Iphoto Library Screensaver Mac

 

The Mac’s built-in system panel allows you to set a photo library as the screen saver. That way you can gather all of your favourite photos in a photo library and then use it as the screen saver. Here’s how you can go about doing that. Setting a Photo Library as the Screen Saver. After going through the Apple setup instructions on my Mac (in iTunes, go the Advanced menu and select Choose Photos to Share and select either iPhoto or Aperture library) and on my Apple TV (Settings General Screensaver), I was viewing photos. Apple has brought Photo Library with its latest OS X update 10.10.3. Unlike the iPhoto Library, Photos app has more user-friendly features to let you manage your photos in an all-new way. The best part is that the Photo Library is almost identical to that of iOS 8’s regarding functionality.

Iphoto Screensaver

iMac G5, 10.5.7, had to repartition, reinstall from DVD, install combo update, restore from Time Machine.
Everything including iPhoto 6 seems to be working EXCEPT System Preferences for Desktop and Screen Saver. They no longer offer the option to access the iPhoto 6 library. Worse, whenever trying to select images from the folders, System Preferences hangs with the pinwheel spinning. Force Quit says that System Preferences is not responding so it must be forced to quit.
I restored the whole ~/Library/Preferences folder from Time Machine but that didn't help.
Is there a way to selectively reinstall the System Preferences software?
