App Cleaner & Uninstaller


App Cleaner & Uninstaller is a special tool for completely uninstalling an application from macOS. Although apps could be trashed just by putting the icons into the Trash, App Cleaner allows you to uninstall apps correctly and completely. The program also finds the leftovers of previously removed apps and allows you to operate extensions installed on your Mac.

Just launch App Cleaner & Uninstaller and in several seconds you will see the statistics about your applications and service files, including a number of files, their sizes, unused apps, startup items and other important information about your disk space usage.

Apps’ Service Files

When a program runs, some unnecessary files remain. These files include caches, logs, preferences, autosave files, etc. Some apps even create additional folders with their own files, which are not easy to find.

cache folders

It’s clear that such files can’t be removed by simply putting them into the Trash. Little by little, these files fill up disk memory on your Mac, keeping unneeded data. App Cleaner & Uninstaller allows you to perform a complete cleanup of applications and remove all the cache data created when the apps run.

You can view a list of all apps with their service files in the Applications section.

With App Cleaner & Uninstaller, you can view all of the programs installed on your Mac. When you are in the Expert mode and click on any app you will see a list of its temporary files and folders in the right column. These files should be cleared when you uninstall them. You can remove an app completely or delete only some of the files in its service folders.

Remaining Files

Moreover, some apps could have been removed earlier by a regular trashing procedure, and as a result, absolutely useless files could still be on your Mac. App Cleaner & Uninstaller finds and allows you to clear the remaining files – broken service files from already deleted applications.

View the list of service files from apps you have already removed in the Remaining Files category.

Startup Programs

Startup programs are the programs that run automatically when you boot your Mac. The problem is that when too many programs start automatically, your Mac starts to operate slowly.

App Cleaner & Uninstaller allows you to easily operate startup items, disable and enable them with one click and even remove some of them. macos remove application


Having too many browsers or app extensions can also slow down your Mac. Moreover, there may be some features that you don’t use or plugins installed automatically that you don’t even know about. App Cleaner & Uninstaller allows you to remove all these useless additions:

Default Apps

If you prefer to open your files with a specific application, you don’t need to use the command “Open with” every time. For example, you want to open your images with Photoshop instead of the Photos app. While you can just open Photoshop and then import your image, it will be much easier to double-click on the file and automatically open it with the Photoshop app.

With App Cleaner & Uninstaller you can change the file associations with a few clicks.

Skip List

Any of the listed items can be added to the “Skip List” so that they will not be shown in the scanned list. Make a right-click on the file and click “Add to Skip List” or go to the Preferences → Skip List tab and there add your items.

Applications Section

App Cleaner & Uninstaller starts to scan the Applications folder right after being launched and shows all of the installed apps on your hard drive. It finds all temporary files created by each of these applications.

You can view a list of all apps with their service files in the Applications section.
When you click on any app you will see short information about it in the right column: total size, number of service files and so on.

You can remove an app completely or delete only some of the files from its service folders.

If you want to delete an app completely, just select it and click the Uninstall button. Also, you can select all its files in the right section and click the Remove button.

Resetting applications

For your convenience service files from each application are grouped and displayed by their respective categories:

  • Executables – application’s program files. Note: Executables with the same identifier are combined to one application.
  • Application Support – app-specific data and support files. These are files that an application creates and manages on behalf of the user. Also can include files that contain user data.
  • Plugins – application components that add specific features to another application.
  • Shared – application service files that are shared between users of the OS X.
  • Library – app-specific data and support files shared between other applications.
  • Growl – components that support notifications by Growl notification system in the application.
  • Caches – cached data that can be regenerated as needed. Applications never rely on the presence of cache files.
  • Containers – home directories for any sandboxed applications.
  • Preferences – the user preferences files for the application.
  • Logs – log files for the console and specific system services.
  • Cookies – data files with web browser cookies.
  • Crash Reports – crash report files of the application.
  • Preference Panes – special application plugins dynamically loaded to System Preferences to customize application settings.
  • Login Items – agents, daemons and items in the System Preferences to support application start on system launch or user’s log in.
  • Dock Icon – alias to the application in the Dock bar.
  • Supported Document Types – file types supported by the application.

