To install all 200+ screen savers:

Just double-click on Install Everything.

If it won't open because of your security settings, just control-click and select Open from the context menu.

To install only some of them:

Open the "Screen Savers" folder in this disk image and double-click each saver that you want to install. (But that might not work unless you tweak "System Preferences / Security & Privacy" first.  Just do "Install Everything", that's easier.)

To uninstall:

Open the "/Library/Screen Savers" folder and drag any unwanted savers to Trash.

For more information:

iPhone, iPad & Android:

XScreenSaver also runs on iOS and Android. The iOS version is available in the iTunes App Store and the Android version can be downloaded from the XScreenSaver web site, and they're both free!
