Made for MacBook

Your Mac stays alert.

A focused physical-security alarm for the moments you step away. MacGuard reacts locally and can send alerts to your paired iPhone or iPad.

Built for the moments when you step away.

Choose the protections that fit the situation. MacGuard can watch a MacBook on an open desk or guard the next open and wake while it is closed.

01

Desk protection

Monitor movement, keyboard or pointer activity, lid state, and wake events while your MacBook is open.

02

Closed / Sleep Guard

After a short grace period, the next lid open or wake triggers protection.

03

Immediate local alarm

The default-on siren starts on the Mac even if the internet or cloud service is unavailable. A clearly indicated silent mode is available for testing.

Local protection, with a secure line to your companion.

01

Arm the Mac

Choose Desk protection or Closed / Sleep Guard and enable only the triggers you want.

02

Step away

MacGuard watches locally. The Mac alarm does not depend on Firebase or an internet connection.

03

Get the alert

If cloud alerts are enabled, MacGuard can send the reported event toward the paired iPhone or iPad, which can securely request private photo evidence. A sent status does not prove the notification was displayed.

Designed around the moment that matters.

The companion view shows the current interface with clearly staged example alert data. Supporting artwork illustrates the Mac and evidence flow.

Useful evidence, with deliberate limits.

When an alarm is active, MacGuard can record a camera-only incident movie for up to about 20 seconds. When successfully recorded, incident video is saved only in MacGuard’s local Application Support folder and is never uploaded. Local retention and deletion settings may later remove it.

  • Face presence is detected locally—not identity
  • Up to three compressed JPEG photos per incident
  • Photos are available only to the currently paired companion
  • No public links and no evidence-sharing feature

Scan. Compare. Approve.

MacGuard does not require an account. A one-time QR code or 10-digit pairing code starts the connection, both devices show the same six-digit verification number, and the Mac owner must approve the match.

MacGuard checks the hardware it can actually use.

Apple silicon MacBook models can expose different motion and lid sensor channels. After helper authorization, the Mac app shows whether movement, gyroscope, lid-angle, and input protection are available on that Mac. Unsupported sensor protections are turned off while other available protections remain usable.

No accounts. No ads. No tracking.

MacGuard collects only what its security features need. It does not record typed text, collect location, use advertising SDKs, or track you across other companies’ apps and websites.