These sections are supportive or service files that appear while the app operates. You can remove just the supporting files as well, which means performing an application reset. Hence, if you get rid of them, your app will be clean and you can start using it from the very beginning.

View Supported Documents Types

Some apps may open documents in specific formats, such formats are listed in a section called Supported Document Types.

View specific file types

You can click on each file from the Supported Document Types to view the files found of a specific file type. App Cleaner & Uninstaller displays a search button for every format.

Startup Programs Section

In the Startup Programs section, you will find the list of all launch agents, login items and system daemons installed on your Mac.

  • Launch Agents are hidden or background programs that run on user login or system startup. You can disable the agents’ auto-launch or delete the launch agents from the disk. App Cleaner displays agents stored in the current user and system folders and allows you to manage them.
  • Login Items are user-facing programs that run on user login. The app displays a list of installed applications that have special agents and you can disable their auto-launch. You can also manage login items accessible through System Preferences.
  • System daemons are the files that contain scripts to automatically manage system service processes. System daemons are loaded on system startup and they run processes for all the users on Mac.

In the Extensions tab you will find the files of the following types:

  • Installations – files that are used to set up programs. App Cleaner displays a list of installation files stored on the Startup disk. You can remove unneeded files to clean your disk space.
  • Web Browser Extensions – small software programs that can modify and enhance the functionality of a web browser. They can change the user interface of the web browser without directly affecting the viewable content of a web page. App Cleaner displays extensions for installed web browsers and allows to uninstall extensions.
  • Screen Savers – programs that fill the screen when the computer is not in use. App Uninstaller displays installed screen savers and allows you to remove them to free up disk space.
  • Preference Panes – special dynamically loaded plugins to customize working of some installed services or applications. The app displays installed Preference Panes and allows you to completely remove them together with their service files.
  • Internet Plugins – program components that add specific features for Internet browsing. App Cleaner displays installed plugins and allows you to remove them. Please be careful when you remove system plugins because it may harm the system operations.
  • Widgets – simple and easy-to-use programs launched by the Dashboard app. Please be careful when removing core widgets because they do not spread separately and can only be installed with the system.

  1. Go to the Extensions section.
  2. Select the unneeded extensions and click the Remove button to delete them completely. Next to the extension type, you can see how many items you have selected – the number in the circle.

Remaining Files Section

Most apps are removed by simply putting them into the Trash. In that case, all of the service files remain on the disk, littering your Mac. Such broken service files are unnecessary and they just take up your disk memory. These files are called remains.

App Cleaner & Uninstaller allows you to find such “forgotten” files and clear them. Just launch app and it will do all the work – find all the apps on your Mac with service files, as well as remains – the forgotten files.

Go to the Remaining Files section to view them. You can use the CMD+4 shortcut.
macOS uninstall app
There are filenames of applications’ file sets in the left column. Because the app has been deleted, there is no way to know their names. So, these files are named as the apps had created them.

If you select one of the elements from this list you will see all related files remaining from the removed application in the right column. Delete the remains by selecting the files and clicking the Remove button in the right corner.

Note that some apps can create and save their service files in different folders, even when it contradicts Apple’s requirements for the organization of temporary and service files. In this way, these files can be found by App Cleaner & Uninstaller as well and be displayed as Remaining Files, though in reality these files are used by applications.

Please, make sure you don’t need these files when removing the Remaining Files. Deleting certain files without removing the app can cause malfunctions.

Opening preference panes

Preference panes are plug-ins that allow a user to set configurations for applications or preferences for the system to provide a graphical user interface. Some third-party apps may be downloaded as preference panes, for example Flash Player, or they may create preference panes the same way MySQL or Wacom drivers do.

App Cleaner & Uninstaller allows you to preview and remove all the preference panes on your Mac installed by third-party apps. You can find preference panes in the Extensions section.
