macOS Tahoe 26.3 fixes two annoying design problems

Apple released macOS 26.3 to the public today, and the update fixes two design problems introduced by the Liquid Glass revamp in Tahoe: resizing windows and resizing columns in Finder.

One thing many Mac users noticed after updating to macOS Tahoe was that it was harder to resize windows. Resizing windows is one of the most common things people do on their Mac, so for such a critical user interface element to break was unacceptable.

In a blog post last month, Norbert Heger detailed what exactly changed in macOS Tahoe to cause this problem. Essentially, macOS Tahoe windows are hard to resize because they aren’t really rounded.

macOS Tahoe’s large rounded corners pushed most of the clickable resize area outside the visible window boundary, making it nearly impossible to grab consistently.

As Heger explained in the blog post:

Since upgrading to macOS Tahoe, I’ve noticed that quite often my attempts to resize a window are failing. This never happened to me before in almost 40 years of using computers. So why all of a sudden?

It turns out that my initial click in the window corner instinctively happens in an area where the window doesn’t respond to it. The window expects this click to happen in an area of 19 × 19 pixels, located near the window corner. If the window had no rounded corners at all, 62% of that area would lie inside the window.

But due to the huge corner radius in Tahoe, most of it – about 75% – now lies outside the window.

The good news is that Apple says macOS Tahoe 26.3 solves this problem.

In its release notes for macOS Tahoe 26.3, Apple writes: “Window resize areas now follow corner radius instead of using square regions.” Theoretically, this means resizing windows should be a lot easier now.

macOS Tahoe 26.3 also fixes the broken columns view in Finder. Last month, Jeff Johnson wrote the following on his blog:

Finder has four view modes, represented by the four consecutive toolbar icons in the screenshot below, if you can even call that free-floating monstrosity a toolbar anymore: Icons, List, Columns, and Gallery. My preference is columns view, which I’ve been using for as long as I remember, going back to Mac OS X.

At the bottom of each column is a resizing widget that you can use to change the width of the columns. Or rather, you could use it to change the width of the columns. On macOS Tahoe, the horizontal scroller covers the resizing widget and prevents it from being clicked!

As spotted by MacGeneration, macOS 26.3 fixes this problem. The horizontal scroller is now properly positioned under the column resizing widget.

Progress.
