Temporary files are not needed on the system. Just like duplicate files, they take up free space and litter the OS without having a real function. To do so, you should also try using a professional Mac optimization tool like those listed above.

Empty Trash Cans.

Windows Recycle Bin = Mac Trash. Thus, if you remove the application by dragging it to Trash, it doesn’t mean that it’s gone and that it doesn’t take up free disk’s space. The apps are stored in Trash for a long time in case you decide to restore them one day.

Therefore, to increase free space on your hard disk, empty Trash regularly.

NOTE: Mac OS has several Trash cans, which is why emptying one is not sufficient.

  • To empty Trash where files removed from finder are kept, you have to click Ctrl + click or right-click on the Trash and select Empty Trash.
  • If you delete media files from within iPhoto, iMovie, and Mail, you have to clean up their Trash cans separately. For that, open a particular applicationm find its Trash, hit Ctrl + click, and select Empty Trash.

Uninstall Apps

Each app on your Mac takes up a certain amount of space depending on its difficulty and functionality. However, each application that is not used for more than half of the year should be removed. To uninstall any program on Mac OS, you have to:

  • Open Finder – select Applications;
  • Find the application that you no longer need, click on it, hold for a moment, and drag to Trash.
  • However, to uninstall a program completely, it’s a must to open these folders and remove file leftovers from there:

       /Library/Application Support/
