Each time iTunes or Skype is launched, there is a prompt asking to allow or deny internet access. This issue is related with the OS X default Firewall, and occurs when system Firewall and Flavours are turned on.
Flavours modifies some files inside the iTunes and Skype bundles and, as a result, the codesign check fails causing the firewall to keep prompting the user to accept/deny connections. Unfortunately, this happens even if Skype and iTunes are whitelisted on the Firewall settings in System Preferences.
We are sorry about the inconvenience, but while this behavior on OS X continues, the only workaround so far is to disable the default OS X Firewall and either use a 3rd Party firewall software like Little Snitch or use a hardware-based firewall.
