Your Mac's hard drive is full ... again. What's taking up all that space? Endless applications promise to answer this question and help you free up space, most with a subscription. I've tested many over the years, and few are easier to recommend than Purge.

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.
