Removing software in Macintosh Operating System is simple matched to the procedure in another OS. Mac OSX can not support software recordings in a registry. Whether you are a first time user, or a temporary Mac user, a time will most likely arise when you will demand to remove a application or few.
 Where are programs resided in OSX?
Ctrl-Click (or right click) the alias of the program that you intend to remove, and click ”show original”. Your application picture will appear in the dock. A window will open showing the initial application’s location. In order to delete the application, you just drag it into the Trash can.
 Nevertheless, until you do so, it is good to know that exist two general types of applications for OS X, as follow:
•             The primary kind is well-known as an application, which comes with auxiliary information. When you delete that kind of application, you should make sure you delete all its auxiliary data, any of which can consume a lot of Mb on the hard disk.
•             The another kind is called program bunch, and goes packaged as a singular bundle ( for instance, Safari) without any supporting files, shown by a one icon on the dock.
 Please note: Do not clean the trash can immediately. Wait until you are sure you don’t require the program.
