This weekend, I was wrapping up a new release of Iris and decided to have some fun after a user emailed to say:
I have a rather niche feature request—but wondering if it would be possible to offer an alternative app icon with the beautiful flower freed from its squircle? I know that Apple has mandated the squircle from macOS Tahoe on; but I’m still running Sequoia, and I imagine other users may be as well. I love the way apps like Nova and Sketch offer alternative “legacy” icons, and it would make Iris feel even more at home in my dock 🙂
We all know about macOS Tahoe’s terrible app icons and how 3rd party developers have been confined to squircle jail.
If you’re lucky enough to distribute an app outside the Mac App Store, you can break free of squircle jail using NSDockTilePlugIn. It’s not strictly the intended use-case of that API. And it’s not allowed in the Mac App Store, either. But it can solve the problem.
