Today, Apple has sent out an email to Mac developers, which encourages them to sign up for the company’s Developer ID program. This will allow a developer’s apps to be properly signed ahead of the launch of OS X Mountain Lion later this year. Gatekeeper is a new feature in OS X Mountain Lion that gives users the ability to set limits on app installation.
The new “Developer ID” program provides a level of security by which developers can certify they are the developer behind a given application package. If the developer is found to behave maliciously, Apple will be able to withdraw the Developer ID associated with that developer. This will prevent applications signed with the ID from running and causing further harm to users.
Apple is encouraging Mac Developer Program members to apply for their free Developer IDs so that the software offer will be ready when Gatekeeper launches with Mountain Lion later this summer.
