1. Start with the item you’re curious about.
For a question about Swap, start with what it is, why it exists, and what changes usually mean. Then, when useful, relate that explanation to your current readings.
SanaryBuild MeterSBM · macOS System Monitor / System Health UtilitySee it. Ask it.
Understand it.
Your Mac’s activity, at a glance. A closer look when you need it. An explanation when you want one. A system monitor that helps you make sense of what you see.
A quick look at your Mac, without leaving your flow.
01 / GLANCE
Keep your work in view.
And your Mac in sight.
A busy moment or a persistent slowdown? The menu bar gives you a sense of your Mac’s activity through icons and color. Keep the numbers visible, or hide them for a quieter view.
02 / GLASS
A little more detail.
Just one click away.
You don’t always need a full dashboard. Click a meter to open Glass: current readings, useful context, and leading processes for that item. Click another meter to switch, without closing the view first.
Prefer to dismiss Glass by clicking outside it? You can choose that behavior in Settings.
03 / DETAIL
Go beyond the current reading.
When you want to investigate, move from Glass into Detail. Start with the current state, look at contributing factors, follow changes over time, and explore deeper system information.

AdvancedDeeper system information
Explore CPU, Memory, GPU, Network, Disk, PCC, and Thermal. Power appears as supporting system information, rather than a separate menu bar meter.
HISTORY / SYSTEM HEALTH
A momentary spike?
Or a lasting change?
Readings make more sense with context. Follow activity through History, then check System Health for an assessment based on observed data. SBM applies defined rules to determine health.
SBM measures and judges. AI explains. You decide.
Health assessment is not delegated to AI. SBM handles measurement and deterministic health judgments; AI helps explain the information so you can decide what to do.

04 / ASK ABOUT THIS
Don’t know what it means?
Ask right there.
Right-click a value, label, or process in Glass or the Dashboard and choose “Ask about this.” Your question starts with the item you’re looking at, without copying readings into a separate chat.
2. Understand the meaning behind the reading.
Get context, beyond a restatement of the numbers. Process explanations are designed to acknowledge what cannot be verified, rather than invent a purpose from a name.
Explanations powered by Private Cloud Compute.
When you ask, Apple’s Private Cloud Compute (PCC) uses the diagnostic context needed to explain what you’re seeing. Measurement and health judgments do not depend on AI. If PCC is unavailable, the app shows the reason.

ACTIVITY COLOR
Icon = What it is.
Color = How active it is.
CPU isn’t assigned blue, nor Memory purple. Activity colors change continuously with how active a metric is, so you can get a sense of your Mac’s activity even with the numbers hidden.
- White
- Blue
- Green
- Yellow
- Pink
- Red
Red does not necessarily mean something is wrong. Activity Color and health judgments are separate. PCC and Thermal status colors also carry meanings distinct from activity.
PRIVACY / READ-ONLY
Observe with confidence.
Stay in control.
Read-only by design
SBM does not terminate processes, change Mac settings, or control fans. It gives you information to help you make your own decisions.
App Sandbox
SBM maintains App Sandbox. Process information is limited to what can be measured for your own user; it does not have unrestricted access to every process on your Mac.
Ask when you need context
AI serves as an explanation layer, using relevant diagnostic information when you ask. System measurement and health assessment remain SBM’s responsibility.
