Apps won't open when I've downloaded them from the internet.
Hello,
I have a Macbook Air and for the past few weeks whenever I download apps from the internet, they will not open. I download them and the installer comes up and then I install it but when I go to my applications folder and open it the window pops up that asks if I want to open an application that was downloaded from the internet. I click open and the app disappears. The icon in the dock bounces and then disappears and the application disappears from my application folder all together. I'm not sure how this could be happening but I really need help. Thank you!
MacBook Air, OS X Mavericks (10.9.5)
