Uninstalling programs in Macintosh Operating System is easy matched to the operation in other OS. Mac OSX can not support programs recordings in a registry. Whether you are a first time user, or a temporary Mac user, a day will most likely emerge when you will require to uninstall a application or few.
 Where are programs located in OSX?
Ctrl-Click (or right click) the title of the application that you wish to uninstall, and hit Show Original. Your application image will appear in the dock. A window will appear showing the primary application’s location. In order to remove the application, you easily move it to the Trash folder.
 However, before you do so, it is useful to be aware that exist two basic sorts of programs for OS X, as follow:
•             The main kind is well-known as an app, which goes with supporting information. As soon as you remove that kind of program, you should ensure you remove every its auxiliary data, many of which can consume a lot of Mb on your hard disk.
•             The alternative type is named program bunch, and comes packaged as a only bundle ( example, Safari) w/o any supporting files, shown by a single icon on the dock.
 Note: Never empty the trash immediately. Wait until you are assured you don’t need the program.
 Deleting Programs on your Mac
This segment shows us the way to delete applications from your Mac machine.
 Make certain the Mackintosh is turned on, and close all programs. Locate your hard drive pic on the desktop, that may state main disk.
 Open the Applications folder and review all the applications which were installed on the machine.
 Scan the selection of available applications and choose the ones that must be removed. To remove the particular program:
1.            Select it, and click the Ctrl button one time; in the menu which shows up, select the choice.
2.            Alternatively, find the file in the directory, select it, and move it to the Trash folder on the desktop.
 Ensure you have removed all files associated with the program.
•             Program libraries can be bulky, taking up a great deal of memory space. It is best to remove these. Examples of applications which have large auxiliary files are multimedia applications as Garageband and DVD SP. They are located in the Application Support folder inside your owners Library folder, or in "/Library/Application Support/".
•             Application settings take up very limited amount of space; you may select to retain these for further use if you want to. Those preferences are kept inside “preferences” folder within the user's Library (~/Library/Preferences), or may as well be stored inside system level Library located at the kernel of the main drive.
To erase application support files:
1.            Select “control” and “f” and apply the appropriate keywords to look for the title of the program.
2.            Identify every file inside the designated directory, and remove.
