Can a Mac App Store app automatically lock my Mac?

Yes. Peeku on the Mac App Store includes an optional screen-saver-based walk-away lock, plus private coaching, local presence signals, eye-rest nudges, and walk reminders.

What is the safest first Mac lock setting?

Set macOS to require a password immediately after sleep or screen saver. That setting makes any lock action meaningful, whether it is manual, timer-based, or automatic.

I reliably press Control-Command-Q before leaving.Manual locking is good when it is truly reliable; most gaps happen during interruptions.

Peeku brings an optional screen-saver-based walk-away lock, eye-rest nudges, Desk Health, and local presence coaching to the Mac App Store. Its lock setting needs no extra control permission.

What changes the score

Lock risk is mostly a timing problem.

A secure Mac needs two things to line up: the lock action must happen soon after you leave, and macOS must require a password as soon as that lock appears. A dark display without the password setting is not enough.

Peeku closes the timing gap by looking for local away evidence instead of waiting for idle time, with private walk and eye-rest reminders plus an optional screen-saver-based walk-away lock.

Password delay. The lock screen only protects the session if macOS asks for the password immediately.
Idle timeout. A ten-minute timer is fine while reading, but it leaves a ten-minute unattended gap.
Manual memory. Keyboard shortcuts work when you remember them. Interruptions are the hard case.
Presence signal. Local camera and optional Watch proximity let the lock decision follow whether you are there.

Pick the right build

Private coaching and optional walk-away lock, together.

Peeku Presence Coach is free on the Mac App Store for private walk reminders, eye-rest nudges, Desk Health, and local presence signals. If your score shows a real unattended-session gap, enable Peeku's optional screen-saver-based walk-away lock.
