Hi folks, I've just purchased a new iMac (Retina 5K, 27-inch, 2019). 3.7 GHz Intel Core i5 64 GB 2667 MHz DDR4 Mac Fusion. Radeon Pro 580X 8 GB When I export files as JPEG/PNG at screen resolution maximum quality, then preview them in Preview, they are fuzzy. When I do the same on my old mac with the same file, it's crisp as. I've spoken to Adobe, Apple and an Apple Tech and no one seems to know what is going on. Has anyone experienced anything similar?
