Mac OS: Cursor's Position is Off-Target

If after reinstalling ZBrush you notice that the cursor position is offset from where you are clicking, for example appearing approximately 1/4 inch away from the actual click location, the issue is typically related to either:

• A window scaling or header duplication issue
• Residual macOS application state files from a previous installation

First Check for a Double Header

In some cases, ZBrush may display a duplicated window header bar at the top of the application window. If this is present, the cursor offset is caused by macOS window scaling behavior. Fully closing and relaunching ZBrush usually resolves it. If the double header persists, restart the system.

If there is no double header visible, continue with the steps below.

Proper Uninstallation on macOS

On macOS, simply dragging the ZBrush application to the Trash is not a complete uninstall. Doing so may leave behind preference files and saved application state data that can interfere with future installations.

To properly remove ZBrush:

1. Close ZBrush.

2. Open the Applications folder.

3. Locate ZBrush.

4. If an Uninstall application is included inside the ZBrush folder, run it.

If no uninstaller is present, proceed with manual cleanup as outlined below.

Remove Saved Application State Files

1. In Finder, hold the Option key and click Go in the menu bar.

2. Select Library from the dropdown menu.

3. Navigate to:
   ~/Library/Saved Application State/

4. Delete any folders related to ZBrush or Maxon. These may include names containing:
   com.maxon.zbrush
   com.pixologic.zbrush (legacy installations)

You may also check and remove ZBrush-related folders from:
~/Library/Preferences/
~/Library/Application Support/Maxon/

Be careful not to remove unrelated files.

Reinstall ZBrush

After removing the saved state files:

1. Restart your Mac.

2. Reinstall ZBrush using the Maxon App or the official installer.

3. Launch ZBrush.

The cursor alignment should now function correctly.

If the issue persists, verify your macOS display scaling settings under System Settings > Displays and ensure the resolution is set appropriately for your monitor.
