A small native menu‑bar app that remaps your mouse's buttons over HID++.
Free · MIT · No account · Apple silicon and Intel
No account, no background daemon and no kernel extension. Upright talks to the mouse directly. Built and verified on the Logitech MX Vertical.
Features
Upright lives in the menu bar, looks like part of macOS, and only does what you set up.
Buttons
Map Back, Forward, the top button, the wheel click and any other button your mouse lets software take over to Mission Control, a keyboard shortcut, an app, a URL or a Shortcuts.app shortcut.
Gestures
Set a button to Gestures and it gets a click plus hold-and-move up, down, left or right, while the mouse reports raw movement so the cursor stays where it is.
Per-app profiles
Keep one global setup and let apps override single buttons while they're in front, so in Safari the thumb buttons switch tabs and everywhere else they go back and forward.
Several mice · Battery alerts
USB cable, Bluetooth, Unifying, Bolt or Nano in any mix: each mouse gets its own row with its connection and battery, and a mouse that's asleep never holds up the others.
Low-battery alerts at 15% and 5%, for each mouse.
Pointer speed
Set the DPI with a slider, save presets and map a button to cycle through them; Upright applies your speed again whenever the mouse reconnects, rounded to what that mouse supports.
Mice with ADJUSTABLE_DPI (0x2201)
Wheel vs trackpad
Reverse the mouse wheel without touching the trackpad's Natural Scrolling, change the speed from 0.5× to 3×, or try the experimental smooth scrolling, all off until you turn it on.
Privacy
Upright talks to your mouse and nothing else. It doesn't phone home or collect anything.
Buttons are only diverted while Upright runs. Quit it, or switch the mouse off and on, and every button is back to factory behavior.
One native SwiftUI app in your menu bar. No kernel extension, no background service, no Logitech software and no account.
Upright only opens Logitech HID interfaces and only sends the actions you assign. Keyboards are never opened.
What Upright touches
Supported mice
The MX Vertical is tested on real hardware. Twenty-two more models are in the catalog, built from published device data and tested against Upright's mouse simulator, so they're expected to work but haven't been verified on hardware yet.
Connections: USB cable, Bluetooth, Unifying, Bolt and Nano receivers. G-series and PRO gaming mice keep their buttons in onboard profiles and aren't supported.
Install
Download the disk image from the latest GitHub release. It runs on macOS 13 Ventura or later, on Apple silicon and Intel.
The release build isn't notarized by Apple, so Gatekeeper blocks the first launch. Right-click Upright.app, choose Open, then Open again. You only need to do this once. If there's no Open button, use Open Anyway in System Settings → Privacy & Security, or run:
xattr -dr com.apple.quarantine /Applications/Upright.appYou need Xcode 15.3 or later, and no Apple Developer account.
git clone https://github.com/dpdev69/upright.git
cd upright
make app
open build/Build/Products/Release/Upright.appQuit Logi Options+ and take it out of your login items first. It, Solaar and LogiOps divert the same buttons, and only one app can have them.

Yes. It's open source under the MIT license, with no account and no subscription.
The MX Vertical is verified on real hardware. Other Logitech mice that speak HID++ 2.0 and have programmable buttons are expected to work, including the MX Master, MX Anywhere, MX Ergo and Lift families, but they haven't been verified on hardware yet. Upright decides by what a mouse answers, not by its name, so mice outside the catalog can work too.
A build that isn't notarized is blocked by Gatekeeper on first launch. Right-click Upright.app, choose Open, then Open again. You only need to do this once.
Quit it and take it out of your login items while you use Upright. Logi Options+, Solaar and LogiOps divert the same buttons, and only one app can have them.
No. Nothing is written to the mouse's memory. Quit Upright and your buttons go back to normal straight away.
Accessibility, to send the shortcuts, clicks and media keys your buttons are mapped to. Input Monitoring only if macOS hides a mouse over Bluetooth. Mission Control actions, opening apps and pointer speed work without either.
Yes. Open Upright.xcodeproj in Xcode 15.3 or later and press ⌘R. You don't need an Apple Developer account.
Turn off Open at login in Settings → General if you turned it on, quit Upright and delete Upright.app. Nothing was written to the mouse, so there's nothing to undo there. The install guide also shows how to remove its settings.
Free, open source, and about a minute from download to your first remapped button.
