Pinch to zoom works everywhere except the one window full of pictures
Preview, Photos, Safari, Maps, Quick Look — pinch zooms. Finder's icon view, a grid of thumbnails, ignores it. It used to work. Apple took it out.

A Finder window in icon view is a grid of thumbnails — the most zoom-shaped content on the machine. You pinch. Nothing happens.
Pinch works in Preview. In Photos. In Safari. In Maps. In Quick Look — which is the same thumbnails, one keypress away. It works on the desktop with a modifier. It does not work here.
A removed gesture is worse than an absent one
This isn’t an oversight; the gesture used to work and was taken out. That changes the character of the failure:
- Learned behaviour gets invalidated. Everyone who built the habit now has a reflex that silently fails in one place. They didn’t get it wrong — the ground moved.
- A dead gesture gives no feedback. A button that does nothing is at least visibly a button. A pinch that does nothing is indistinguishable from a broken trackpad, a frozen window, or your own bad technique. You try again, harder, before concluding anything.
That ambiguity is the real cost. The user can’t tell a deliberate omission from a fault, so they debug instead of adapting.
The principle
A gesture that means one thing everywhere must mean it everywhere. Platform conventions are a contract: the OS teaches pinch = zoom across a dozen apps, and every exception is a small tax charged to everyone who believed the lesson. Consistency is worth more than any local justification for breaking it — and there’s no obvious local justification here, since resizing icons is exactly what pinch would mean.
The math
60M Mac users × 12 attempts/yr × 8s = ~3 lifetimes / year
Meanwhile, what does work
- ⌘= and ⌘− resize icons in Finder.
- The slider in the bottom-right of the window in icon view.
- ⌘J opens View Options with an icon-size slider, per folder.
- On the desktop, holding right-click while sliding two fingers resizes icons.
Four separate mechanisms for the thing one universal gesture would have covered — which is itself the tell that the gesture belongs here.
Version-dependent. Pinch-to-zoom in Finder has come and gone across macOS releases, and some sources describe a trackpad or Finder setting that re-enables it. The exact removal point and whether any official toggle survives should be confirmed against current macOS before this is quoted. The stable observation is the inconsistency: pinch zooms in Apple’s own image-viewing apps and not in Apple’s own image-grid view.
Difficulty to fix: none
The gesture handler exists throughout the operating system. The content is thumbnails. The intent is unambiguous. Reconnect the wire.
