UndigHonest APFS sizes
Clones share their data, so deleting one frees almost nothing. Undig detects them and shows what you will really recover.

Finally, where your storage went.
macOS hides most of your disk behind “System Data”. Undig measures the sealed system volume, hidden APFS volumes, purgeable space, snapshots and the Trash, and explains each one in plain language.

Questions
Good to know.
Is it safe?
Everything Undig removes goes to the Trash first and is recorded in a Journal, so you can restore it until you empty the Trash. When Undig is unsure, nothing is ticked by default, and every row explains what it is.
Does it send my data anywhere?
No. Undig runs entirely on your Mac. There is no account and no analytics, and license keys are verified offline.
Why does it ask for Full Disk Access?
macOS hides the Trash and some folders from apps. Without access Undig still works, but it cannot see or empty the Trash.
Does Autopilot delete things on its own?
Autopilot first sets safe items aside, and you can undo that. Only after the safety window you chose does it free for good, and only what Undig itself set aside. It is off by default and part of Undig Pro.
What happens after the free 2 GB?
You can still scan and see everything. Cleaning more needs Undig Pro, a single payment.
Which Macs does it run on?
Any Mac with macOS 14 or later, Apple silicon or Intel.
