Hello XP-Pen Team,

I recently purchased an XP-Pen Deco 01 V3 tablet for handwriting and note-taking on my MacBook Pro.

I encountered an unusual issue with the macOS driver and would appreciate clarification from the engineering team.

System configuration:

• MacBook Pro 16-inch, Apple M4 Max, 36 GB RAM
• macOS Golden Gate 27.2.1
• Tablet: XP-Pen Deco 01 V3
• Driver: XPPenMac_4.0.21_261026

Issue 1: Complete system freeze

The tablet works correctly after installing the driver and granting the requested macOS permissions.

However, when I navigate to System Settings → Privacy & Security → Device Control and Data Access and attempt to disable XPPenDriver, my entire MacBook freezes.

The keyboard and mouse become unresponsive, requiring a system restart.

I have reproduced this issue multiple times. My MacBook had not experienced similar freezes during approximately one year of use before installing the driver.

The freeze occurs specifically when disabling this permission, not during normal tablet operation.

Issue 2: Clarification regarding permissions

My primary requirement is handwriting and note-taking.

I noticed that the driver requests Device Control and Data Access, Input Monitoring, and Accessibility permissions.

I understand that certain permissions may be required for pen input, pressure sensitivity, and shortcut functionality.

However, I would appreciate clarification about why Device Control and Data Access is necessary for basic writing.

Questions for the technical team:

1. Is this a known issue with the current macOS driver?
2. Has driver version 4.0.21 been tested with Apple M4 Max and macOS 27.2.1?
3. Which tablet functionality specifically requires Device Control and Data Access?
4. Is there a supported method to disable these permissions safely after disconnecting the tablet?
5. Is a driver update planned to address this behavior?

Current status:

I have uninstalled the driver using the official uninstaller and restarted my MacBook. No XP-Pen background processes are currently visible.

I have also contacted XP-Pen technical support by email.

I would appreciate technical guidance from XP-Pen engineers or other Mac users who have experienced similar behavior.

Thank you.
