Hello, I'm using photoshop CC on amacbook pro retina. I mainly use photoshop for web design and when I open a document that is 300x200 px, the 100% view is too small on screen. Any ideas, It was this way on PS cs6 also before I upgraded. I just tried to delete the prefs file and restarted PS and it did not change. I have also tried to change my screen resolution to "best for retina" and it is still the same.
