Uninstalling programs on a Mac is not the same as on a PC. Some are even very difficult to remove.

In this tutorial, we explain how to separate yourself from these software and their preference files on your Mac.

The difference between Windows and macOS

Under Windows, wizards help you install and uninstall programs. However, sometimes fragments are still in the C: drive, making it difficult to remove them completely from Windows.

When in 2001, Apple adopted NeXT OS and launched the Mac OS X system, the American company decided to keep the concept of Unix, that is, to separate the system files from the user’s workspace. . This allows the user to easily locate and delete these files.

On Mac, applications are mostly stored in / Applications and your configuration preferences are saved under ~ / Library / Preferences /.

Their ancillary files are located in ~ / Library / Application Support or under / Library / Application Support.

To access all of its locations, open FinderTo go, Press on Alt (option) and select Library (between Start and Computer).

To launch your programs with all their files, you just need to double-click on them or on their icon placed in the Dock.

To uninstall them, you will simply have to drag them to the Trash.

If you are using a Mac with a guest account, then you will be asked to enter the administrator password.

Delete preferences files on Mac

In addition, from Library you can also delete preference files. Since Mac OS X10.6, this one is hidden by default, follow this complete tutorial for the locate, or the indications given below.


When your Library appears, open it by clicking on it and delete the preference files.

Applications that are difficult to remove

Some software, like Adobe, Microsoft or MacKeeper, are a little more complicated to erase.

MacKeeper, for example, promises you cleaning up and improving the performance of your Mac. For this, it takes detours for its installation, which makes its removal particularly difficult.

Moreover, even after uninstalling it, the app Uninstall is not able to clean everything …

You should also watch out for daemon, which are computer processes that run in the background. These allow hidden applications to launch when macOS starts up.

A little more savvy Mac users use the Mac Terminal to make sure they’ve cleaned up (ApplicationsUtilitiesTerminal).

If you want, then you can also use the app Find Any File (English) available for € 8.99 on the Apple Store. It is a more powerful and faster program than Spotlight. It locates any files, even hidden ones, by scanning your internal and external hard drives. In addition, its interface is identical to that of Finder, so you will not be confused.

Be aware, however, that it should be used with caution, as you may erase system files. If so, then macOS will ask you to enter the administrator password.


Shareware or cleaning software

Shareware (contributory software) like Uninstall, AppCleaner, AppDelete or CleanApp can help you find applications and their “hidden” files and take care of deleting them.

To thoroughly clean your macOS, we recommend CleanMyMac X.
