I have a new Imac "3,5 GHz Intel Core i7" and working with photoshop cs6, on a new installed mac.
When I turn OPENGL on, what ever possible way , normal , basic advantaged. It freezes my keyboard.
So when I'm brushing I can't switch whit x to turn back and foreground color, or reduce en enlarge the brush size.
I only have to switch manual between my tools and then it works again, until the next 3 or 4 minutes.
But When I turn the OpenGl options OFF (and restart the program.) It works????
O, and Yes I followed the :
Photoshop: Basic Troubleshooting steps to fix most issues
But it slit is there.
When I use an older Photoshop it works fine.
