Know your Mac in real time. Clean it in one click.

One app for your whole Mac

MacZen is built natively with Swift and SwiftUI — it lives in your menu bar, ready at a moment's notice. No spammy pop-ups, no accounts, no uploads.

Keep an eye on CPU / GPU / memory / disk / temperature / fan / network in real time; deep-clean app caches, dev leftovers and log junk in one click; visualize disk usage with treemap analysis.

Six capabilities

• System monitoring — CPU / GPU / memory / disk / temperature / fan / network / battery in real time, with history curves, pressure levels and instant alerts
• Deep cleaning — scan app caches, dev leftovers and log junk; moves to Trash by default, permanent delete needs a second confirmation
• Disk analysis — treemap visualization + Finder-style multi-column browsing; right-click to open in Finder
• App management — login items, leftover scans for uninstalled apps, per-app disk usage
• Tuning — refresh rates, menu-bar metrics, battery care thresholds, AirPods battery alerts; every detail is customizable
• Menu-bar HUD + desktop widgets — two-line live metrics in the menu bar, an expandable HUD panel, and floating desktop widgets

Your Mac. Your call.

Everything moves to Trash by default and is always recoverable; permanent deletion requires explicit confirmation. Free, no in-app purchases, no tracking — your data never leaves your Mac.
