Big Sur loads the tablets but doesn't register pen input. about wacom-driver-fix HOT 8 OPEN

@isaydesign I can replicate your problem here now too.

My Bamboo touch support was working perfectly after upgrading to Big Sur, but when I removed ConsumerTouchDriver's permission from the Accessibility section, re-adding it and rebooting didn't bring it back to working again.

I'll see if I can figure this out...

EDIT: It turns out that on a Big Sur machine with System Integrity Protection disabled, you can fix the permission issue with the touch support by running these commands:

sudo sqlite3 /Library/Application\ Support/com.apple.TCC/TCC.db 'UPDATE access SET auth_value = 2 WHERE client = "com.wacom.ConsumerTouchDriver" AND service = "kTCCServicePostEvent";'
launchctl unload /Library/LaunchAgents/com.wacom.pentablet.plist
launchctl load /Library/LaunchAgents/com.wacom.pentablet.plist

Now I have to figure out how to do this without disabling SIP, since disabling SIP is both difficult and a bad idea.

@thenickdude just to let you know it works perfectly. Thanks!

When you say the tablet registers the inputs, do they appear in the Wacom tablet preferences if you hold the alt key and click the About button to bring up the tablet diagnostics page? Normally you can see the X and Y coordinates and the pressure changing here as you move the pen.

I have a Touch-enabled Bamboo tablet (CTH-470/K) and everything's fine on Big Sur except for touch input, it doesn't register. Using a tool like Affinity Designer for digital painting, I lost the hability to rotate and zoom the canvas with my fingers, which is super useful. On Catalina everything worked great with your fix.

Update: turns out it does register, but nothing happens. I get readings on all types of touches, and the 3&4 finger gestures work. BUT the cursor doesn't move, and although the icons that indicate zoom and rotation appear, the rotation and zoom don't actually occur.

@thenickdude thanks in advance for your effort.

@isaydesign please try out this new version for me, I believe it fixes touch support on Big Sur now:

(After installing it you'll need to remove ConsumerTouchDriver from the Accessibility list and reboot I think)

Hi there @thenickdude , and thanks for your patch ! I went from no tablet working to a tablet that Big Sur finally reckon, but only with the touch ! Just like @TheElectroclassics. In the about section the X and Y is moving when using the pen, but nothing happens on the screen.
Any idea how to fix this ?
