I have an iMac running OSX 10.8.4 and I have a large collection of photos (10,000+) that I want displayed during the screensaver. I would like to see a uniform distribution of all photos. However, I am finding that there is only a small subset of the photos that are actually shown, and there are many repeats. It is my hypothesis that OSX is choosing a subset of photos (say, 100) at the beginning of the Screensaver session, and that it is just cycling through these.
My question: is there a setting to change the number of photos that the screensaver uses?
I am comfortable with bash shell commands and am happy to modify plist files.
