Upgrading to Mac OS 10.14 Mojave? A new driver will be released early this week. Keep an eye out in the Wacom Desktop Center for the update notice. However, a new Mac OS security feature requires some additional changes to run the Wacom Driver correctly. Please see the instructions found on our support page here:

Intuos Photo - Pen jittering everywhere (CTH490)

Postby cassiel » Wed 3. Jan 2018, 19:16

My brother recently bought an Intuos Photo CTH490 tablet, and has connected it to his computer and downloaded drivers etc.

The problem is that it is impossible to draw a straight line without the cursor jerking to the side, creating what looks like a line with a dent in it. We have tried this many times, even using a ruler in real life to check that it is not just his hand being wobbly or some other external factor.

We have scoured the internet for an answer but haven't found anything. We've tried redownloading drivers, downloading old drivers, changing all the settings, but to no avail. It does the same thing in Photoshop as it does in e.g. Paint.

One thing we have also noticed is that when you open the "Wacom Tablet Properties" window, the only things visible are Application: All other, Photoshop. The "Device:" and "Tool:" options do not exist.

If anyone could help with this we would be very grateful!

If tablet and tool are empty in control panel, the driver did not recognize the tablet for some reason. Assuming you are using some version of Windows I suggest to check first for problems in device manager and resolve them. Make sure to connect the tablet to a USB port in the back of the machine directly (not through a hub) and if possible use a USB2 port. If all looks ok in device manager, go to Wacom Desktop Center -> Backup Settings -> reset settings, so that the driver resets the connection and searches again for the correct tablet model.
