I’m really excited to let you know that the latest OS X update is now available for download through Software Update. The main addition is support for the newly released Mac App Store, that allows you to quickly find, download and update software on your Mac.

A few weeks ago, when I wanted to start my new AIR application I had some difficulties to design its UI for both Mac and Windows. So I decided to skip Windows and develop it for Mac only. Suddenly, I think about XCode and Cocoa and after some investigations I strongly decided to learn developing originally for Mac.
