Every once in a while you may need to configure certain program settings manually in OS X and for that there's the Library folder, and within it the Application Support folder. However in most recent versions of OS X, Apple has stopped showing the Library when you navigate normally using Finder, instead you will have to use the "Go to Folder..." option on the Finder menu bar. Open the Finder Go to the Menu Bar and open the "Go" menu. Select "Go to Folder..." Enter the following path: ~/Library/Application Support There's an alternative, easier way. Open the Finder, then browse the menu bar to the "Go" menu. On your keyboard hold the Option key. The Library folder will show up there.
