DaisyDisk
DaisyDisk is a macOS disk space analyzer that scans drives and folders so you can see what is using storage and remove large, unneeded files.
What is DaisyDisk?
DaisyDisk is a native macOS utility for finding what is taking up space on your Mac and other connected storage. It helps people quickly inspect internal drives, external disks, network volumes, and selected folders with a visual storage map that makes large files and space-heavy areas easier to spot. The app is useful for routine storage management, troubleshooting low-disk-space warnings, and understanding categories such as hidden or purgeable space. It also supports file preview during review, scanning specific folders, and scanning with elevated access when you need visibility into restricted locations. DaisyDisk is published by Software Ambience Corp. and is designed for users who want a focused disk analysis tool instead of an all-in-one system cleaner.
Key features
- Scan whole disks or individual folders to measure storage usage
- View disk contents as an interactive visual map to spot large files quickly
- Preview files before removing them so you can confirm what they are
- Analyze internal, external, network, and virtual disks from one interface
- Show hidden, purgeable, and restricted space when the needed access is granted
- Collect selected items for review before deleting them

Safety overview
Status: Mostly safe
DaisyDisk is a well-known disk analysis utility for macOS, and its requests for Full Disk Access or administrator-assisted scanning are consistent with showing storage usage in protected locations. Those permissions can expose more of your files to the app, so grant them only if you use the advanced scanning features and only from the installed DaisyDisk app. Be careful when deleting items it finds: the app helps you locate large files, but removing important data can still affect your documents, apps, or backups.
Recommendation: Keep DaisyDisk if you use it to manage storage or investigate low disk space on your Mac. If you no longer use it, you can remove it like other Mac apps, but do a final check before deleting files you collected for cleanup so you do not remove something you still need.
