Safari 5.2, Xcode 4.4 and Gatekeeper, the application installation restriction system, are available in Mac OS X 10.7.3

  because OS X Mountain Lion is available for download, Apple also released Safari 5.2 and Xcode 4.4 for application developers for Mac OS X. These two versions of the applications are specially designed to include support for the new operating system and the new features implemented in it by Apple. In the new version of Safari, Apple moved the search box to the address bar and chose to highlight the name of the accessed domain, redid the icon of the Reader application and updated the appearance of the interface.

  Moving on now to GateKeeper, the system that restricts the possibility of installing third-party applications that do not have a Developer ID, I will tell you that he is available for testing even in Mac OS X 10.7.3 so it will not be an exclusive function of the new Mountain Lion. Apple claims that developers can access this new system using a few commands that can be run directly in the Terminal application, but testing it now could make it impossible to install many applications.

Mac OS X users will soon have the option of turning on Gatekeeper, a new Mac OS X security feature. When a user does this, the system provides an additional measure of safety: it blocks that user from opening newly downloaded applications that are not Developer ID–signed. In this scenario, the same user is easily able to launch downloaded applications that are Developer ID-signed. 

By default, Gatekeeper is not enabled in Mac OS X v10.7.3. For testing purposes, you can turn it on by using the new Mac OS X system policy control command-line tool, spctl(8).

  If you are interested in testing GateKeeper on Mac OS X Lion 10.7.3 then open the Terminal application from Applications>Utilities and run the command sudo spctl –enable. After running it, you will activate GateKeeper and you will no longer be able to install applications that do not come from the Mac App Store or do not have a Developer ID. To disable GateKeeper, you must replace the enable function with the disable one.

  1. I can not believe!!!!! They thought to implement the most cocoa feature in Chrome in the new Safari (search in address bar). Phew! It's the beginning of the end 🙁

  2. Because the search is the search and the address bar is the address bar and the ONLY ones who forced them to stay together were those from Google. It's ok for them, it was an integrated part of the OS they dreamed of making, but the rest of the world? They have no justification. The worst part is that, probably, they will port this change of philosophy to Safari Mobile as well, and then have fun. Over 60.000.000 regular users with a mode of use will do a collective double-take.
