Mac disk visibility

Finally see what's inside "Other."

Scout digs through developer caches, duplicates and the system data macOS won't explain — free up 40+ GB and know exactly what each one is before anything is removed.

ways to look at what it finds

How it works

Three steps. You make every call.

Lucid Disk never removes anything on its own. It scans, explains, and waits for you.

STEP 01

Scan every corner, in seconds

Checks the places Finder hides — whatever kind of Mac you use it for.

Devs: Xcode caches, node_modules, Docker

Everyone else: browser data, old backups

STEP 02

Plain language, not cryptic paths

Every result says what it is and whether it'll come back on its own.

e.g. "CocoaPods cache — rebuilds on install"

e.g. "iPhone backup — device disconnected"

STEP 03

You select. Lucid Disk deletes it.

Nothing is chosen for you, and nothing is deleted until you confirm.

Permanent: removed outright, not moved to the Trash

What it finds

Built for what actually fills up a Mac

"Other" isn't one thing — it's every one of these, lumped together with no explanation. Categories only appear when the scan actually finds something in them, so you never scroll past empty rows.

Browser, Mail & Messages

Safari and Chrome caches, Mail's locally-stored attachments, and years of photos, videos and GIFs sitting in Messages.

Commonly 10–30 GB combined, unnoticed until you look

Duplicates & old backups

True content-hash duplicate detection, not filename guessing — plus local iPhone and iPad backups, including from devices you no longer own.

Old backups alone run 10–30 GB each

Developer caches

Xcode DerivedData, CocoaPods, npm, Homebrew and node_modules across every project you've cloned. Docker usage is reported, never touched.

Typically 20–60 GB on an active dev machine

Runs entirely on your Mac.

Scanning, hashing and duplicate matching all happen locally. There is nothing to sync and no server of ours to talk to — the one exception is checking your license key.

No account to create — a license key is the whole setup
Full Disk Access is used to read and report only, never to act without your selection
Deletion is permanent and unrecoverable — Lucid Disk says so plainly before it acts
Protected system paths are re-checked immediately before every delete, and refused
No analytics, no tracking pixels, no telemetry beyond crash reporting

FAQ

Questions people ask

What is the "Other" or "System Data" category macOS shows me?

Apple's storage screen lumps caches, logs, local backups and anything that doesn't fit its other categories into one unexplained number. Lucid Disk is built specifically to open that up and show you what's actually inside it.

Can it delete something I still need?

Not on its own. Nothing is selected for you except caches that rebuild themselves, and nothing is removed until you confirm. Deletion is permanent, so the app tells you that before it acts rather than after — and protected system paths are refused outright.

Why two views instead of one dashboard?

Simple gives a clear yes/no per category for people who just want the space back. Explore maps the whole disk when the categories aren't enough. Both read the same scan — you're never choosing between two different truths.

Does it need to be online?

Only to activate your license the first time. Scanning and browsing results always work offline after that.

How many Macs does one license cover?

Two. The key is needed before the first scan — there is no free scan mode — and it can be deactivated on one Mac and moved to another.
