The latest apple iMac’s and MacBook Pro’s have truly impressive screens reaching up to 5K resolution on the retina display of a 27 inch iMac, that’s 5120 by 2880 pixels (or 4096×2160 for the 4K display on the 21.5 inch iMac)! For your wallpaper on one of these retina displays you’ll want to make use of every last pixel! The wallpapers below do just that! They all measure 5210×2880 pixels (5K), so even on Apple’s best display all pixels will be utilized. But they’ll look great on anyone of your Mac display backgrounds, whether they are of the MacBook, iMac, Mac Pro/Mini, iPad or iPhone variety.
