Hey, guys. I have a late 2011, 13 inch MacBook Pro, OS X Lion 10.7.5. Lately whenever I download an application from the internet, it works perfectly fine if I open it in the Downloads folder, but if I move it somewhere more convenient, such as the Games or Applications folders, it won't open. I've tried moving the .zip file the apps come in, and unzipping them in the location I want the app, but the apps still won't open. When I open the apps after moving them somewhere else, I noticed that if I have the Force Quit window open, the app appears for less than half a second and then immediately closes. There are no pop-up windows saying there is an error or anything like that. All non-app files work fine. Has anyone else experienced this weird error or know what might be causing it? I hope this is the right place to post this. Also, if I move an app I opened outside of the downloads folder back to the downloads folder, it won't work.
