  • Then, choose About this Mac in the drop-down menu.
  • Now, click on the Storage tab, then click on Manage.


A window appears to the right with the following:

  • Store in iCloud
  • Optimize Storage
  • Empty Trash Automatically
  • Reduce Clutter

Optimised Storage On Mac

Use any of the tools in the window to get more storage on your Mac. Here’s how to use each of the options:

Store in iCloud

When you click the Store in iCloud option, it allows you to store files from the Desktop and Documents folders in iCloud Drive. Furthermore, it also allows you to Store photos and videos in the iCloud Photo Library.

Optimize Storage

With this option, you can save movies as well as TV shows and email attachments. You may re-download the files at a later date if you so desire. By clicking the option it asks if it is ok to go ahead and removed watched movies and shows from your Mac.

Empty Trash

As the name suggests, this option allows you to automatically empty files in the trash after a set period of time (30 days).

Reduce Clutter

With Reduce Clutter, you have to manually delete files. When you click Review Files button in the Reduce Clutter section, you have to select the file categories in the sidebar you wish to review and remove. Use the feature to delete old downloads to help free up space filled by Other Storage.
