Zoomed image grays out and outlines beyond 400%

Hello everyone,

I began work on a new Mac and never encountered this problem on previous Mac/Illustrator installs. Once I zoom beyond 400% the image grays out and only the selected objects outline is visible. This has happened from day one. I have worked around it but, I need to zoom in closer for more detailed areas. Anyone seen this before?
