Can a Mac App Store app automatically lock my Mac?

Yes. Peeku on the Mac App Store can trigger macOS’s standard Lock Screen shortcut when its on-device checks show you have stepped away, after you explicitly grant Accessibility permission. It also provides 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.

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's full Mac app closes the timing gap by looking for local away evidence instead of waiting for idle time. Peeku Presence Coach is the safer App Store path for people who want private walk and eye-rest reminders first.

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.
