He ejoystick,
Not sure with third party tablets other than Wacom but is your tablet recognized in System Preferences?
This Mac "Help" topic concerning Ink technology pertains to using a Wacom tablet so I'm not sure it is relevant to a Genius tablet:
Writing text with your graphics tablet
If you have a graphics tablet and stylus, you can use Ink technology to write >text that your computer recognizes and turns into words. You can write anytime >you're using your stylus, in your own handwriting. You can also use Ink to draw >a sketch and insert it in any document that can display pictures.
With Ink you can use your stylus to write menu commands and keyboard shortcuts, >allowing you to control your computer without using the mouse or keyboard.
When you have a Wacom graphics tablet connected to your computer, and the Wacom >tablet software installed, the Ink icon appears in System Preferences. Turn on >handwriting recognition, then click the Help icon on the Ink toolbar for more >details.
I tried looking on the Genius website support pages and I couldn't find a 4600 but only a 4500 listed.
Also, you list 10.1.x as your OS in your computer's specs below your post but in your topic title you state you are using 10.2.8. This may make a difference to the answer you receive depending upon the system requirements that the tablet requires.
sorry and I hope that helps some,
littleshoulders 🙂
