At WWDC, Apple announced its new Liquid Glass design language, which is coming to all of its devices, including Macs. I’ve been tinkering with the macOS Tahoe 26 developer beta on the M4 MacBook Air for about a day. So far, the aesthetic changes range from slick to slightly overwrought, but the new Spotlight search features are nifty and useful.

It's true that the Liquid Glass redesign is less than revolutionary, but at least with macOS 26, with it, Apple is making users be more productive.

Finally, macOS Tahoe introduces Metal 4, the next-generation version of Apple's proprietary graphics API. The big new feature in Metal 4 is "frame interpolation," a feature similar to Nvidia's DLSS Frame Generation that will attempt to smooth frame rates by using AI to generate frames that it can insert between frames that the GPU actually renders.
