I found a solution
For Wacom Intuos 3 PTZ 630
Install 6.3.25 don’t need to restart (all this installers are in the oficial website of Wacom)
Install 6.3.15-3
Before restart:
1- Copy preferences or make a backup with Wacom tablet utility to the desktop
2- Go to library/application support and copy Tablet folder and paste it in the desktop
Click Restart in the installer
When your Mac restarts, double click to WacomTabletDriver the one from the Tablet folder that you pasted in the desktop
IT WORKS FOR ME!
I don't have skills in programming but I hope someone smarter than me could find the way to optimise this action. Let me know if it works for you
