[Solved] iScreensaver is blocked by my Mac
Hi, thought I'd join so I can learn how to make video screensaver. My first time trying. I was not able to open iscreensaver for Mountain Lion which is the system we have on my Mom's computer. It didn't trust the app because it was downloaded from the site. Is there a way to fix this problem? I really want to try out making a screensaver as soon as I can.
Any help is appreciated,
