This Totally Free App Can Free Up Space on Your Mac

This totally free, open source app gives you a quick breakdown of what's taking up space on your hard drive and offers a few specific ways to free it up. Even better: There are no ads or upsells. Purge can even delete Apple Intelligence's offline models from macOS 27, which could free up over 10 GB.

But even if you want to keep Apple's AI features, you can still clear up plenty of space. Your Mac, like any computer, tends to build up clutter over time. Sure, you might have forgotten about the games, images, and videos you downloaded, but caches also take up space. These are files downloaded and saved to speed things up, which can be useful.
