If you’ve ever plugged a standard PC mouse into your MacBook and felt like your brain was melting, you aren’t alone. You scroll the wheel down, and the page goes up. You flip the "Natural Scrolling" setting in System Settings to fix it, and suddenly your trackpad feels broken because now that is inverted too. It is one of those tiny, baffling Apple design choices that makes you wonder if anyone at Cupertino actually uses a third-party mouse.
Basically, macOS links the scroll direction of your trackpad and your mouse together. Change one, and you change both. It's a "feature" that has stayed consistent all the way through macOS Sequoia and into the 2026 updates.
This is exactly why scroll reverser for mac exists. It’s a tiny, lightweight utility that does the one thing Apple refuses to do: it lets you set independent scroll directions for your mouse and your trackpad. Honestly, it’s usually the first thing I install on any new Mac setup.
Why Does macOS Force This on Us?
Apple’s logic is actually pretty simple, even if it’s annoying. They call it "Natural" scrolling because it mimics how you move a piece of paper on a table. If you push the paper up, the content moves up. On a trackpad, this feels great. It feels like you’re touching the content directly.
But a scroll wheel isn't a piece of paper. It’s a mechanical gear. For decades, "down" on a scroll wheel has meant "move the page down." When Apple introduced Natural Scrolling back in OS X Lion, they decided that the "physicality" of the gesture should be the same across all devices.
The problem? Most of us have muscle memory dating back to the 90s for how a mouse should work.
How Scroll Reverser for Mac Actually Works
The app is created by Nick Moore at Pilotmoon Software. It isn't some heavy suite of tools; it’s a menu bar app that sits there and intercepts "scroll events" before they reach the rest of the system.
When you move your scroll wheel, the app sees that event, checks which device it came from, and—if it’s the mouse—it flips the signal. Your Mac thinks you’re scrolling one way, but the app tells it you’re doing the opposite.
The Setup Process
Getting it running is sorta straightforward, but macOS security likes to throw a few hurdles in your way.
- Download and Unzip: You grab the app from the Pilotmoon website.
- Move to Applications: Don’t just run it from your Downloads folder. Drag it into
/Applicationsso it stays put. - The Permissions Dance: This is where people get stuck. Because the app needs to "watch" your mouse input, you have to go to System Settings > Privacy & Security > Accessibility and toggle it on. In 2026, you might also need to check the Input Monitoring section depending on your specific macOS version.
- Configuration: Once it's running in your menu bar, you just click the icon and hit Preferences.
The Secret "Step Size" Feature
Most people install scroll reverser for mac just for the direction flip, but there’s a hidden gem in the settings called "Step Size."
If you’re using a cheap Logitech or a gaming mouse, you might find that one "click" of the scroll wheel jumps the page way too far. Or maybe it’s too slow. Scroll Reverser lets you adjust the discrete scroll steps. It basically lets you turn off the system-wide scroll acceleration and use a fixed number of lines per tick.
It makes a $15 office mouse feel much more precise, especially when you're digging through long spreadsheets or lines of code.
Comparing Alternatives: Mos, LinearMouse, and Others
While Scroll Reverser is the classic choice, it isn't the only player in the game. Over the last few years, a few other apps have popped up that try to solve the same problem with slightly different flavors.

- Mos: This one is a fan favorite because it focuses heavily on "Smooth Scrolling." It makes a clunky mouse wheel feel almost as fluid as a trackpad. If you want your mouse to feel "Apple-like" but still scroll in the correct direction, Mos is a solid alternative.
- LinearMouse: This is the "power user" choice. It’s open-source and gives you an absurd amount of control over cursor acceleration and per-app settings. If you want your mouse to behave differently in Chrome than it does in Final Cut Pro, this is the one.
- Mac Mouse Fix: This app is more about gestures. It can turn your middle-click into a Mission Control trigger or a back button, while also handling the scroll reversal.
Common Issues and How to Fix Them
I've seen a few recurring complaints about scroll reverser for mac over the years. Usually, if the app stops working, it's because macOS "forgot" the permissions. This often happens after a major system update (like moving from Sequoia to whatever the 2026 release is).
If it stops reversing, don't just restart the app. Go into the Accessibility settings, remove Scroll Reverser from the list using the minus (-) button, and then add it back manually. Just toggling the switch off and on usually isn't enough to kick the system into gear.
Another thing: if you use "Zoom" gestures in Accessibility settings (the three-finger double-tap), it can sometimes conflict with how Scroll Reverser detects gestures. If your trackpad starts acting weird, try disabling that specific zoom feature.
Actionable Next Steps for a Better Mouse Experience
If you're ready to fix your Mac's scrolling for good, here is exactly how to set it up for the best experience:
- Keep macOS "Natural": In your System Settings, keep "Natural Scrolling" turned ON for both the trackpad and the mouse. This ensures that your trackpad gestures feel right and that things like "Swipe between pages" move in the direction you expect.
- Enable Scroll Reverser for the Mouse Only: Open Scroll Reverser's preferences. Under the "Scrolling Devices" tab, make sure "Reverse Mouse" is checked and "Reverse Trackpad" is unchecked.
- Set to Start at Login: Go to the "App" tab in preferences and check "Start at Login." You don't want to have to manually open this every time you reboot.
- Hide the Icon: If you're a minimalist, you can actually tell the app to hide its menu bar icon so it runs entirely in the background. You can always reopen the preferences by launching the app again from your Applications folder.
By following this specific configuration, you get the best of both worlds: a trackpad that acts like a modern touch device and a mouse that acts like a traditional tool. It removes that split-second of hesitation every time you switch from the keyboard to the mouse.
Fact Check & Compatibility Note
As of early 2026, scroll reverser for mac (specifically version 1.9 and above) is fully compatible with Apple Silicon (M1, M2, M3, and M4 chips). It requires macOS 13.5 or later. If you are running an older Intel Mac with an OS like Monterey or Big Sur, you should look for version 1.8.2 on the developer's site to ensure stability.
The app remains "Donationware," meaning it is free to use without a trial period or nag screens, but the developer, Nick Moore, accepts contributions via "Buy Me a Coffee" to keep the project alive.
