How to set it on your Mac
- Download the image.
- Open System Settings, then Wallpaper, then Add Photo (or drag the file onto the wallpaper list).
- Choose "Fill Screen" - since it is already your native resolution, it stays pin-sharp.
Why the exact size matters
A wallpaper that doesn't match your screen gets scaled and cropped by the system - usually zoomed in, sometimes soft. Every download on this page is cut to 4480 × 2520 with smart focus, so the subject stays centered and each pixel maps 1:1 to your display. Want the untouched original instead? Open any wallpaper and use its main Download button.
