Whew. Those screenshots: https://arstechnica.com/gadgets/2025/09/macos-26-tahoe-the-a... As a KDE Plasma dev, I always counted on us getting better, but I didn't expect the competition to get so much worse. We'd be flamed to high and heaven for shipping broken notification popups and rendering glitches like that in a prod release. What happened internally to cause this, I wonder?
As for what happen at Cupertino: it seems that they replaced people who knew theory and practice, principles of interface design with designers who were told to make a product that looks "fresh" and will diverge attention from Apple's AI failure.
Because why this Liquid Glass now if not as "rattling keys" effect? It's not a technological breakthrough - we've seen translucent plastic/glass/acrylic elements and fancy animations in operating systems before. Hell, even Plasma had that glass stuff in initial line 4 of release. And OSX had Aqua interface, window animations long before Microsoft wasted years for Longhorn finally releasing it as Vista with Aero. Not mention Compiz on Linux around same time.
My partner is already baffled with lack of polish and consistency across the system in this release. In some places it's just a transitional animation added on top of flat style for "wow" effect because hardware nowadays doesn't tax much for that. Tahoe feels like it tries to follow GNOME/Adwaita big interface elements that should stay exclusively on mobile devices, and it does this quite late and also really bad.
