Apple has released macOS 26.3, and the update quietly fixes two frustrating design problems introduced with the Liquid Glass redesign in macOS Tahoe.
Credit goes to MacGeneration for spotting the fixes early in the betas.
Window resizing is finally fixed
After upgrading to macOS Tahoe, many users noticed something felt off: resizing windows became harder.
The issue stemmed from Tahoe’s large rounded corners. While visually appealing, they pushed much of the clickable resize area outside the visible window boundary.
Developer Norbert Heger previously explained that macOS expected clicks within a 19×19 pixel square near the corner. With Tahoe’s exaggerated corner radius, about 75% of that area ended up outside the window’s visible shape. The result was inconsistent and frustrating resizing.
In the macOS 26.3 release notes, Apple confirms the fix:
“Window resize areas now follow corner radius instead of using square regions.”
That means resize detection now matches the actual rounded shape of the window. In practice, resizing should feel normal again.
Finder columns view bug resolved
The update also fixes a broken behavior in Finder’s Columns view.
As previously highlighted by developer Jeff Johnson, the horizontal scroll bar in Tahoe overlapped the column resizing widget. This made it impossible to click and adjust column widths properly.
macOS 26.3 corrects this by repositioning the horizontal scroller underneath the resizing control.
macOS 26.3 doesn’t bring flashy new features, but it fixes two core usability issues introduced by Liquid Glass:
- Window resizing works properly again
- Finder Columns view resizing is restored
If Tahoe made your Mac feel oddly clumsy, this update should restore expected behavior.
