How to uninstall app in mac

Using LaunchPad in Mac OS X 10.11, 10.10, 10.9, 10.7, 10.8, and newer does not require you to empty the Trash afterwards, it’s all handled immediately. This should be familiar to anyone who has used an iPhone, iPad, or iPod touch, since the interface and tap-and-hold method is identical to what is in iOS. This is yet another reason that upgrading to Lion is compelling, it makes the Mac experience even simpler while still retaining the full power and potential behind Mac OS X. Deleting apps from LaunchPad wil

Some applications will also leave behind some preference files and caches, generally these don’t harm anything to leave around, but if you want to delete them it’s just a matter of locating the apps support files and removing those as well. If you’d rather not dig around in these files yourself, you can turn to a utility like AppCleaner to delete the application along with all of it’s respective scattered preference files, but for those who would like to do this on their own, you can typically found these type of files in the following locations.

Application Support files (can be anything from saved states, preferences, caches, temporary files, etc):

~/Library/Application Support/(App Name)

Preferences are stored at:

~/Library/Preferences/(App Name)

Caches are stored in:

~/Library/Caches/(App Name)

Sometimes you will need to look for the developer name rather than the application name, since not all app files are identified by their name.

Again, these generally don’t do any harm to leave be, but they can take up some hard drive space, so users with smaller SSD’s might want to be pay more attention to the cache and support files that some applications generate. The biggest offender here is Steam, where if you play a lot of games it tends to gather a very large Application Support folder.

This is somewhat rare on a Mac, but some applications include their own uninstaller apps to remove all traces of an application. These are typically from Adobe or Microsoft because some of those applications will install more apps that aid the program, or place library files and associated application dependencies elsewhere in OS X. For example, Adobe Photoshop might install the Photoshop application in addition to Stock Photos, Help Viewer, Adobe Bridge, and others. In this case, you can either manually delete all the accompanying apps, or just run the uninstaller application that comes on the original installation method, whether it’s from the web or a DVD. If the app you wish to uninstall does include a dedicated uninstaller application, it’s generally a good idea to go that official route of removing the app so that the other associated items are removed from the Mac as well.
