Uninstalling programs and applications from a computer is quite common and rather straightforward. Both Windows and Mac have built-in utilities that help in uninstalling apps that are no longer used or required. However, often uninstallers leave behind traces of programs in the form of preference files, support documents, log files, etc. These files are created when their respective apps are in use but they’re not automatically removed from the system when you uninstall their apps. Collectively, such files are known as “application leftovers” and though they don’t harm the system in any way, such files do eat up disk space and eventually contribute in slowing it down.

When you free up Mac disk space to optimize system performance, removing or deleting such leftovers is also essential. Here are some ways by which you can easily delete Mac leftover files.

Applications on macOS are self-contained packages which can be uninstalled through a simple drag-and-drop operation to the Trash. Though this works for most programs, some applications include uninstallers within them which can be invoked by clicking on a ‘Customize’ button that appears during the install process. To find and remove Mac leftover files, follow the steps below:

  1. Go to the /Home/Library/Preferences/ folder, find leftover preference files of apps that you’ve already uninstalled, and delete them manually
  2. Go to the /Home/Library/Applications Support/ folder, find any folders and components of removed apps, and delete them. Delete leftover Application Support folders too.
  3. One by one, go to the /Library/StartupItems/ and /Home/Library/StartupItems/ folders, look for leftover startup items, and remove them.
  4. Go to System Preferences -> Accounts -> Login Items and find the item in the list for the application you want to remove. Then click on the “-” button to delete it from the list.
  5. One by one go to the /Library/LaunchAgents/ or /Library/LaunchDaemons/ or /Home/Library/LaunchAgents/ folders, look for leftover startup daemons or agents, and delete them.
  6. Go to the /Library/Receipts/ folder, find any files that have ‘.pkg’ extension, and delete them. These files are used by OS X to determine if certain apps are already installed.
  7. To find and remove any other leftover files, conduct a Finder search using the application name or the developer name as the search term. Delete any resultant files that you find.

Delete files from a previous Adobe application installation

Mac Delete File

To delete files from a previous Adobe application installation, do the following:

  1. If the Adobe application folder exists, drag it to Trash. By default, the folders are located in the Applications folder on the hard disk.

  2. Drag the preferences folder to Trash from the Users/[User]/Library/Preferences folder. (For example, drag the Acrobat folder to Trash.)


    The user Library folder is hidden by default in Mac OS X 10.7 and later releases. To access files in the hidden library folder, see How to access hidden user library files.

  3. Drag the application PLIST file, located in the Users/[User]/Library/Preferences folder, to Trash. Skip this step if the Adobe application doesn't include a PLIST file.

  4. If you don't have other Adobe applications installed on your computer, drag each of the Adobe folders to Trash from the following locations:

    • Users/[User]/Library/Application Support
    • Library/Application Support
  5. Empty Trash. If you receive an error message while trying to empty Trash, see the next section.

If you receive a message that items are locked and cannot be deleted, press Option and then empty Trash.

If you still receive a message that the item is in use, do one of the following:

Mac Delete Key

  • Quit the app that you were using with the file and then empty Trash.
  • Restart your Mac and then empty Trash.
  • Start your Mac in safe mode by holding down the Shift key while your Mac starts up. Then empty Trash and restart your Mac normally. For more information, see Use safe mode to isolate issues with your Mac.
