The overnight problem

An unexpected sleep kills your run instantly.

Close the lid and macOS sleeps — your training job, your agent, your build, gone. Keep it open and you sweat over heat and battery. ZZZoff keeps the Mac running with the lid shut and watches it so it never cooks itself or dies.

What you get

Awake, safe, and watched.

Lid-closed wakefulness

Runs with the lid fully shut — no external display, no dummy dongle. The one thing caffeinate & Amphetamine can’t do.

Thermal kill-switch

Watches the chip and sleeps the Mac before it overheats. Run hard, sleep safe.

Battery floor

On battery? It stops below your threshold so you never wake up to a dead Mac.

One-tap Telegram

Scan a QR, tap Start — no bot setup, no copy-paste. A DM the moment something needs you.

Offline watchdog

A cloud sentinel pings your Mac. If it drops off the net mid-run, you hear about it — wherever you are.

Notch & session stats

Clawd lives in the notch with a live timer, and ZZZoff tracks every run like a fitness app.

Stay in the loop

Walk away. Get pinged if it matters.

Battery low, Mac overheating, timer ended, or your laptop fell off the internet — Clawd DMs you on Telegram with a friendly nudge. Connect in one tap.

No surprises

Transparent by design.

🔏 Signed & scoped

Developer-ID signed. The one-time admin grant is scoped to a single pmset call — nothing else.

👀 It never lies

The menu-bar state reads the real system flag, so the icon always reflects what your Mac is actually doing.

🧊 Safety first

Thermal & battery guards are conservative by default — ZZZoff would rather sleep than risk your Mac.

Let it run. Clawd’s got the night shift.

Download ZZZoff and never lose an overnight run to a sleeping Mac again.
