How To Turn Liquid Glass Into A Solid Interface is a post from Adam Angst at TidBITS might be worth bookmarking or hanging onto in some form or fashion, at least for a while.

It’s comprehensive in that the post covers what you would need to do to make changes for macOS 26, iOS 26, watchOS 26, and tvOS 26. I say for “a while” because I anticipate Liquid Glass won’t be an issue for some as time rolls on, but there are those who would just rather not use it. Either way, it’s a good reference document to have.
I’ve already posted some of my early thoughts on Liquid Glass and I’ll be posting more as time goes on. My initial views haven’t changed much. Liquid Glass isn’t really to my taste, but I’ll let in it hang around to see how it evolves throughout the year. Frankly, at this point I think Apple has bigger fish to fry in fixing these OS 26 versions.
