Mouse Jiggler, a wakeup call for narcoleptic computers

A solution for Mac users who want to prevent their Mac going to Sleep while it's engaged in intensive tasks is available now in the UK, Mouse Jiggler.

AM Micro has begun shipping WiebeTech's USB dongle here. The device prevents a computer from entering sleep or screen saver mode by maintaining constant mouse activity. There's no software to install – it works with any computer with a spare USB port.

The solution seems set for particular use by those attempting to down- or upload large files, installing weighty software packages or running back-up processes, as it prevents the machine entering Sleep or ScreenSaver mode and interrupting the process.

Mouse Jiggler won't interrupt your normal workflow – the mouse movement it generates is near imperceptible, the company claims.

This device costs £22.95.
