Troubleshooting

Common problems when a Wacom tablet stops working after a macOS update, and what to do about them.

Symptoms

These situations may indicate that macOS is no longer compatible with your Wacom driver.

Affected hardware

Wacom removes older models from its supported device list with each major driver release. Families that Wacom has dropped on macOS 14 (Sonoma), 15 (Sequoia), and 26 (Tahoe) include:

Intuos Pro Gen 2 (PTH-460, PTH-660, PTH-860) and Gen 3 (PTK-470, PTK-670, PTK-870) retain official support at the time of writing. Wacom's driver release notes, accessible via the Wacom driver download page , are the authoritative source for current compatibility; check the "compatible products" link inside each release's notes before installing.

Staying on Wacom's driver

If your model still appears in Wacom's supported device list, rolling back to an older driver version sometimes restores connectivity. Wacom publishes previous releases on its support site, with notes about which hardware each version covers. Back up your current pen and ExpressKey settings in Wacom Center before uninstalling, as the process erases your configuration.

Important — Wacom's official guidance
Run a clean uninstall before installing an older or newer driver version. Use the Wacom Tablet Utility (included inside the driver package) rather than simply deleting the application folder. Most driver files live outside /Applications; a manual drag-to-trash misses them. Wacom also provides a standalone Wacom File Utility for a more complete removal. Restart after uninstalling.
macOS Ventura 13 and later — Background access
On macOS 13 (Ventura) and later, you must explicitly allow the Wacom driver to run in the background. After installation go to System Settings → General → Login Items → Allow in the Background and toggle Wacom to ON, then reboot. Skipping this step produces the "tablet driver is not responding" error even when all other permissions look correct.
Missed the permission prompts?
Permission prompts fire the first time the driver exercises each protected capability. If they never appeared, uninstall and reinstall the driver to trigger them again.

If Wacom removed your model from the supported list entirely, no version of the current driver will recognize it. MockTab addresses this case directly, as do the outside tools described below.

macOS permission setup

macOS security settings frequently block a correctly installed driver. Grant the Wacom driver permissions in System Settings → Privacy & Security:

Permission What to enable What breaks without it
Accessibility com.wacom.IOManager Pen input events cannot be posted; security error appears
Input Monitoring WacomTabletDriver, WacomTouchDriver Tablet not detected; cursor doesn't move
Login Items → Allow in Background Wacom (toggle on) "Tablet driver is not responding" on Ventura 13+

Resetting stuck permissions

After a major macOS upgrade, the OS can lose track of previously granted permissions even though the toggle appears enabled. The fix is to remove and add each entry again:

  1. Disconnect the tablet.
  2. Open System Settings → Privacy & Security → Accessibility. Select com.wacom.IOManager and click to remove it.
  3. Repeat in Input Monitoring for WacomTabletDriver and WacomTouchDriver.
  4. Restart the Mac.
  5. After rebooting, manually add the entries back using the + button. The driver files live at:
    • /Library/PrivilegedHelperTools/com.wacom.IOManager.app → Accessibility
    • /Applications/Wacom Tablet/.Tablet/WacomTabletDriver → Input Monitoring
    • /Applications/Wacom Tablet/.Tablet/WacomTouchDriver → Input Monitoring

    Press Command+Shift+. in Finder to reveal hidden folders like .Tablet.

  6. Reconnect the tablet and test.

System maintenance tools

System-cleaning utilities can silently delete Wacom background services and preference files. If the driver stops working after running one of these tools, do a full clean uninstall with the Wacom Tablet Utility and reinstall fresh. Wacom publishes a dedicated guide for CleanMyMac interference on its support site.

Switching to MockTab

MockTab communicates directly with the macOS Human Interface Device (HID) subsystem and does not depend on Wacom Center, com.wacom.IOManager, or any background services. The Hardware page lists every device MockTab recognizes and its confirmation status.

1. Check hardware compatibility

Confirm your model appears on the Hardware page. Confirmed entries reflect models the project has tested on real hardware. Entries based on protocol references have reasonable confidence, but some details (express key counts, touch behavior, LED ring) may need further validation. File an issue with observations if something doesn't match.

