Which one is for you
Pick Mac Mouse Fix if
- Fits if you have a mouse with 5 or more buttons and want trackpad gestures on it
- Works for people whose wheel scrolling on a Mac feels jerky
Look elsewhere if
- Skip it if you use an Apple Magic Mouse, which isn't supported
- Not for you if your mouse has fewer than 5 buttons, since the trackpad gestures need them
- Watch out: on some mice built for drivers like Logitech Options, it can't recognize every button
- Not for you if you need a standard open-source license, as the source is under the developer's own MMF License
- Skip it if you're on Windows or Linux; Macs on macOS 10.13 to 10.15 are left on the older Mac Mouse Fix 2
Pick Mos if
- Fits if you use a wheel mouse on a Mac and want it to scroll like a trackpad
- Works for per-app scroll settings
Look elsewhere if
- Not for you if you use Windows or Linux, as it is Mac only
- Watch out: the CC BY-NC 4.0 licence is non-commercial, not a standard open source one
- Too light for you if you want paid support: its own comparison page points those users to commercial tools
- Watch out: it needs the macOS Accessibility permission

|---|---|---|
| Value for money | A$2.99 once, plus local taxes, no subscription. Utilities here sit at $2.99 a month in the middle, so this is one month's money for keeps, and the licence syncs to your other Macs through iCloud. | AFree to use, with a donate link offered, and no paid plan is listed on the site. |
| Free plan and trial | CNo free plan for version 3. You get 30 free days with no card asked for, and a day only counts when you actually use the app. Macs on macOS 10.13 to 10.15 need Mac Mouse Fix 2, which the developer says stays free. | AThe whole app is free, with no paid edition, limit or trial on record. |
| Features | CGiving a third-party mouse trackpad manners is its one job, and it covers it: side-button drags for Mission Control, desktops and App Exposé, drag-to-scroll with inertia, three smoothness settings, any button on any shortcut. On some mice built for Logitech Options it can't see every button. | BSmooth scrolling, per-app profiles, separate axes, button bindings and Logitech support. Nothing in the listing is missing from the job, though pointer acceleration is left to other tools. |
| Ease of use | BNo store rating on record, but there's nothing to set up: install it, pick what each button does and how smooth the scrolling should be. The mouse's scroll direction is set separately from the trackpad's. | BA menu bar app that works once the Accessibility permission is granted. No store rating is on record. |
| Platforms and integrations | DMac only. The latest version is made for macOS 11 Big Sur or later. No integrations are listed, and there's nothing for Windows or Linux. | CMac only. No Windows, Linux or phone version. |

Worth knowing
Mac Mouse Fix
- macOS only. The latest version is made for macOS 11 Big Sur or later; macOS 10.13 to 10.15 need Mac Mouse Fix 2, which the developer says stays free.
- The trackpad gestures as described need a mouse with at least 5 buttons, and the Apple Magic Mouse is not supported.
- On some mice built for proprietary drivers such as Logitech Options, the app cannot recognize every button.
- The source is under the developer's own MMF License, which restricts publishing compiled copies; it is not a standard open-source license.
Mos
- Mac only; it needs the macOS Accessibility permission to work.
- Licensed under CC BY-NC 4.0, which is a non-commercial license rather than a standard open source one.
- Its own comparison page says users who want paid support or a commercial product lifecycle may prefer commercial tools.
- Pointer acceleration and broader device settings are better handled by other tools, according to the vendor.
Key features
Mac Mouse Fix
- Trackpad gestures from a side button
- Hold button 4 and drag up for Mission Control, sideways to move between desktops or down for App Exposé. A single click triggers Look up and Quick Look.
- Click and scroll
- Holding a button while turning the wheel shows the desktop, opens Launchpad or zooms in and out in apps such as Safari and Preview.
- Scroll and navigate by dragging
- Hold button 5 and drag to scroll in any direction with inertia, or drag sideways to go back and forward, as a two-finger swipe does on a trackpad.
- Smooth scrolling
- Three smoothness settings: High adds trackpad-like momentum and a bounce at the end of a page, Regular uses short animations, and Off scrolls a set number of lines per step.
- Scroll direction and modifiers
- The mouse's scroll direction is set independently of the trackpad or Magic Mouse, and holding a keyboard modifier while scrolling gives precise scrolling or zoom.
- Button actions and shortcuts
- Assign an action to a click, double click or click and drag of any button, including any keyboard shortcut, such as copy and paste or volume control.
Mos
- Smooth wheel scrolling
- Turns raw wheel steps into continuous motion, with step, speed and duration values that can be tuned.
- Per-app profiles
- Each app can inherit the defaults or override its own scroll and button behavior.
- Separate axes and reversal
- Vertical and horizontal scrolling are configured independently, and direction can be reversed per axis.
- Mouse button bindings
- Record a mouse, keyboard or custom event and bind it to an action such as Mission Control, Spaces, screenshots or a script.
- Logitech button support
- Handles button events from Logitech devices connected over Bolt, Unifying or Bluetooth.
- Scroll hotkeys
- Keys can be bound to accelerate scrolling, convert the axis or temporarily turn smoothing off.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
