In what way are you loading images? You can definitely request images that are 2x the size in width and height. However, depending on how you are displaying the images, I think there are special steps you need to take for retina macs.
Thanks for the quick response. I think we got it sorted now. By the way, at some point, we saw a watermark on the radar images. I'm not sure I'm seeing them still but is there a flag or something we need to apply to ensure that doesn't happen in production?
