The Mac app store is an application market place that Apple released with Mac OS X 10.6.6 update. Usually we install Mac apps directly after downloading it from the internet or from media discs. Mac app store is like the iTunes store for the iPhone, iPad and iPod Touch. Here we use Apple ID to purchase or download applications directly from the cloud, and the upgrades can be installed like that in iOS devices.
It is pretty easy to install apps from the store, but there is no direct option to uninstall or remove Mac store and apps installed. However, you can do that through a method given below.
