“For apps that are downloaded from places other than the Mac App Store, developers can get a unique Developer ID from Apple and use it to digitally sign their apps,” Richard Mallion writes for Amsys.

“Apple have announced some changes for the forthcoming 10.9.5 update for Mavericks. For an application to remain trusted, developers will have to make sure the code is signed using OS X Mavericks 10.9 or later and create a v2 signature. This new requirement will also be a requirement for OS X 10.10 Yosemite,” Mallion writes. “This could mean some apps, that Gatekeeper previously allowed to run, will now generate a warning until their digital signatures have been updated. As a temporary work around, users can right-click the app and choose “Open” from the contextual menu to bypass Gatekeeper for that application.”
