When your Mac’s drive fills up, the usual advice is to buy yet another disk-cleaning subscription. Purge takes the opposite approach: it is a free Mac cleanup tool with no ads or upsells, and it shows exactly what is eating your storage before you decide what to remove.
What Purge Finds and Why It Matters
Purge is open source and built around lists of files that are known to be safe to clear. Just as important, it maintains a separate list of items it will never touch, including critical system files and your personal documents. Anything it removes goes to the Trash rather than being erased immediately, so a mistaken deletion can be undone.
Macs accumulate clutter in predictable places. Caches are files saved to speed up apps and websites, but they can outlive their usefulness. Apps you uninstalled long ago can also leave settings and cached data behind, silently consuming space. Purge is designed to surface both kinds of leftovers.
A Section-by-Section Cleanup

After installation, Purge presents a breakdown of what is occupying your drive. A Clean Safe Items button can handle the basics automatically, but going through the individual tools gives you more control.
Caches and Screen Savers
The cache section lists files that are safe to purge periodically. It also includes Apple’s Aerial screen savers, which are high-quality videos that can take up significant space. If you do not use a screen saver, removing them is an easy win.
Developer Tools
Most people can skip the Dev Tools section, but Homebrew users should pay attention. It offers a straightforward way to delete cached installation files that are no longer needed.
Large Files
A dedicated view shows only the largest files on your computer, typically videos or other media. These are often items you forgot you downloaded, and moving them elsewhere can recover a substantial amount of space.
App Uninstallation and Leftovers
Purge’s uninstaller removes not just the application but also its associated settings, caches, and downloaded data. Dragging an app to the Trash in Finder does not do this, which explains why uninstalled programs can leave files behind. A separate tool lists data from apps that are already gone; in testing, this amounted to several gigabytes of wasted space.
The Apple Intelligence Option
Recent versions of macOS ship with offline AI models that power notification summaries, writing suggestions, and the AI-driven Siri. If you do not use these features, freeing that space is not as simple as flipping a switch. In macOS 27, Apple removed the toggle that let users disable the features entirely.
Purge includes a tool that lists installed Apple Intelligence models and deletes them with a single button. It also prevents macOS from reinstalling them, which could free more than 10 GB. That option is there for people who want it, while the rest of Purge’s tools remain useful even if you keep Apple’s AI features.
Why It Stands Out
Purge is not the only app that promises to clean your Mac, but it avoids the subscription model and advertising that define many alternatives. It gives you a clear view of your storage and a set of targeted actions, from clearing caches to removing forgotten large files. For anyone tired of paying for disk cleaners, it is a practical alternative worth keeping around.
