macOS Tahoe 26.3 fixes two annoying design problems [Update: Nope]

Update, 11:10 pm ET: Apple has updated its release notes again. macOS 26.3 does not fix the window‑resizing bug; it is now listed as a known issue.
Apple released macOS 26.3 to the public today, claiming the update resolves two design problems introduced by the Liquid Glass revamp in Tahoe: resizing windows and resizing columns in Finder.
Window‑resizing problem
Many Mac users noticed after updating to macOS Tahoe that windows became harder to resize. Resizing windows is a core interaction, so the regression was widely reported.
In a blog post last month, Norbert Heger detailed what changed in macOS Tahoe that caused the issue. The large rounded corners push most of the clickable resize area outside the visible window boundary, making it difficult 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 px, 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.
Apple’s release notes for macOS 26.3 state: “Window resize areas now follow corner radius instead of using square regions.” In theory, this should make resizing windows easier again.
Finder column‑view issue
The other regression affects the column view in Finder. As Jeff Johnson wrote:
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. On macOS Tahoe, the horizontal scroller covers the resizing widget and prevents it from being clicked!
According to MacGeneration, macOS 26.3 fixes this by repositioning the horizontal scroller under the column‑resizing widget.
Still not perfect
In a follow‑up blog post, Johnson notes that the problem isn’t entirely resolved:
The fix is a step forward, but some quirks remain.
