Why does ToneLoupe need the Screen Recording permission?
Analysing the pixels under the loupe is the product — the permission is how macOS allows an app to read the screen. ToneLoupe analyses frames on the GPU and discards them immediately; nothing is recorded or transmitted. See the privacy policy.
How do I grant (or re-grant) the permission?
System Settings → Privacy & Security → Screen & System Audio Recording → enable ToneLoupe, then relaunch the app. If the loupe ever shows a permission error, the panel has a button that takes you to the right settings pane.
The loupe blocks my clicks — how do I work underneath it?
You already can: the loupe's interior passes clicks through to the app below. Only the border band takes the mouse (outer edge resizes, inner edge moves). The two yellow chips in the top-right corner move the loupe and toggle the scopes panel, and Lock makes the whole loupe click-through.
What do the colors mean?
In Skin mode: yellow = skin sits on the vectorscope skin-tone line; green or pink = hue drifting off it. In Exposure mode, luminance maps to a false-color scale with the skin target on the yellow band and clipping in red — the legend under the scopes shows the full scale.
Which Macs are supported?
macOS 14 (Sonoma) or later, Apple silicon and Intel. Performance cost is roughly 3% CPU at the default 15 fps.
Does it work in fullscreen apps and across Spaces?
Yes — the loupe and panel float above fullscreen apps and follow you across Spaces. The global shortcut (default ⌃⌥⌘S, changeable) hides everything to the menu bar and brings it back.
