macOS Tahoe 26.3 fixes two annoying design problems

Source: 9to5Mac

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.

Window‑resize fix

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 actions on a Mac, so a break in this critical UI element was unacceptable.

In a blog post last month, Norbert Heger detailed what changed in macOS Tahoe to cause the problem. Essentially, the large rounded corners pushed most of the clickable resize area outside the visible window boundary, making it nearly impossible to grab consistently.

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 26.3, Apple writes:

“Window resize areas now follow corner radius instead of using square regions.”

Theoretically, resizing windows should now be a lot easier.

Finder columns fix

macOS Tahoe 26.3 also fixes the broken columns view in Finder. Jeff Johnson wrote that the horizontal scroller in the columns view covered the resizing widget, preventing 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.
