Another bit of follow-up on squircle jail on MacOS. The most-asked question in my inbox from readers is this: Is mandating the squircle a concession to the much-rumored upcoming touchscreen MacBooks?

No.

The visible shape and appearance of an app icon is unrelated to its clickable — or, perhaps soon, tappable — area. Rendering a visible squircle doesn’t change the shape of the clickable/tappable target area around an icon. In the bygone days when MacOS permitted delicious app icons — and Apple crafted delicious icons for its own apps — you could click in the middle of, say, the QuickTime Player icon and it just worked. It would have been pretty nutty if it didn’t.
