SYS / NATIVE MACOS VITALS MONITOR

When your Mac acts up,follow the evidence.

KernPulse watches your Mac’s vital signs from the menu bar. It goes beyond CPU, memory, and temperature to explain what changed—and leaves every action in your hands.

01 / THE DECISION LOOP

Not more numbers.
A shorter path to the answer.

Status is only the starting point. KernPulse puts monitoring, attribution, and action in one path, so every action has a reason—and a boundary.

01 / SEE

See what is happening now

CPU, GPU, memory, network, disk, temperature, power, and fans come together in one menu bar panel. The 24-hour history preserves peaks and leaves honest gaps for sleep and restarts.

Live vitals and per-core load
Six history ranges
Unavailable hardware stays hidden

02 / UNDERSTAND

Understand what caused it

Insight cards appear only when there is evidence. They identify the source of memory pressure, sustained growth, idle memory hogs, and the process preventing your Mac from sleeping.

Every finding names a process and amount
No permanent wall of alerts
No guesses presented as answers

03 / ACT

Choose what happens next

Pause an app, resume it, end a process, or enable Keyboard Comfort Mode with explicit permission and safety fallbacks. Reversible actions come first; KernPulse never decides in the background for you.

App-level pause with click-to-resume
Two-stage safe termination
Fan control returns to macOS on exit

02 / EVIDENCE BEFORE ACTION

Evidence first.
Buttons second.

KernPulse does not offer a “free RAM” placebo that only makes a number look better for a moment. Every suggestion needs an explainable process, duration, or resource change; every intervention needs your confirmation or pre-authorization.

On-device reasoningMonitoring and diagnosis do not depend on the cloud.

Honest fallbackIf macOS does not expose it, KernPulse does not guess.

03 / HISTORY WITH INTEGRITY

Keep the peaks. Keep the gaps.

Long ranges preserve peaks instead of averaging away the real problem. When your Mac sleeps or restarts, the line breaks rather than inventing data that never existed.

04 / LOCAL BY DESIGN

Your system vitals
stay on your Mac.

Core monitoring and diagnosis happen on-device. The app uses native Swift and system interfaces with no third-party runtime dependencies; this website contains no analytics scripts or tracking pixels.

Cloud account: Not required
Telemetry: No third-party tracking
Background helper: Only for Comfort Mode, when enabled
Control boundary: Confirmation or pre-authorization required

05 / CLEAR BOUNDARIES

What it does.
And what it will not do.

Does monitoring require administrator access?

Normal monitoring does not. Only Keyboard Comfort Mode asks you to enable and approve a privileged helper that can raise fan speed. Turning the feature off or quitting KernPulse returns control to macOS.

Will it automatically clear memory or quit apps?

No. KernPulse has no “free RAM” button and never pauses or terminates a process without authorization. Every action is confirmed by you or allowed through a pre-authorization rule you created.

Why are temperature or GPU readings missing on some Macs?

Different Mac models expose different sensors and performance fields. KernPulse hides unavailable items or shows a dash; it never fills missing system data with estimates.
