“Activity Monitor shows you numbers. The Insights Engine tells you what they mean.”
// New in 1.2.2 · Direct only · macOS 26 Tahoe

Ask your Mac,
anything.

Questions in plain English. Answered entirely on-device by Apple Intelligence — nothing leaves your Mac. No API keys, no cloud, no telemetry.

— You “How high did CPU go yesterday?”
— You “Which apps used the most energy today?”
— You “What’s been writing to disk most?”
— You “Did Xcode slow me down today?”
Ask Insights grounds every answer in real data from your Mac’s history — the same database the Insights Engine has been maintaining all along. The model translates your question into the right lookup and summarizes the result; visible tool-call chips show you exactly which data the answer was built from. If there’s no matching data, it tells you — it won’t invent a number.
Requires macOS 26 Tahoe on an Apple-Intelligence-eligible Mac with Apple Intelligence enabled in System Settings. On older macOS the rest of MacPulse works exactly as before — the feature simply doesn’t appear. Not available in the Mac App Store edition.

// 06 FAQ

Things people
ask first.

Quick answers about Mac system monitoring, the Insights Engine, and how MacPulse compares to Activity Monitor and iStat Menus. More at ~/faq.

Q. Is Activity Monitor enough on Mac?
Activity Monitor shows what’s running right now, but it doesn’t keep history, doesn’t surface trends, doesn’t read SMC thermal sensors, and doesn’t explain what its numbers mean. MacPulse adds a 30-day SQLite history with intelligent downsampling, a plain-English Insights Engine, performance session recording at 1-second resolution, fan curves, and menu bar sparklines — covering everything Activity Monitor leaves on the table.
Q. What is the best iStat Menus alternative for Mac?
MacPulse is the modern iStat Menus alternative for macOS. iStat Menus 7 is a polished, mature menu-bar-first system monitor at $11.99 one-time (not subscription) with 28-day graphs. MacPulse adds a unique rule-based Insights Engine that explains performance patterns in plain English, performance session recording with CSV export, fan curves and thermal presets, and is available on the Mac App Store, Setapp, and direct (€14.99 Personal / €49.99 Family). If you want a menu-bar widget kit and don’t need analysis, iStat Menus is excellent. If you want your Mac to explain itself, pick MacPulse. Full head-to-head →
Q. What does memory pressure mean on Mac?
Memory pressure is macOS’s signal of how hard it’s working to keep your apps in RAM. Green means plenty of free memory; yellow means macOS is starting to compress and swap; red means active swapping to disk that hurts performance. MacPulse tracks compression ratios over time, flags sustained pressure events, and shows week-over-week trends — so you know whether to add RAM, close apps, or just ignore it.
Q. Why is my Mac slow?
Common causes: thermal throttling (CPU dropping speed because it’s hot), memory pressure (macOS swapping to SSD), background processes hogging CPU, Spotlight indexing, or a failing SSD. MacPulse’s Insights Engine flags all of these in plain English — for example: “Thermal throttling detected for 3 minutes during compile” or “Memory pressure reached warning 4 times today, 78% of samples above 85%” — so you can act instead of guess.
Q. How do I check Mac performance?
Open Activity Monitor for a real-time snapshot, but for sustained checking install a dedicated system monitor. MacPulse runs in the menu bar with sparkline charts, records 30-day history, lets you start a performance session at 1-second resolution to capture a specific event (compile, render, gaming), and the Insights Engine reads the data and explains what’s happening. Free 14-day trial.
Q. Does MacPulse work on Apple Silicon?
Yes — universal binary, native on Apple Silicon (M1, M2, M3, M4) and Intel. macOS 14 Sonoma or later. CPU monitoring shows P-core and E-core breakdown on Apple Silicon. The Ask Insights on-device chat (via Apple Intelligence) requires macOS 26+ and is Direct-edition only.
Q. Does MacPulse have a menu bar mode?
Yes. MacPulse can run as a full app, as a menu bar status item with sparkline charts, or both at once. The menu bar mode shows live CPU, memory, network, GPU, and thermal at a glance — click to see the full popover with Bluetooth batteries, top processes, and quick controls.
Q. Is MacPulse a subscription?
No. MacPulse is a one-time purchase: €14.99 Personal (1 Mac) or €49.99 Family (5 Macs). Lifetime updates included. Also available on the Mac App Store (as “System Insights”) for €14.99 one-time, and on Setapp as part of your subscription.
