SYS / NATIVE MACOS VITALS MONITOR

Slow? Hot? Fans blasting? Find the culprit.

Hundreds of processes are running on your Mac right now. KernPulse watches every one of them from your menu bar—and when something misbehaves, it names the app, shows the numbers, and hands the decision to you.

01 / SEE → UNDERSTAND → ACT

From “something’s wrong”
to “it was Safari.”

Numbers tell you something is wrong. KernPulse tells you what, why, and what you can do about it—in one panel, three steps.

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

You call the shots

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

No magic buttons.
Real answers instead.

A “Free RAM” button makes a number look better for a minute—then your Mac pays it back with interest. KernPulse refuses to sell placebos: every finding names a process with evidence, and nothing happens without your say-so.

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.

05 / CLEAR BOUNDARIES

Straight questions.
Straight answers.

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.
