01
Visibility
Live system status, health scores out of 100, disk maps, and drive & battery vitals — the state of your machine, at a glance.
Native macOS control panel
Mission control for your Mac dev environment.
Homebrew, pip, virtual environments, a broken toolchain, disk bloat, drive and battery health — even moving your whole setup to a new Mac. Catalyst turns every terminal chore into a few safe, reversible clicks. No incantations to memorize.
The terminal tax
Doable from the command line — if you remember the exact incantations, and get every flag right.
- python3 -m venv .venv && source .venv/bin/activate
- brew install --cask … && brew cleanup
- pip install … --break-system-packages
- lsof -i :3000 | awk 'NR>1 {print $2}' | xargs kill
- smartctl -a /dev/disk0 | grep -i health
Each is a small toll. Catalyst pays it for you — wrapping all of it in a clean, native interface, and never doing anything destructive or system-altering without explicit, informed consent.
02
Control
One-click install, uninstall, and update across Homebrew and pip — package management without the flag-guessing.
03
Guided maintenance
A doctor that scans, scores, and auto-fixes environment problems, plus sweepers that reclaim disk — recoverably.
One loop, every action
Every feature is a variation on the same safe loop.
The app's real value and real risk both live in one step — running shell commands on your behalf. So every action, everywhere, follows the same path.
- 01 A click Your intent — nothing typed.
- 02 Sanitize Names & paths pass an allowlist.
- 03 Execute off-main Run on a background tier.
- 04 Check exit code Success is proven, not scraped.
- 05 Re-sync The whole app refreshes.
The one nobody else has
Move your entire dev environment to a new Mac — in one file.
Snapshot & Migrate captures Homebrew, Python and every pip package, your full , SmartShortcuts, git identity and tracked venv projects into a single portable .catalystsnapshot. Open it on a clean Mac and Catalyst rebuilds the setup for you — item by item, idempotent and resumable.
- Secrets are never exported — keys and tokens are scrubbed at capture, and listed so you can reset them.
- Your new Mac's is backed up before anything is written, then syntax-checked.
- Already-installed items are skipped. Stop and resume any time — nothing runs twice.

OpenConsent, by design
Catalyst will never break your system Python without you choosing to — in an informed, transparent, reversible way. Deletions go to the Trash. Private keys are never shown. Success is judged on exit codes, never on scraped text.How Catalyst keeps you safe
