I just bought a new iMac (fall 2019. When I set the thumbnail view option at its maximum size 512x512) the thumbnails I see in the finder are blurred and have jagged details. Is there any way to get the thumbnails to display properly?
I just updated to Catalina and immediately noticed finder thumbnails were severely pixelated. Double click and open in Preview they are perfect. Hopefully somebody has a solution because it is important to see them properly in Finder when screening a folder of pictures.
