The Shape of Apps ⇥ parakeet.co

Paul Kafasis, writing on the Rogue Amoeba blog:

With last year’s release of MacOS 26 (Tahoe), Apple made a mess of app icons. In the first betas of MacOS 27 (Golden Gate), however, there are signs of a turnaround. We’re urging Apple to continue making improvements, by restoring the ability for MacOS app icons to have distinct shapes.

Kafasis reignited my simmering frustration with the mandated squircle in MacOS. My Dock contains three of the apps shown in the collection in this post: MarsEdit, NetNewsWire, and Sketch. I like their current more-uniform icons fine enough, but they are less distinguished than the ones these applications used to have.

But maybe that is the whole point?

Louie Mantia, writing on the Parakeet blog:

The shape of apps is a squircle. And it has been proven to work for everyone. Companies can use their logo as an app icon. Designers can create something specifically for the platform. And both of these get to look like an app. Whether people consider the squircle a container or a canvas, this uniform appearance communicates its function: a squircle represents an app, just like how a piece of paper represents a digital document, or a folder represents, well, a folder.

Semantically, there’s something really beautiful about that. As an icon designer, I appreciate that different types of things have visual distinction.

Mantia touches on all the pragmatic reasons to unify the shape of icons in an operating system, all of which I have considered, and then drops the above paragraphs — and things started to make more sense to me. This is a different way to think about it. This is not a situation where a cleaner looks like a zesty beverage with toxic consequences. The shared general function of these icons does help communicate something and makes them less ambiguous in that sense.

But a broad category of functionality is only part of the story of an icon and — with respect to Mantia’s long and illustrious history of work in this area, and that of co-Parakeeter Luka Grafera — taking away a difference of shape also limits what an icon can communicate. It may not be a cleaning product that looks and is packaged like juice, but imagine if every consumable liquid was in identical bottles with only a different label. You might go for something refreshing after a workout and end up drinking soup. Sure, you can argue the label for a beverage should not look similar to the one for soup, but the two would be far easier to distinguish if they were not in the same package.

I still think constraining designers to a singular shape, while more clearly defining specific objects as apps, has made it harder to distinguish between them, particularly when combined with the glassy and contrast-killing layer effects of Tahoe. Happily, though not retreating on the squircle, the shapes within icons in MacOS Golden Gate are at least more clearly defined.
