What it does

You have a mouse with extra buttons. The vendor's companion app is 200 MB, wants an account, and breaks after every macOS update. You just want Back to send Cmd+[ in Safari, and Mission Control on the thumb button everywhere else. Ptions+ does that, from the menu bar, in about 8 MB of memory.

The profile editor. Each app gets its own set of button mappings.

Per-app profiles

Safari gets browser navigation, Xcode gets build shortcuts, everything else gets your defaults.

System actions

Mission Control, App Exposé, Show Desktop, and Launchpad, with a graceful fallback when macOS does not offer them.

18 preset actions

Next and Previous Space, Spotlight, Screenshot Tool, Notification Center, Lock Screen and more. Presets follow your active keyboard layout.

Shortcut recorder

Click Assign and press the combination — even system-reserved ones such as Control + Arrow that macOS would otherwise swallow.

Launch at login

Native SMAppService registration, with the system as the source of truth.

Debug monitor

A live view of raw mouse events, and which mouse produced them, so an unrecognised button is a two-minute diagnosis rather than a guess.

Multiple mice

Every connected mouse can carry its own model and mappings, remembered across reconnects.

Supported mice

Mouse model selection is manual. Any mouse that sends otherMouseDown events over HID works; pick the closest model, or one of the generic options.

Mouse models selectable in Ptions+
Logitech MX	Logitech G	Generic
MX Master 4	G502	Generic (5 buttons)
MX Master 3 / 3S / 2S	G604	Generic (3 buttons)
MX Anywhere 3
MX Ergo
MX Vertical

How to get it

Download the latest release. The DMG and ZIP are signed with a Developer ID certificate and notarised by Apple. Each release ships a .sha256 file so you can verify what you downloaded.
Remove vendor mouse software. Logi Options+ and similar tools capture the same buttons before Ptions+ can see them. Ptions+ cannot work alongside them.
Grant Accessibility permission. System Settings → Privacy & Security → Accessibility → enable Ptions+. Intercepting mouse events and posting keyboard events both require it; there is no way around this on macOS.
Optional: grant Input Monitoring. Only needed to tell several connected mice apart. Without it Ptions+ still lists your mice, but they all share one set of mappings.

Requirements

macOS 13 Ventura or later, on Apple silicon or Intel. Ptions+ runs in the menu bar and has no Dock icon.

Prefer to build it yourself, or want to read the code first? The build instructions and the full source are in the repository.

Privacy

Ptions+ collects nothing and sends nothing

The app makes no network requests. There is no telemetry, no analytics, no crash reporting, no update check, and no account. Your configuration is a single JSON file at ~/Library/Application Support/Ptions+/config.json, which stays on your Mac until you delete it.

This page behaves the same way. Every stylesheet, font, and image is served from this repository, so nothing here loads from a third party, sets a cookie, or records your visit.

Settings are fully operable from the keyboard and every control exposes a name to VoiceOver. Known limitations, including the parts that deliberately require a physical key press, are documented in the accessibility note.
