Your Mac's health on one screen

Mac maintenance — calm, explainable, recoverable
Atlas is an open-source macOS maintenance workspace. Every action produces a plan, is itemized for review, and enters the ledger — restorable item by item within the retention window. Nothing is silently deleted.

Why Atlas
Cleaners delete files without telling you what was removed
Atlas lists every item in a plan, runs only after you confirm, and records it to the ledger
A config file gets deleted and there's nothing to find or restore
Atlas creates a restore point for each action and lets you recover item by item from the ledger (when supported)
Tools demand Full Disk Access without explaining why
Atlas requests permissions on demand, explains each one, and runs basics without Full Disk Access
Core modules
Smart Clean
Scan, review the plan, run on confirm
System caches 3.2 GB — review the breakdown before cleaning
Restore point created before run; rollback supported
File Organizer
File scattered files into place by rules
Auto-sort Downloads by type/date/project, preview then run
Moves, never deletes — and still enters the ledger
Apps
Map each app's full footprint and plan uninstall
See every related file an app leaves on disk
Lists all targets before uninstall, item by item
Ledger
A traceable timeline of every action
Plan №N · scan receipt · restore point — all numbered on the record
Every action is traceable; nothing happens silently
Permissions
Least-privilege, explained before request
Requests access only when scanning a protected location
Every permission comes with a stated purpose
How it works
Scan
Atlas reads your disk and identifies caches, logs, and leftovers to produce a plan.
Review
The plan is itemized with explanations and sizes — you decide what stays or goes.
Run
On confirm, Atlas creates a restore point and records the action to the ledger as plan №N.
Restore
Within the retention window, recover cleaned items one by one from the ledger (when supported).
Every action, on the ledger
Atlas makes trust structural: scans produce plans, runs enter the ledger, restore points are real. The number, receipt, evidence, and recovery path aren't marketing — they're things you can click.

- Why it's safe
- Evidence (path / size)
- Recovery path
Item-level restore within the retention window; some cases (e.g. snapshot-covered items) may not be supported.
Developer-friendly
Atlas recognizes dev toolchains and avoids deleting things that matter.
Toolchain-aware
Detects caches and artifacts from Homebrew, Xcode, Node.js and more, flagging each as safe or cautionary.
Project directory protection
Sees .git, node_modules, build and similar directories and excludes them by default to keep your workflow intact.
CLI integration
Ships a CLI for scripted scan and clean, ready to drop into automation.
Transparent ledger logs
Every action is recorded under its plan number with paths, sizes, and timestamps for easy auditing.
Safety
Atlas's design principles: explain before acting, recover after.
Preview before acting
Every clean shows the full target list first — there is no black-box one-click clean.
File-level backup
Cleaned files are backed up for the retention window and recoverable item by item from the ledger (when supported).
Least privilege
Atlas requests specific permissions only when needed, each with a stated purpose. Basics run without Full Disk Access.

FAQ
Is Atlas signed and notarized?
Atlas is signed with an Apple Developer ID and passes Apple's notarization. On first launch, macOS Gatekeeper verifies integrity automatically. Prerelease builds may not be notarized and require a manual right-click → Open.
What happens after installing a prerelease?
Prerelease builds may contain unfinished features or known issues and are for testing only. Because they aren't Apple-notarized, the first launch needs a right-click → Open. Don't rely on them on important machines.
Does Atlas upload my files?
No. Atlas runs entirely on-device and never collects or uploads files or personal data. Scan results and ledger entries stay local. The source code is fully open for review.
What do 'ledger' and 'recoverable' actually mean?
Before cleaning, Atlas backs up the targets to a local retention directory and records the action on the ledger under a plan number (№N) with paths, sizes, and a restore point. Within the retention window (default 30 days) you can recover cleaned items one by one from the ledger. This is file-level backup, not a system snapshot, so some cases may not be supported.
Does Atlas need Full Disk Access?
Basics run without Full Disk Access. Atlas follows least privilege — it only requests a permission when scanning a specific protected location, and explains the purpose first.
Is Atlas on the Mac App Store?
Not today. Atlas is distributed via direct download to keep full system-maintenance capability. The Mac App Store sandbox would limit core clean and restore features. A slimmed-down version may be considered later.
