How to Free up Space on Mac

If you've checked your storage on Mac and you're worried you're running out of space, there are many ways to clear space on your Mac. Here's a quick look at some of the simplest methods.

  • Empty the Trash. Every time you delete a file, it goes into your Trash can but isn't permanently deleted until you empty it. Make sure to empty it often.
  • Remove unwanted apps. If you have many apps you rarely use, drag and drop them into your Trash can to remove them and free up space.
  • Move some files to the Cloud. Via About My Mac > Storage, you can manage your files and move many of them to iCloud. That includes photos which can take up a lot of space on your hard drive. 
  • Check for large files. Check to see if you've downloaded large music or movie files and delete them if you rarely use them.
