Update (11:10 PM ET): In a frustrating turn of events, Apple has updated its release notes again. The company now states that macOS 26.3 does not fix the window resizing bug. Instead, it has been moved back to the list of “known issues.”
Apple released macOS Tahoe 26.3 to the public today. The update was originally touted to fix two major design frustrations introduced by the new “Liquid Glass” UI revamp in Tahoe: the difficulty of resizing windows and broken column resizing in Finder.
While one issue seems to be resolved, the other remains a thorn in the side of Mac power users. Here is the breakdown of what has changed (and what hasn’t) in the latest build.
The Window Resizing Saga
One of the most vocal complaints since the launch of macOS Tahoe has been the difficulty in grabbing window corners to resize them. For such a critical, everyday interaction to feel “broken” was unacceptable to many.
In a detailed blog post last month, developer Norbert Heger explained exactly why this was happening. The issue lies in the geometry of the new “Liquid Glass” design language:
- The Problem: The active “click area” for resizing a window is a 19×19 pixel square at the corner.
- The Design Flaw: Because Tahoe introduced massive rounded corners, approximately 75% of that clickable area now lies outside the visible window boundary.
- The Result: Users instinctively click the visible corner, which is technically a “dead zone,” leading to missed clicks and frustration.
The Status: Initially, Apple’s release notes claimed: “Window resize areas now follow corner radius instead of using square regions.” Theoretically, this would have solved the issue. However, with the retraction of this note late last night, it appears users will have to wait for macOS 26.4 for a proper fix. You can track known issues on the Apple Developer Documentation page.
The Finder Column Fix
The second major design flaw addressed in 26.3 involves the Finder. Long-time Mac users who prefer “Column View” (a feature dating back to the original Mac OS X) noticed that the horizontal scroll bar was overlapping the column resizing widget, making it impossible to adjust column widths.
Developer Jeff Johnson highlighted this UI regression, calling it a “monstrosity.”
- The Fix: As spotted by MacGeneration, macOS 26.3 finally addresses this. The horizontal scroller is now properly layered under the column resizing widget, allowing users to click and drag without obstruction.
- The Catch: In a new post today, Johnson noted that while functional, the implementation is still not perfect, calling it “baby steps” in correcting the Finder’s behavior.
Recommended Mac Accessories for 2026
While software updates sort themselves out, having the right hardware can improve your workflow.
- Logitech MX Master 4: The precision of this mouse can help mitigate some of the UI targeting issues in Tahoe.
- OWC Thunderbolt 5 Hub: Essential for the new high-bandwidth Mac architecture.
- Twelve South BookArc: Perfect for keeping your desk clutter-free while running Clamshell mode.
Conclusion
The release of macOS Tahoe 26.3 is a mixed bag. While it successfully patches the embarrassing Finder column overlap, the retraction of the window resizing fix is a disappointment for users struggling with the new Liquid Glass interface.
It serves as a reminder that even in mature operating systems, UI changes can have unforeseen usability consequences. Users experiencing these interface glitches are encouraged to submit reports via the Apple Product Feedback portal to ensure they are prioritized for the next point release.
