Mouse jiggler for Mac: what actually works

Most "mouse jiggler mac" results are an App Store listing, a two-year-old Reddit thread, and a handful of small niche sites that all say roughly the same three sentences. Here's the actual comparison: the free command already built into macOS, the real App Store apps, and why the classic free Windows jigglers never got a Mac port.

The free, no-install option: caffeinate in Terminal

Every Mac ships with caffeinate, a built-in command that issues a power-management assertion telling macOS not to sleep, dim the display, or spin down the disk. Open Terminal and run:

caffeinate -d

…and your Mac stays awake until you close the window or press Ctrl+C. It's genuinely useful for long downloads, screen shares, or presentations where you just need the machine itself to stay on.

What it doesn't do is simulate a mouse move or keypress. caffeinate is a power assertion, not synthetic input, and Slack's away timer watches for actual input, not whether your Mac is allowed to sleep. So a common assumption trips people up here: keeping your Mac awake with caffeinate does not, by itself, keep your Slack status green. If Slack is your actual goal, see our dedicated breakdown of why caffeinate and Caffeine-style apps don't keep Slack active for the full explanation and what to run instead.

Mac App Store jiggler apps, compared

Unlike caffeinate, these actually inject synthetic cursor movement, the way a Windows jiggler does:

All three do the same core thing: nudge the cursor on an interval to reset your Mac's own idle timer and, incidentally, Slack's input-based one too. Like any locally-running program, they'll appear as a live process in Activity Monitor, and none of them survive your Mac going to sleep.

Why most free Windows jigglers don't have a Mac build

Mouse Jiggler (the open-source classic), Move Mouse, and JiggleMouse are all Windows-only, and it's not an oversight. All three are built directly against the Win32 API (SendInput and related calls) to simulate input at the OS level, which has no macOS equivalent. Porting one means rewriting the input-simulation layer with Apple's own APIs (CGEventCreateMouseEvent) from scratch rather than recompiling, which is most of why the handful of Mac-native apps above are separate projects with different developers rather than official ports.

Browser-based: Move My Cursor also works on Mac

If you'd rather not install anything at all, Move My Cursor runs entirely in a browser tab and works identically on macOS, Windows, or Chromebook. It's the fastest option for a one-off session, though the open tab itself is just as visible to anyone checking your browser history as an installed app would be. See our full mouse jiggler software roundup for how it stacks up against every option here on cost, platform, and detection risk.

Can your employer detect a mouse jiggler on Mac?

Potentially, yes, the same as on Windows. Anything that installs and runs locally, whether it's an App Store app or a Terminal session, shows up as a live process in Activity Monitor, and it's not hidden from basic inspection. The bigger 2026 risk is behavioural: monitoring tools are increasingly trained to flag the metronomic pattern a jiggler produces, since a script repeats the same nudge on the same interval while a real hand drifts and pauses. A cloud presence service is structurally different: it never touches your Mac, so there's no process and no local movement pattern for monitoring software to inspect in the first place.

If it's actually a coworker you're wondering about

Everything above assumes you're trying to manage your own status. If instead you're staring at a colleague's green dot that never seems to move and wondering what's behind it, that's a different question with a different answer, see why a coworker might always be green on Slack (but never responds).

FAQ

Is there a mouse jiggler app for macOS?
Yes. The Mac App Store has several, including Mouse Jiggler – Mouse Mover, Auto Mouse Jiggler Mover, and Jiggler (built on the open-source bhaller/Jiggler project). None of the classic free Windows jigglers have a Mac build.

Can my employer detect a mouse jiggler on Mac?
Potentially, yes. A locally-running jiggler shows up as a process in Activity Monitor, and monitoring software can flag the unnaturally regular cursor movement it produces. A cloud presence service has no local process for monitoring software to inspect.

Can you tell if someone is using a mouse jiggler?
Sometimes. A jiggler leaves a process name in Activity Monitor or Task Manager and a movement pattern that's too regular to be a real hand. Neither Slack nor Teams flags jigglers directly, IT-side monitoring tools are what pick up on it.

Is there a mouse jiggler that cannot be detected?
Not one that runs on your own machine. The closest thing is a cloud presence service, which doesn't run a jiggler at all, there's no process on your laptop and no cursor pattern to analyse.
