Transform and own
your MX Master 4.
Click a button on the mouse, choose what it does, and make a different profile for any app that needs one.
Built around your mouse
Click, map, go.
Click a control on the mouse, find its action, and save. Facet applies the change immediately and switches profiles with the app you are using.
Haptic Sense Panel
Tap it. Hold it.
Flick it
Give a tap its own action, or hold the Haptic Sense Panel to open the Action Ring. Move toward a petal and release to run it. Every gesture can become a command that feels natural to reach.
Move around the ring to preview each action
Own your Spaces
Take the window with you.
Point at a window's title bar and hold the Haptic Sense Panel. Facet confirms when it is locked. Move the window naturally, or use the configured left and right chords to carry it across Spaces.
Reviews.
Feedback shared during development.
“Logi Options+ hadn’t worked for months, so I had stopped using the haptic panel and extra buttons. Facet unlocked the whole mouse—and made my Mac much better to use.”
Five-day free trial

No card and no stripped-down trial. After five full days, keep Facet with one lifetime purchase for up to three personal Macs.
Good to know
Common questions.
Why are Accessibility and Input Monitoring both needed?
Input Monitoring lets Facet see mouse events. Accessibility lets it send the keyboard shortcuts and remapped clicks you choose.
What if back and forward are still inconsistent?
Try native Mouse Button 4/5 actions first. For browsers that ignore them, choose Browser Back or Browser Forward instead. Also fully quit Logi Options+ so two tools are not remapping the same button.
Can the Haptic Sense Panel modify the middle button?
Yes. Tap, double tap, and hold + left, middle, or right click are separate mappings. Normal clicks remain unchanged when the panel is not held.
Can Facet move a window between macOS Spaces?
Yes. Point at the title bar, hold the Haptic Sense Panel until the lock confirmation, then use the configured previous/next Space chords. You can also reposition the locked window before releasing the panel.
Does Facet work on Windows?
No. The current Facet release is built only for macOS and Apple silicon. A Windows version would require a separate port and is not available today.
Does this work on Intel Macs or other Logitech mice?
This build is for Apple silicon and is tested primarily with MX Master 4. Other Logitech mice may work, but they are not officially supported yet.
Is this an official Logitech app?
No. Facet is an independent Mac app and is not affiliated with or endorsed by Logitech.
