MockTab

Native Mac driver for Wacom drawing tablets that no longer have official support on macOS.

---

Wacom hardware tends to outlast its driver support. MockTab aims to be a small, focused driver for Wacom tablets from the early 2000s through the early 2020s, on macOS Ventura and later.

---

Supported hardware

Several Wacom models across multiple protocol families:

• Intuos 1–5 / Intuos Pro Gen 1 (PTH-x50/x51, PTZ, PTK series) — USB
• Intuos Pro Gen 2 (PTH-460, PTH-660, PTH-860) — USB and Bluetooth Classic
• Intuos Pro Gen 3 (PTK-470, PTK-670, PTK-870) — USB, experimental
• Cintiq pen displays (CintiqV1 and IntuosV2-format models)
• DTU / DTUS small pen displays — USB, experimental
• Bamboo and consumer CTL/CTH tablets

Full list: mocktab.org/hardware

MockTab covers a small set of hardware so far and may not work with your configuration. Filing an issue with a diagnostic detail can help improve support.

Requirements

macOS 13 (Ventura) or later.

Install

1. Download the latest .dmg from Releases.
2. Drag MockTab.app to Applications and launch it.
3. Grant Accessibility when prompted — click "Open System Settings", toggle MockTab on, relaunch. MockTab needs this to provide pen pressure.
4. Grant Input Monitoring if prompted.
5. Plug in or pair your tablet. It appears in the menu bar.

If permissions don't seem to take effect: remove MockTab from the pane and re-add it. Moving or reinstalling the app may invalidate previous approvals.

Features

• Tablet area mapping — choose which part of the surface maps to the screen; proportional lock keeps circles round at any aspect ratio
• Pressure curve — two-point Bézier editor with Linear, Soft, and Firm presets; tested with Photoshop, Affinity, Krita, and Clip Studio
• Button mapping — remap barrel buttons, express keys, and touch ring to any modifier + key combination; live key capture
• Per-app overrides — different area, pressure curve, buttons, and display routing per app; switches automatically when the app comes forward
• Touch ring — multi-slot modes with per-slot clockwise/counter-clockwise actions; cycle slots with a button assignment
• Display mapping — route the tablet to any connected display; Display Toggle action cycles displays from a button
• Live scratchpad — test pressure, tilt, and button assignments before opening your real work
• Profile import/export — drag a profile card to Finder to export as JSON; drag a file back in to import
• Multiple tablets — connect several tablets simultaneously; switches automatically based on which one you pick up
• Wireless — USB dongle and Bluetooth where hardware supports it
• Capacitive touch — two-finger scroll, tap-to-click, and adjustable touch area on models with a touch surface
• Undo everywhere — ⌘Z across every settings pane
• Menu bar mode — hides the Dock icon
• Native AppKit app, signed and notarized, without kernel extensions

TabletKit (Swift package)

MockTab's HID report decoders — the pure-logic layer that turns raw tablet reports into pen / aux / touch events — live in a sibling repository, mocktab-kit, and are consumed here as a SwiftPM dependency named TabletKit. Anything in MockTab/Driver/ that's still here is the app-specific glue (IOKit transport, event injection, device routing) that depends on TabletKit but isn't part of it.

// Package.swift of a consumer project
dependencies: [
    .package(url: "https://github.com/Cyzor/TabletKit", from: "0.1.0"),
],
targets: [
    .target(name: "MyApp", dependencies: [
        .product(name: "TabletKit", package: "TabletKit"),
    ]),
],

import TabletKit

var state = DecoderState()
var decoder: any TabletReportDecoder = IntuosV2Decoder()
let results = decoder.decode(report: ptr, length: len, spec: spec, state: &state, deviceFamily: "intuosProGen2")

Scope. TabletKit is pure Swift — no AppKit, no event injection. It decodes; you bring the HID transport and the event sink.

Stability. The public API surface (see mocktab-kit/CHANGELOG.md) is at 0.1 — workable but pre-1.0. Expect breaking changes until the first vendor outside Wacom (Xencelabs likely first) lands and the protocol shape is validated against more than one family.

Tests. TabletKit's 259-test suite runs from its own repo (cd ../mocktab-kit && swift test).
