The Mac App Store won’t only be a new application in Mac OS X 10.6.6 but will be integrated deeply into the operating system. A MacGeneration forum poster found that when he attempted to open an unsupported file on Mac OS X 10.6.6 buildĀ 10J537 his Mac asked him if he would like to search the App Store for an application to open the unsupported file type. This new feature can be compared to a feature on Windows that allows you to search the web for applications to open unsupported files. The Mac way is more native and secure though due to Apple’s Mac App Store review process. Above is our screenshot in English.
