Frequently asked questions
Filter by category to narrow things down.
Install & runIs mStat free, and do I need an account?
mStat is a free download from the Mac App Store and requires no account. It supports Apple Silicon and Intel Macs running macOS 15 or later.
Menu bar & panelHow can I show CPU usage and memory in my Mac menu bar?
Launch mStat, right-click its menu bar status item for the app menu, and open Settings. Select CPU and memory in the Menu Bar section, then choose icon + value, two-line compact or mini chart to show readings. Left-click the status item for per-core CPU load, memory capacity and memory pressure in the full panel.
Menu bar & panelCan mStat show free disk space and network speed?
Yes. Left-click the mStat menu bar status item to see main-disk usage, available space, network upload and download speeds, and peak speed in the full panel. Network readings can also stay in the menu bar; disk is not one of its four selectable metrics.
Network & privacyAre the readings on this website from my Mac?
No. The panel and settings window on the mStat website are interactive demonstrations built with web components. CPU, memory and network readings are simulated and do not access your device's system metrics. The installed mStat app reads and displays real system data locally on your Mac.
Install & runWhich systems and processors does mStat support?
macOS 15 or later, on both Apple Silicon and Intel. It is a menu bar app and never appears in the Dock.
Install & runWhere do I find mStat after installing it?
Once the app is running, look for the mStat status item on the right-hand side of the menu bar. Left-click it to open the panel, right-click for the app menu.
Install & runHow do I make it start at login?
Turn on Launch at login in Settings. If it says macOS needs your approval, click Open System Settings in the message and allow mStat under Login Items.
Menu bar & panelCan I choose what the menu bar shows?
Yes. The Menu Bar section in Settings lists CPU, memory, network and battery, each with a live reading. Pick up to three and drag the tags to set their order. There are four styles: icon only, icon + value, two-line compact and mini chart.
Menu bar & panelWhy has mStat disappeared from the menu bar?
When the menu bar is crowded, or the display has a notch, macOS hides status items that do not fit. More readings and wider styles make that more likely, and Settings warns you when the item gets wide. Choose fewer readings, or switch to the icon-only or two-line compact style.
Menu bar & panelWhy is the battery row missing on some Macs?
Macs without a built-in battery hide the battery row, and the panel lets the disk take the full width instead. On power the battery bar turns green and shows the time to full.
Menu bar & panelHow often does it refresh, and what does power saving change?
Once a second by default, whether the panel is open or not. Turn on power saving and the menu bar updates every 30 seconds while the panel is closed, which cuts CPU use further; opening the panel still snaps back to every second.
Network & privacyWhy is the public IP masked?
mStat masks the public IP by default so sharing your screen or taking a screenshot cannot expose it by accident. Click to reveal it. The local IP can be clicked to copy.
Network & privacyWhat happens when it looks up my public IP?
The app makes an HTTPS request to a public IP service, which receives your public IP and standard request metadata. mStat never uses the returned address for analytics or advertising.
Appearance & languageCan I change the appearance and language?
Appearance & Language in Settings offers System, Light and Dark, plus Simplified Chinese, Traditional Chinese, English, Japanese, Korean, German, French, Italian, Spanish and Portuguese. A language change needs a restart.
