There are new drivers available from Wacom. It appears that I missed the ones posted on 10/15/13 for Macs. There is a new set posted on 12/10/13 for Window Users. The drivers are for Cintiq Companion Products, Cintiq Products, Intuos Pro, and Intuos. There is a driver posted 12/19/13 for Bamboo Tablets. Like I said, all the ones posted in December are for Windows users, the October posts are for Macs.
I did update to the latest driver because I was having a couple of issues and I am on an Intuos 5. If you are not having issues, I’m not sure you would need to update your driver if you are on an older tablet.
Don’t forget to back up your preferences before you uninstall and install.
