A twitching cursor mid-presentation
You're sharing your screen. The presentation's going well. And then — every minute, like clockwork — your cursor twitches. The whole meeting sees it. Some people pretend not to notice. Some people ask. It's not a great look.
Most mouse jigglers solve this by either turning off (so the Mac sleeps mid-call) or moving the cursor exactly one pixel (still visible at high DPI). Stealth mode does it right.
Zero-delta mouse events
Stealth mode posts a single mouseMoved CGEvent at the cursor's current position. No delta. The cursor doesn't move at all — but the macOS idle timer resets, presence systems register activity, and the Mac stays awake.
The event is real input as far as the OS is concerned. It just happens to be input that doesn't change anything visible.
Turn it on
- Open Settings (menu bar → Settings…).
- In the Shake section, turn on Invisible mode (no cursor movement).
The distance slider greys out — it doesn't apply in stealth. Click events (the toggle right below) are optional but recommended for screen-share scenarios.
Pair with click events
Some presence systems (Slack, Teams) only count a real click as "active." For those, the click events toggle is the missing piece: Shake It On fires a left-mouse-down/up pair after each shake.
With stealth mode + click events on, the click happens at the cursor's resting position. Park the cursor on something non-interactive (the desktop, a blank part of a window) before the click fires, so it doesn't accidentally trigger a button or link.
When stealth mode shines
- Live screen shares — Zoom, Teams, Meet, presentations.
- Screen recordings — Loom, OBS, ScreenFlow. Nothing twitches in the final video.
- Screenshots — set up a screenshot of a pristine UI without waiting for an awake Mac.
- Just for yourself — if a periodic cursor twitch in your peripheral vision distracts you.
Save it as a Session
If you screen-share regularly, save a "Presentation" Session:
- Invisible mode: on
- Click events: on (or off, depending on whether you need to defeat presence systems)
- Pause when camera in use: on (so it stops if you do hop on a video call)
- Pause when frontmost matches:
Keynote, Zoom(extra safety net)
One click from the menu bar to switch into Presentation mode, one click to switch back to your Default Session afterward.
vs. other stealth jigglers
Most "undetectable" or "1-pixel" mouse jigglers actually move the cursor by 1 pixel. At high DPI on a retina display, that's still visible if you're looking. Stealth mode in Shake It On posts a zero-delta event — there's literally no movement to see, on any display, at any zoom level.
