macOS Tahoe 26.3 Resolves Two Major Design Flaws

Apple has released macOS 26.3, addressing two significant design flaws that emerged with the Liquid Glass redesign in Tahoe. Users have reported difficulties with resizing windows and adjusting column sizes in Finder, rendering essential tasks cumbersome.

Key Improvements in macOS 26.3

This update focuses on enhancing user experience by fixing two critical issues:

• Window Resizing: Many users found it increasingly challenging to resize windows after updating to macOS Tahoe. The new design featured large rounded corners, which pushed the clickable areas for resizing outside the visible window boundaries. Users keen on resizing often clicked in areas that did not register the action.
• Finder’s Column View: The column view in Finder faced usability problems due to a horizontal scroller obstructing the resizing widget. This made it difficult for users to adjust column widths comfortably.

Resolution of Design Flaws

In his blog post, Norbert Heger noted that users’ instinctive clicks were misaligned due to the rounded corners. He observed that, although an area of 19 × 19 pixels was designated for clicks in the window corners, approximately 75% of this area was outside the window. Apple has now adjusted the window resize areas to follow the corner radius, theoretically simplifying the process of resizing windows.

In addition, the macOS 26.3 update has repositioned the horizontal scroller in Finder so that it no longer interferes with the column resizing widget. Jeff Johnson, a macOS user, highlighted this ongoing challenge but acknowledged the update as a step in the right direction.

Conclusion

Overall, macOS 26.3 delivers essential fixes for significant design flaws that affected user interface interactions. As users adapt to the changes, they can expect improved functionality when working within Mac applications.
