MacShield for macOS

Ready for the unexpected.

MacShield trigger settings

01 / Detect

A move. An unplug. A response.

Movement detection watches for suspicious MacBook movement while armed. Choose your supported triggers and sensitivity in the actual MacShield controls.

Unplug detection

When armed while charging, disconnecting power can trigger protection. Lid closure can be monitored too.

02 / Deter

Harder to ignore.

A supported triggering event starts an audible alarm and full-screen deterrent, helping draw attention to your Mac. MacShield is a deterrent, not a physical lock.
