If you are struggling with not enough storage and trying to make more space on your Mac, Apple helpfully outlines ways to save space and shows some mysteriously named elements taking up storage space. In macOS Ventura and later, If you click on the Apple logo > About This Mac > More Info > General > Storage Settings (or in macOS Monterey and older: Apple logo > About This Mac > Storage), you will see lots of information about what is taking up space on your Mac as well as tips to help you manage it.
Among some mysteriously named elements taking up storage space you may see the likes of System, System Data, macOS and Other and wonder if you can delete them. We address how to delete Other on a Mac in a separate article. Here we will be addressing System and System Data.

As a result, you will see examples pre- and post-Ventura. To find out more read How Apple has revamped System Preferences in macOS Ventura.
