MacFossils helps you find leftover files from apps you have already uninstalled on your Mac. These leftover files take up space and can slow your system over time. This simple tool scans your Mac and shows you what files you can safely remove to free up disk space. It works quietly in the background and gives you control over what gets deleted.
MacFossils focuses on spotting unused leftover files from various applications. It also works well with Apple Silicon Macs and recent macOS versions like Sonoma and Monterey.
When you uninstall software, some files may remain on your Mac without your knowledge. These files include caches, preferences, and support files. Over time, these remnants build up and consume valuable disk space.
MacFossils makes cleaning these files easy. It helps you:
- Identify leftover files from uninstalled apps.
- Remove unnecessary data safely.
- Improve system performance by freeing disk space.
- Maintain your Mac with low effort.
Before using MacFossils, check these system requirements to ensure compatibility:
- macOS 10.14 Mojave or later (including macOS Sonoma)
- Any Intel or Apple Silicon (M1, M2) Mac
- Minimum 100 MB free disk space for the app
- Administrator privileges to remove some system files
MacFossils runs well on most Macs made after 2015. You do not need any other software to use it.

Click the "Start Scan" button in the app. MacFossils will scan your hard drive to find leftover files from apps you no longer have.
The scan may take several minutes depending on your disk size.
When the scan finishes, MacFossils shows a list of leftover app files grouped by app name or type.
You can look through the list to see what files are found. MacFossils will tell you the size of each file or folder.
You choose which leftovers to remove. By default, MacFossils selects files that are safe to delete.
Uncheck any files you want to keep.
