are corrupted according to a DiskWarrior file check. It was my understanding with earlier OS versions, that the solution was to discard a bad pList, and then the parent Application (or the system itself) would refresh it in the same Library folder. I have done this with Applications before. I fixed Permissions in Disk Utility before doing any of this. And now, running 10.9.3 as my system, I navigate to the GO drop down menu at the top of the screen. While depressing the OPTION key. The LIBRARY appears in the menu. Why can't I find most of these items in the Preferences submenu of Library? Where are they hiding? Is the solution to throw them away? Does any of this matter, or is Disk Warrior sending a false alarm?
