Mouse Halo
Find your pointer at a glance

Never lose
your pointer.

Mouse Halo draws a glowing ring around your mouse pointer and a small ripple where you click. Even on large or multiple displays, you can see where the pointer is right away.

The app and this website are in Japanese.

The settings panel is in Japanese. The download page and user guide are also in Japanese; the steps are short and described below.

Features

Features

A small app that lives in the menu bar. It has no Dock icon and no regular window.

A ring around your pointer

A glowing ring follows the pointer closely with no lag. Drawing is left to the GPU, so it uses almost no CPU while the pointer is still.

Click ripples

Left, right and other button clicks send out a short ripple from the click point (it fades in about half a second).

Stays out of the way

The ring is drawn on top of everything, but clicks and drags pass straight through to the app underneath.

Multiple displays

Works across displays, full-screen apps and all Spaces, and follows you when you plug in or remove a display.

Color, size and opacity

Pick any color, a ring size from 28 to 120 px and an opacity from 20 to 100%. Settings are kept between launches.

One switch in the menu bar

Click the menu bar icon to open the settings panel, turn the highlight on or off, and choose whether it opens at login.

Limits

What it doesn't do

  • Intel Macs and macOS 13 or earlier are not supported.
  • It doesn't change the pointer itself; it draws a ring over it.
  • It doesn't show keystrokes on screen.
  • There is no keyboard shortcut to turn it on or off.
How it works

Getting started

  1. Download and drag to Applications

    Open the DMG and drag “Mouse Halo” to “Applications”.

  2. Open the app

    A ring appears around your pointer right away. No window opens; a round icon appears in the menu bar.

  3. Adjust from the menu bar

    Click the icon to change the color, size and opacity, or switch the highlight off.

Privacy

Network and data

From 0.2.0, Mouse Halo's only network access is checking the official site (k386.sub.jp) for updates and downloading them. It doesn't send usage statistics or error reports. It handles only these four kinds of data.

Madoka

Pointer positions and clicks are only used for drawing, never saved.

  • It doesn't monitor the keyboard, read screen contents or record the screen (no Screen Recording permission).
  • macOS may ask for Input Monitoring so that ripples appear over other apps. The ring works without it.

FAQ

FAQ

Why is it free?

I built it for my own work and want other Mac users to be able to use it too. There are no ads and no paid upgrade.

Will it block clicks in other apps?

No. The ring doesn't receive mouse events, so clicks and drags go straight to the app underneath.

I don't see click ripples.

If Mouse Halo appears in System Settings → Privacy & Security → Input Monitoring, turn it on, then quit and reopen the app.

Does it work on Intel Macs?

No. It requires an Apple silicon Mac (M1 or later) and macOS 14 or later.

How do I update?

From 0.2.0, the menu bar icon changes to an arrow when a new version is out. Open it and click “今すぐ更新” (Update now): the app downloads the update, verifies its checksum, Developer ID signature and Apple notarization, replaces itself and restarts. On 0.1.0, download the new DMG from the download page and replace the app in Applications. Your settings are kept.

How do I uninstall it?

Choose “終了” (Quit) in the menu bar panel and move Mouse Halo from Applications to the Trash. If you like, also delete ~/Library/Preferences/dev.duca.MouseHalo.plist.
