Three days ago I mentioned there were new Wacom Product Drivers for Macs. Apparently, there were issues with the release and Wacom has pulled the new drivers from their site.
If you did download and installed the driver, you are probably having problems. You will want to uninstall the new driver and re-install the old driver. The old driver is available at Wacom Drivers.
To correct the problem,
Back up your Wacom preferences
Detach your Wacom tablet from your computer
Uninstall the new driver
Restart your computer
Install the old driver
Reboot your computer
Reconnect your Wacom Tablet
Don’t be mad at Wacom…these things happen…just hold tight and I bet they will put out a new driver soon.
