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. You can contact Apple tech support by clicking the link at the top of this web page "Get Support". If the above steps are unsuccessful then I don't know of any other fixes and you should try contacting Apple tech support and/or Wacom tech support directly. The above steps are usually successful in restoring Wacom tablet support in macOS Catalina, Big-Sur and Monterey. If you are using a Bluetooth linked Wacom tablet and you have an Intel based Mac then update to Monterey platform, build 12.2.1, released yesterday, Thur 10th Feb 2022, as it has an important fix for the Bluetooth service. Is the tablet now working in your prime user account?

After the Mac has rebooted plug-in or power-on the Wacom tablet.After the files, & have been deleted from the folder " PrivilegedHelperTools" and any Wacom files found in the (possible) folder " Tablet" have been removed, empty the bin and restart the Mac.This folder may not exist on more recent macOS builds, or with more recent installations of the Wacom software. Open that folder, if it exists, and delete any Wacom files that are found there. If your Wacom tablet has been installed for some time, over previous macOS builds, return to the library folder and scroll down the list looking for a folder called " Tablet".If this should occur then restart the Mac in Safe-Mode and repeat from step 4 above, note that in Safe-Mode your mouse commands and keyboard entries will appear "laggy" this is normal for Safe-Mode working, please be patient while repeating steps 4 though 9 in Safe-Mode. If you see the message "unable to delete the file x.x because the file is in use" this means its service is still running.
