Jiggler

What is Jiggler?

Jiggler is a macOS utility for preventing sleep and screensavers during long-running tasks. It is designed for people who want their Mac to stay awake while downloads, processing jobs, music playback, disc burning, or specific apps are active. Jiggler works by occasionally moving the mouse pointer, and it can be configured to do that only after your Mac has been idle for a while so it stays out of the way during normal use. It also offers condition-based behavior, including keeping the Mac awake when the computer is busy, when music is playing, or when a chosen application is running. Jiggler is published by Ben Haller as a Stick Software product and is offered as freeware for Mac users who need a simple sleep-prevention helper.

Key features

• Keep your Mac awake by periodically moving the mouse pointer
• Run only after the computer has been idle for a set period
• Prevent sleep during long tasks when the Mac is busy working
• Stay active while music is playing so playback is not interrupted
• Keep the Mac awake when a specific application is running
• Help prevent sleep during disc-burning sessions

Safety overview

Status: Mostly safe

Jiggler is a legitimate utility whose purpose is to simulate small pointer movement to keep a Mac awake. Because it controls mouse movement, users may be asked to allow Accessibility access, which is normal for this kind of tool. That permission lets the app control input-related behavior, so it is best to install it from a trusted source and grant access only if you want its stay-awake feature.

Recommendation: Keep Jiggler if you intentionally use it to stop your Mac from sleeping during long tasks or playback. If you no longer need that function, you can remove it without affecting macOS beyond losing its keep-awake behavior.
