Screen Recording permission. The whole-screen eyedropper picks a background colour by sampling your displays, which uses screen capture — so macOS will ask for Screen Recording permission the first time you use it. The app captures nothing until you invoke the eyedropper, and never transmits anything.
How spanning works on a Mac. macOS gives every display its own desktop picture, so Wallpaper Spanner composites one image across all your screens first, then writes each display's slice. The result is still one continuous scene.
What you get in Free
The complete alignment product: unlimited monitors, automatic physical-size matching, the measure-for-exact-fit wizard, the live alignment test, one-pixel positioning, bezel control in px or mm, all seven layouts, multi-photo collages, full-resolution output, and one saved scene. No ads, no watermark, no account.
Upgrading to Plus
Plus adds drawing tools, unlimited saved scenes, and scheduled scene rotation for a one-time $5.99 (launch price; $7.99 after). Buy it from the Free vs Plus section — your licence key arrives by email and activates inside the app.
