1. Utilize Apple's native storage optimizer

Here's how to uninstall apps on Mac:

  1. Open a new Finder window and go to Applications.
  2. Take a look at which apps you no longer use and drag them to your Trash can.
  3. Empty your Trash.
  4. Now, search for leftover files by opening Finder > Go > Go to Folder; look in the following locations for any files containing the name of the app you just removed, send them to your
  5. Trash, and empty it again afterward:

    ~/Library/Application Support
    ~/Library/Caches
    ~/Library/Internet Plug-Ins/
     ~/Library/
     ~/Library/Preferences/
    ~/Library/Application Support/CrashReporter/

5. Utilize external or cloud storage

If you've got thousands of videos and photos on your Mac, moving these to either an external storage device or cloud service like iCloud, Google Drive, or Dropbox is a good idea.

Offloading your media files to external or cloud storage can free up large amounts of space on your Mac, which in turn can improve its performance and speed.

6. Delete your large and old files

How old is your device? Chances are, you've got a lot of large or old and unwanted files stored in the depths of its forgotten storage. The problem is that not many of us have time to go scouring through all the folders and hiding places.

Well, the good news is, you don't have to. Use the tool we discussed earlier, CleanMyMac X, to scan, find, and categorize all your files by size, type, and, amazingly, last accessed date; here's how:

  1. Open the app again.
  2. Select Large & Old Files > Scan.
  3. Browse the categories, select unwanted files, and click Remove.

7. Desktop and Downloads cleanup

Finally, don't forget to clear up your Desktop and Downloads folder. Both of these locations are well-known for harboring useless clutter.

If you use Stacks, it's easy to forget what's hiding on your Desktop. Right-click anywhere on your Desktop and press Use Stacks to reveal what's lurking.
