In 10.8, no matter how I tried altering the permissions of the relevant file and folder in the Finder or "unlocking" the file (as XCode refers to it), I could not get XCode (or TextWrangler) to write to the file, so I had to alter the CNET instructions a bit. I found the method on this page from CNET, the author of which apparently found it here. It works, but it's a bit of a pain, so if anyone knows of an easier method, please contribute. After discovering that Apple, amazingly, no longer provides a built-in way to alter the duration of each slide, I set out to figure out how to change it to suit my preference. I like to use images of various quotes as my screensaver, but the default 3-second duration for each slide isn't enough for several of the quotes.
