Cursr

Cursr is a macOS utility that gives you precise, configurable control over how your cursor moves across the boundary between two or more displays.

What is Cursr?

Cursr is a lightweight Mac app designed to solve one of the most underappreciated frustrations in multi-monitor life: the cursor behaving unpredictably or awkwardly when you slide it from one screen to another. Instead of accepting whatever macOS decides about where your pointer enters and exits each display, Cursr lets you define that behaviour on your own terms.

If you have ever spent a fraction of a second hunting for your cursor after it slipped to a monitor you weren't expecting — or felt the jolt of your pointer snapping past a display edge at the wrong height — Cursr is the fix you didn't know had a name.

What does Cursr do best?

Cursr excels at remapping the physical crossing points between your displays so that cursor transitions feel intentional rather than accidental.

Out of the box, macOS determines how screens relate to each other based purely on the arrangement you draw in System Settings → Displays. That arrangement is a blunt instrument: if your secondary monitor sits slightly lower than your primary, the crossing zone shifts, and your muscle memory has to compensate every single time. Cursr lets you define custom transition zones — think of them as virtual gates in the bezel — so you can lock the cursor to a specific entry point, slow it down as it crosses, or require a deliberate flick rather than an accidental drift.

I run a 27-inch display beside a 14-inch MacBook Pro lid and the height mismatch used to cost me a half-second of confusion on every cross-screen drag. After an afternoon with Cursr, that friction is gone. The cursor now crosses where I expect it to, every time.

Who should use Cursr?

Anyone running two or more displays with mismatched sizes, resolutions, or physical heights will notice an immediate quality-of-life improvement.

Cursr is particularly valuable for:

• Developers who keep a code editor on one screen and a browser or terminal on another, and drag text or windows between them constantly.
• Video editors and designers where a stray cursor crossing mid-drag can mean a ruined clip placement or a misaligned object.
• Writers and researchers who reference material on a secondary display while typing on a primary — accidental crossings break flow.
• Anyone with a MacBook docked to an external monitor where the screen-size disparity makes macOS's default crossing point feel geometrically wrong.

If you use a single display, Cursr offers nothing. But the moment you add a second screen, it earns its keep.

How much does Cursr cost?

Cursr is free to download from its official site and is also available via Homebrew Cask, making installation a one-liner for terminal-comfortable users.

The developer has kept the app free, which puts it in a different category from commercial multi-display tools like Moom or Magnet — those focus on window snapping rather than cursor routing, but they carry price tags. Cursr solves its narrower problem at no cost, which makes it an easy add to any Mac setup.

What are the best Cursr alternatives?

Cursr's closest functional neighbour is Barrier (or its successor Input Leap), though that targets a different problem — sharing one keyboard and mouse across multiple physical computers. For display-specific cursor behaviour on a single Mac, Macs Fan Control, Display Menu, and system-level tweaks in BetterTouchTool can approximate some of what Cursr does, but none match its specificity.

BetterTouchTool is worth mentioning directly: it is a Swiss-army knife that can constrain cursor movement and set up display-edge actions, but configuring it for cursor transition control requires significant setup time. Cursr is purpose-built and therefore immediately understandable — you open it, see your display arrangement, and start adjusting crossing zones in minutes rather than hours.

For pure window management across displays, Moom, Mosaic, and Rectangle are excellent — but they do not touch cursor routing.

How does Cursr compare to BetterTouchTool?

BetterTouchTool can do what Cursr does, but Cursr does only that one thing — and does it with far less configuration overhead.

BetterTouchTool costs a licence fee and covers input remapping, gesture control, Touch Bar customisation, window snapping, and cursor behaviour all at once. If you already own it, you may not need Cursr. But if you want a zero-friction, free, single-purpose fix for multi-display cursor crossing, Cursr is the cleaner answer. I keep both installed: BetterTouchTool for gestures, Cursr for display transitions.
