Learn how MacUpdate Desktop makes installing apps from MacUpdate.com one-click easy.
Next time, install RedHand with 1-click

Learn how MacUpdate Desktop can install apps on MacUpdate with the simple click of the Install apps with MacUpdate Desktop icon. Plus, keep all your apps updated.

RedHand locks your computer. Manually via global hot key, menu bar or dock. Automatically after a period of inactivity (much like a screensaver), depending on the presence of a Bluetooth device, or whenever your computer goes to sleep.

Whenever someone tries to gain access to your computer, RedHand takes a photo and informs you about it.

You don't have to think about locking your computer. You don't even have to remember your password. Use your phone as the key! Just tell RedHand to look for a specific Bluetooth device. If you leave the room your computer will be locked. As soon as you are back you'll find it
