5 Ways to Delete App Data, Cache, and Leftover Files on Mac

Most Mac users delete an app directly from Launchpad or by moving its icon to the trash and emptying the bin. While both are normal ways to remove an app, it may clutter your Mac with leftovers such as app data, caches, software logs, and other unwanted files, resulting in Mac running slow or apps behaving erratically. Therefore, here’s how you can find and delete the app data, cache, and other leftover files on your Mac computer.

Delete App Data, Cache, and Leftover Files on Mac

What Are App Leftover Files on Mac?

When you install an app on your Mac, it distributes and stores many files throughout your computer. This includes application cache, saved data, application support or preference files, and other data. When you uninstall an app directly from the Launchpad or Finder, it just removes the app and not this data.

Over time, these unwanted leftover files may slow down your Mac or cause issues like the app not opening or crashing when you tap them. And hence, at times, it becomes important to remove them.

App Cache Clutter Files on Mac

For example, the Rock app on my Mac stopped opening after updates. Uninstalling and reinstalling the app didn’t help. It was only when I manually deleted the app’s residual files and reinstalled it after which it started functioning normally.


Yes, while these files remain after uninstalling the app, it is possible to remove them. And here are some of the best ways to not only delete app data and leftover files but also to completely uninstall an app along with its cache on Mac. Read on.

How to Delete App Data and Other Leftover Files on Mac?

Mac allows you to manually delete an app data or cache from the Finder. Besides, you can also use free third-party utilities to declutter your machine. Check all the methods in detail below.

  • ~/Library/Preferences/: contains your preference files
  • ~/Library/Cookies/: contains cookies stored by apps
