I recently purchased a new MacBook Retina display 13 in. I installed LR3 from my MacBook 15in. This is the second computer that my software is on so it is still under license. When using LR3 in the library mode everything looks fine and normal. However, when I switch over to the develop module, the quality is significantly decreased and I can barely see the image to edit it. When exporting, everything looks fine and normal. What is going on? HELP!!
