This is an update to an older question:Is it possible to use old Wacom tablet on 10.11?
I am not allowed to comment on some of the great answers there, so asking as a new question.
I followed the suggestions (answer by @RemBem) and was able to have the Wacom preference pane open using a combination of the most recent supported driver for my Intuos2 tablet and an updated info.plist.
However, most of the preference pane is grey and it is not useful. I wonder if anyone has a suggestion.
Here is what I observe.
The system sometimes also gets into a state where it thinks it needs to restart the System Preferences, but restarting doesn't help and it loops.
