With my Intuos1 tablet, in my case this was version 6.2.0w4 I managed to get a working Wacom Preference Pane with the following trick/steps:Дownload the old driver that works. Unfortunately this does not work anymore in High Sierra. The solution for a working Preference Pane for previous MacOS versions was to open System preferences in 32-bit mode, as described in this thread.The above works, you have a working tablet, but without a working Preference pane in System Preferences, as described in this thread. Then import/restore these setting with the same Wacom Tablet Utility.

Using a legacy driver, in my case 6.2.0w4, downloadable on the Wacom website:Д®xport/backup the Wacom preference file from my pre- High Sierra (Mountain Lion in my case) computer/backup with the right settings, with the Wacom Tablet Utility in Applications > Wacom-tablet. I read all solutions in this and other threads.ДЇirst, the following steps got me a more or less working tablet, as described in this thread: I have an old first Wacom Intuos first generation (GD-0912-U) tablet, and ran into the same problems as described above, after I upgraded to High Sierra from Mountain Lion.ДЄfter a lot of reading and trial-and-error, I now have a fully working old Wacom tablet, with a fully working Wacom preference pane in System Preferences. Then switched System Preferences to 32bit and back, opening the prefpane before, in between and after. I managed to get my Wacom Intuos GD-0912-U (first generation Intuos A4 size) tablet working in High Sierra, with a fully functional Wacom Preference Pane, by using a newer driver and preference pane, and hacking the preference pane file: I replaced the ist in the package of the newer preference pane (6.3.15-3) with the ist from the old preference pane (6.2.0w4) that was working in older macOS.
