TPCurveFull control of your trackpad and mouse curves.
macOS gives you a single speed slider. TPCurve gives you the rest: turn acceleration on or off, stop scrolling from speeding up, set your mouse and trackpad separately, or match the feel of Windows.
14 days free, no account needed. macOS 14 or later, Apple Silicon and Intel.
What macOS won't let you change.
If you've ever thought "why can't I just turn that off?", you're not alone.
| On a Mac | With TPCurve |
|---|---|
| One natural-scrolling setting for both mouse and trackpad. | Each device scrolls the way you want. |
| The mouse wheel scrolls further the faster you spin it. | Turn scroll acceleration off: every click moves the same amount. |
| Trackpad acceleration is always on. | Turn it off for a steady, predictable pointer. |
| You can't change how the pointer speeds up. | Pick a feel, or shape the curve yourself. |
| One speed slider with a few steps. | Fine control, separately for mouse and trackpad. |
Everything in one small menu.
Changes apply instantly, and stay on in the background.
Mouse and trackpad, separately
Each has its own speed, feel and scroll direction. Use both at once and each one just works.
Acceleration on or off
Keep the pointer at one steady speed, or let it speed up as you move faster. Your choice, for each device.
Better scrolling
Turn off scroll acceleration so each wheel click moves the same distance, and set how far each scroll goes.
The Windows feel
Curves recorded on real Windows laptops and mice. Pick the Windows speed number you used to use.
Your own curve
Set speed, acceleration, shape, where it starts and how far it goes. Watch it on a live graph and save up to three.
Made for your mouse
Enter your mouse's DPI and the pointer follows your hand, whichever mouse you use.
Coming from Windows?
Pick the same speed number you had there: 1–10 for trackpads, 1–20 for mice.
Your hand remembers how Windows moves the pointer, and the Mac does it differently, so clicks land short or overshoot. TPCurve's Windows curves were recorded on real Windows hardware and matched to how far your hand actually moves, so they feel the same on any Mac screen.
Set up in a minute.
TPCurve walks you through it the first time it opens.
Install
Open the download and drag TPCurve into Applications.
Allow access
macOS asks you to allow TPCurve to adjust the pointer, and to switch off Shake to locate. The setup guide shows you exactly where to click.
Pick your feel
Choose Mac, Windows or Custom for your mouse and trackpad from the menu bar. It keeps working, even after restarts.
One price. Yours to keep.

Questions
Anything else? support@tpcurve.app
- Do I need to have used Windows?
- No. Many people use TPCurve just to turn off acceleration, fix scrolling, or give their mouse and trackpad different settings. The Windows curves are one option among several.
- Does it work with my mouse or Magic Trackpad?
- Yes: the built-in trackpad, Magic Trackpad, and any USB, Bluetooth or wireless mouse. The mouse and the trackpad each keep their own settings.
- Why does TPCurve need Accessibility and Input Monitoring?
- Accessibility lets TPCurve adjust how far the pointer moves. Input Monitoring lets it read your mouse's exact movement, for accurate mouse settings. TPCurve only works with pointer movement and scrolling. It never reads what you type, and never sends anything about how you use your Mac.
- Will it slow my Mac down or drain the battery?
- No. Each movement takes a few millionths of a second to adjust, so there's no lag, and TPCurve does nothing while the pointer is still. In our tests it used roughly 0.1–0.3% battery an hour of normal use.
- Why does the pointer sometimes grow big?
- That's a macOS feature called Shake to locate: it enlarges the pointer when it moves back and forth quickly, and TPCurve's curves can set it off. TPCurve's setup guide asks you to switch it off: open System Settings, then Accessibility, Display, and under Pointer switch off Shake mouse pointer to locate.
- What happens when the trial ends?
- Your mouse and trackpad go back to how macOS normally works until you enter a licence key. Nothing breaks, and your settings are kept.
- Can I use one licence on several Macs?
- Yes, on up to 3 Macs. To move it to another Mac, open TPCurve's Licence window and choose Deactivate This Mac.
- How do I go back to normal, or uninstall?
- Choose Mac for a device, or press ⌃⌥⌘M, to use macOS's own settings. To remove TPCurve completely, choose Uninstall… in its menu. It removes everything it added.
- Can I get a refund?
- Yes. If TPCurve isn't right for you, email us within 14 days of buying for a full refund.
