Last month, it was discovered that Apple quietly tweaked the 16 GB Wi-Fi iPad 2, equipping the device with a smaller 32-nm die shrink of the A5 system-on-a-chip previously used in the line. The tweaked iPad 2 carries an internal identifier of "iPad2,4", which was first spotted in an iOS 5.1 beta back in November, but at the time it was unclear what the model represented.

Mountain Lion's Gatekeeper feature gives users the ability to set limits on app installation, with the new "Developer ID" program providing a middle ground of security by which developers can certify that they are the developer behind a given application package. Should the developer be found to behave maliciously, Apple will be able to revoke the Developer ID associated with that developer, preventing applications signed with the ID from running and causing further harm to users
