In System Preferences > Wacom Tablet drivers don't appear. There were two more ways for possible solution, which don't seem to be working here: dealing with NVRAM (Option+Cmd+P+R after reboot – didn't help) or SMC (doubt, this could help in this sit.) I also tried to use older drivers instead of the newest ones: the result is the same. Restarting iMac and installing the drivers again. I also tried removing all the drivers, and deleting all the Wacom Tablet files inside Libraries, LaunchAgents, PriveledgedHelperTools, etc. The curious thing is that I created a New User and in this case the Tablet does work, but not with the Admin Account. Important thing: I asked the Wacom Support about this issue and we tried a few options, but to no avail. The tablet itself works fine (lights on).

I tried the tablet 5-6 months ago and it worked fine then, but as I've plugged it again via USB now, iMAC simply doesn't see it. Wacom Tablet driver works on New User only (and not on Admin) Hi, everyone! I recently reconnected WACOM Intuos Small PTH-451 tablet to my iMac and it wouldn't work even after (re)installing the drivers.
