Macometr starts in the menu bar, at the top right of your screen, without a Dock icon: look for small CPU, GPU and RAM readings. Click them to open the panel. Open Usage History with the chart button at the bottom of the panel, or from the gear menu → Usage History…. If you don't see the readings, your menu bar may be full: on MacBooks with a notch, macOS hides items that don't fit. Quit another menu bar app, or hold ⌘ and drag Macometr further right.
Open the panel and click the gear icon. There you can open Usage History, pause or resume Record Usage History, turn Include app usage on or off, and choose which values appear in the menu bar, the update interval (1, 2 or 5 seconds), mini gauges, notifications and Launch at Login.
Record Usage History is on by default, so Macometr records system readings while it runs. The first figures appear after a minute or two. You can pause recording at any time in the Usage History window or the gear menu; pausing keeps what's already recorded. Leave Macometr running during normal work: the report grows from real observations and doesn't fill in time while your Mac sleeps or the app is closed.
Macometr can only show what it has recorded. A new installation starts with an empty history and keeps up to 30 local calendar days as it goes. The report always shows how much time was recorded, and a day without readings appears as a gap, not as zero.
It can show repeated conditions in your recorded workload, such as memory pressure or long busy stretches. It doesn't benchmark another machine or reliably predict how much faster an upgrade would be.
Turn on Include app usage, in the Usage History window or the gear menu. It's off by default and records only while Record Usage History is on. After about a minute, the report shows two lists, Memory and CPU, both shown together, each with up to five apps. Use the menu next to "Apps Using Resources" to switch both lists between the whole period and the day selected in the Day bar at the bottom of the window.
The Memory list is ordered by sustained footprint over time. The value shown is the average footprint while the app was observed. An app using a moderate amount for hours can rank above one that used more memory briefly. This isn't a memory-leak diagnosis.
CPU time adds work across processor cores. An app keeping several cores busy builds up more CPU time than the wall-clock time that passed. It isn't screen time or a productivity score.
Macometr couldn't observe every relevant helper process or interval for that app and metric. Missing readings aren't counted as zero; apps that couldn't be read at all are shown as unavailable. Use the observed time shown under each value when you interpret it.
No. App history covers CPU and memory only. While the panel is open, it can list a few apps under "Reported app activity": apps the graphics driver's counters report as active. Those counters identify some active apps, not an exact or complete share of GPU use, so the panel shows names only, and the list isn't stored. If the GPU is busy and no app is reported, the panel says "No app activity identified by these counters". That doesn't tell you what the work is.
Green means everything is fine. Orange means a sustained heavy load (at least a quarter of your cores busy for two minutes, or the GPU above 90% for two minutes) or elevated memory pressure. Red means it needs attention: most of your cores busy for two minutes, a heavy load lasting five minutes on battery, or critical memory pressure. In the menu bar, values stay white until something needs attention.
Your Mac has been working hard for a while. Often that's expected (a video export, a build); sometimes it's something you didn't start. Click Activity Monitor in Macometr's panel, sort by "% CPU", and look for an app you aren't using that sits near the top. You can quit it there.
The two apps sample at different moments and intervals, can average differently, and may define or group values differently (for example how helper processes are counted). Similar trends matter more than matching numbers. Setting Activity Monitor's View → Update Frequency close to Macometr's interval makes the two easier to compare.
The percentage shows how full your RAM is. When it's full, macOS compresses memory and then uses swap on your SSD; that shows up as memory pressure turning orange or red, not as a number above 100%. Occupied swap by itself doesn't mean your Mac is struggling right now; pressure tells you more.
No. Macometr doesn't display temperatures or fan speeds. It shows the thermal state macOS reports (Normal, Fair, Serious, Critical) and adds a thermometer to the menu bar when that state is Serious or Critical.
Turn on "Notify If Draining Battery" to get one notification when something keeps your Mac busy while it's on battery. If you declined the permission, enable it in System Settings → Notifications → Macometr.
On your Mac, inside Macometr's private sandbox container. Macometr has no network access and doesn't upload or sync it. Copy Report puts a text summary on your clipboard only when you click it, and you decide where to paste or share it; app names are left out unless you check "Include app names in copied report". See the Privacy Policy for details.
The history is stored separately from the app, in Macometr's private container, and is meant to be kept when Macometr is updated in place. To remove history on purpose, use Delete History… at the bottom of the Usage History window.
If you want your recorded history gone too, first open Usage History and choose Delete History…. Then turn off Launch at Login in the gear menu, click Quit at the bottom of the panel and move Macometr from the Applications folder to the Trash. Moving the app to the Trash doesn't necessarily remove its private container, so deleting the history first is the reliable way.
A Mac with Apple silicon running macOS 26 or later.
