Hi ..
Apps such as Little Snitch, Growl, and MacKeeper can prevent apps from downloading
Disable anti virus software if installed
Make sure the firewall is turned off in System Preferences > Security & Privacy > Firewall
Make sure Gatekeeper is enabled
Open System Preferences > Security & Privacy then select the General tab.
Make sure either Mac App Store or Mac App Store and identified developers is selected.
If that area is grayed out, click the padlock icon to proceed.
