Apple’s newest macOS 26 release – internally known as “Tahoe” – has prompted a wave of criticism from longtime users and interface designers over an unexpected usability issue: resizing windows has become noticeably more difficult. The problem stems from the operating system’s shift to a new rounded visual style, which inadvertently pushes the resize interaction zone outside the visible window.
At the core of the controversy is the 19×19 pixel invisible hit area used by macOS for detecting resize actions. Earlier macOS versions featured sharper corners, ensuring most of that hotspot sat inside the window boundary. With the much larger curvature introduced in Tahoe, a majority of that zone now sits outside the corner, where users rarely click. As a result, dragging from inside the window often fails, while dragging from the empty space beside it unexpectedly works.
Interface specialists say the change breaks established muscle memory built over decades of desktop computing. It also arrives after years of Apple removing overt resizing indicators – the textured corner handle disappeared with the Lion release in 2011, forcing users to rely solely on invisible hotspots and cursor changes.
For many, this latest shift pushes invisibility too far, prioritizing aesthetic themes over user control. Commentators argue that Apple’s once-famous philosophy of “design as function” risks being overshadowed by ornamental decisions, especially in an era when desktop productivity remains central to macOS users.
Developers have published diagrams demonstrating how the geometry fails under the new corner radius, calling it an issue unlike anything seen since the early graphical interface era. Some users have adjusted by keeping apps maximized or by slowly scanning for the resize trigger, but the consensus is that the behavior should be addressed by Apple rather than normalizing awkward workarounds.
Possible remedies include enlarging the hotspot, repositioning it to sit fully inside the window boundary, or restoring visual affordances. As of now, Apple has issued no guidance or timeline for a correction. Until a fix arrives, those upgrading to Tahoe should expect a brief learning curve – and occasionally, a few misplaced clicks.