2. Remove Wacom's driver

Running two tablet drivers simultaneously causes input conflicts. Both try to claim the same HID device, which produces erratic behavior. MockTab will show a conflict warning when it detects a competing driver. Use Wacom's uninstall utility or the standalone Wacom File Utility for a complete removal; simply deleting the app leaves service files behind. Restart after removal.

If full removal isn't practical, utilities such as App Tamer or LaunchControl can suspend the Wacom background process without uninstalling the driver.

3. Install MockTab

Download the latest disk image from Releases, open it, and drag MockTab to Applications. Launch it from there; macOS requires the app to run from its final location before granting permissions.

4. Grant permissions

MockTab requires Accessibility and Input Monitoring grants. The Configuration page walks through both prompts with screenshots. If a toggle doesn't take effect, remove MockTab from the privacy pane and it again; macOS binds grants to the app's path, so a previous grant from a different location doesn't carry over.

Common post-install issues

Pen moves the cursor but pressure doesn't work

Pen pressure requires the Accessibility permission. Open System Settings → Privacy & Security → Accessibility, confirm MockTab is listed and toggled on, then quit and relaunch MockTab. If the toggle is already on, try removing and re-adding it.

Also check
Many creative applications (Photoshop, Krita, Clip Studio Paint) have their own internal pressure settings that you must enable independently of the driver. Check each app's brush or stylus settings if pressure works in one app but not another.

Conflict warning in the Devices pane

MockTab shows a notice when it detects another tablet driver running at the same time. Quit or suspend the competing driver, then replug the tablet. The Devices pane status updates when the conflict clears.

Tablet not showing up

If the Devices pane is empty after connecting the tablet, the device may not be in MockTab's registry yet. The Info pane's Collect Device Data button runs a guided capture session that records raw HID traffic and produces a compact summary file. Attach it to a GitHub issue for potential adoption.

Bluetooth not connecting

Bluetooth-capable Wacom tablets (Intuos Pro Gen 2: PTH-460, PTH-660, PTH-860) use Bluetooth Classic, not BLE. Pairing requires a specific sequence. See the Bluetooth pairing section of the Configuration page.

Outside tools to try

If the Wacom driver and MockTab don't resolve your situation, two well-established tools cover a broad range of older hardware and can serve as next steps.

When to choose which tool

Situation Recommended path
Model still on Wacom's supported list but driver won't load Fix permissions per the macOS permission setup section; reinstall the Wacom driver
Model dropped from Wacom's list; want macOS-native settings UI MockTab or Connect my tablet
Dropped model; want free, cross-platform, highly configurable driver OpenTabletDriver
Tablet not yet in MockTab's registry Use Collect Device Data to file an issue, then try OpenTabletDriver as interim
Need step-by-step guided setup with human support contact Connect my tablet (includes email support at enquiry@wptrnpt.co.uk)

Installing OpenTabletDriver on macOS

  1. Uninstall the Wacom driver completely using the Wacom Tablet Utility and restart.
  2. Download the latest release from opentabletdriver.net — choose osx-x64 for Intel or osx-arm64 for Apple Silicon.
  3. Extract the archive and drag OpenTabletDriver.app to your Applications folder.
  4. Launch it from Applications (not from the download location).
  5. Grant Accessibility and Input Monitoring permissions when prompted.
  6. Confirm your tablet appears in the Tablets list. If it does not, check the compatibility table by model number and consult the OTD FAQ.
Note on macOS 26 (Tahoe) permission bug
Tahoe 26.1 and 26.2 contain a known macOS bug that prevents some permission toggles from appearing in the Privacy & Security pane. Follow all prompts carefully and consult the current version of Connect my tablet (v5.7+) for Tahoe-specific workarounds if toggles are missing.

This guide covers macOS-specific troubleshooting. For Windows driver issues, see Wacom's official driver troubleshooting section. Wacom release notes are the authoritative source for supported device lists. Verify current status before installing any driver version.
