In case your Mac is slow when booting up, applications start to hang, suddenly quit on their own or begin “beachballing” (displaying the spinning pinwheel that indicates the system is busy completing a task), when moving files on your desktop, when trying to print, when duplicating files, when adding apps to Dock, when consigning documents to Trash and so on, the problem may be due to an overloaded RAM (link to memory cleaner page).

To free up RAM processing bandwidth you should consider deleting unused programs, or at the least reinstalling the “offending” app.

Best Way To Delete Apps on Mac

Follow the steps below to fully uninstall those apps you don’t plan to use or for the apps you plan to reinstall.

Uninstall App From App Store Using Finder

Finder is the blue color icon in your Dock with a smiley face. To uninstall programs using Finder:

  • Open Finder and select Applications
  • Look for the program (or app) you want to delete from your Mac
  • Drag the icon of the app to the Trash on your Dock or control-click or right-click on the app icon and select the Move to Trash option from the pop-up menu
  • Enter your account or admin password, if required (if you have only one user account, you are the administrator)
  • Control-click or right-click the Trash icon and select “Empty Trash”

Alternatively, if you are familiar with uninstalling apps on your iPhone, iPad or the iPod you can find similar uninstall functionality within the Launchpad.

Uninstall Apps Using Launchpad

The grey color icon in your Dock with the rocket ship is the Launchpad. Uninstall apps by:

  • Open Launchpad by clicking on the icon in the Dock
  • Click and hold the app icon until icons begin to jiggle, then release the button and click again on the app’s Delete button
  • Control-click or right-click the Trash icon and select “Empty Trash”

While most Mac users delete programs on MacBook using the above methods, either of the two options don’t guarantee a complete removal of the application from your system. This is why fully deleting an app requires locating and deleting additional files the apps create on your Mac’s hard drive.

What files stored on your Mac after you remove the app?

Apps typically create numerous additional files that remain even after the app itself is deleted. Stored in hidden folders, these files are not intuitively easy to find and can be any or a combination of:

  • Web-plugins (for example, Java or Flash)
  • Application preferences
  • Application caches
  • Temporary files

All these files may or may not not seem much of a nuisance, but if you want to delete application from your system completely, all of these assisting files must be deleted also. Besides, when unnecessary files pile up clogging your hard drive, over time the problem of junk files will become more difficult to manage, resulting in your Mac losing free disk space and performing more poorly.

How to uninstall application with no leftovers

So you decided to remove a program completely, including the hidden leftover files, and chose to do so manually. Remove all the leftover files with these steps:

  1. Open Finder and from the Go menu list select the Go to Folder… option
  2. Type or paste “~/Library” into text box that opens. This will open the Library folder.
  3. Browse or use the Search field to locate folders that contain the app developer name or the name of the app.
  4. Select the files by clicking on them (or click and dragging to select several files at once). Once the files are selected control-click or right-click on them and select the Move to Trash option. Make sure you will delete the files, not the folders within which they are located as not to accidentally delete necessary files from programs you use.

In case you are not sure that the manual file removal option is right for you you can also use an automatic solution that will locate such junk system files for you and leave no leftovers behind in minutes.
