Wacom gd-0912-u not working with mac pro 10.6.8

The first thing you have to do is upgrade your Windows from version 8.0 to 8.1. Version 8.0 just has too many bugs plus it shouldn't automatically update anymore Check this MS page out.

Install the latest Windows 8 1 Update Windows Help


Here are the bare bones manual installation steps from the page:
Install the update manually

Make sure your PC is plugged in and connected to the Internet using a non-metered connection. Don't disconnect, unplug, or turn off your PC while the update is being installed.

Swipe in from the right edge of the screen, tap
Settings, and then tap Change PC settings.
(If you're using a mouse, point to the lower-right
corner of the screen, move the mouse pointer up,
click Settings, and then click Change PC
settings.)

Tap or click Update and recovery, and then tap or click
Windows Update.

Tap or click Check now.

If updates are found, tap or click View details.

In the list of updates, select the update containing
KB 2919355, and then tap or click Install.

If you're prompted for an administrator password or
confirmation, enter the password or provide
confirmation.

After the installation is complete, restart your PC and
sign in.

Note: If you don't see KB 2919355 in the list of available updates, you might be missing one or more required updates. Follow the previous steps to check for updates, install all important updates, particularly KB 2919442, restart your PC, and then check for KB 2919355 again.

Once you successfully update to Windows 8.1 we can tackle your Wacom products. There have been plenty of documented problems getting the Wacom Intuos Drivers working in Windows 8.x. Just google on "Wacom Intuos Driver Windows 8.1"

First get the latest Intuos driver version from the Wacom website.

I couldn't find any separate drivers for the Wacom mouse

Since you are running Windows Vista on your PC this is the driver you should have downloaded.

Click Here

Serial cables are not hot swappable. The computer and tablet should be turned off before you plug them in.

you can force windows 8 to use windows 7 drivers, you just need to force it to accept it, unzip to a folder and point to that folder.

I think this is what you are looking for: http://www.wacom.com/en/CustomerCare/Drivers.aspx?model=Intuos2&os=Windows+XP

Download at the wacom software site:

I had the same good results. Just clicked on Intros and Windows 7 to download the driver fro my model GD -0608-U tablet

hello, just go on the wacom site and download the newest drive for mac os x, i was having similar problems, but now everything's fixed and it's working fine!

go to the following link,

Try unplug bamboo tablet,repair permissions, intall newest driver from web page , run repair permissions again and plug bamboo, it should be it.

check ebay

Hi know this is some months on but have just read your article! If you haven't solved this problem it may be something to do with having the incorrect driver. You could look up Wacom's website as they detail driver codes in relation to the Model No. of the tablet. 
Also you might try disconnecting your usb cable after booting your mac, I've noticed myself that sometimes my tablet and mouse is not recognised (I'm using OSX10.4.9 on a G5 dual) but after unplugging the USB cable and plugging it back in it works fine, so this may be just some kind of bug that hasn't been fully addressed in the actual driver software itself? Anyway I hope this helps in some way, good luck!
