CornerFix (macOS)
Visually square the rounded display corners in macOS 26 (Tahoe) and newer by drawing unobtrusive, click‑through overlay caps.
Note: This does not change the rounded corners of individual app windows. It only restores the straight silhouette at the edges of your display.
Why CornerFix?
Apple made corners more aggressively rounded in macOS 26, and many users find the effect distracting. There’s no system setting to disable it. CornerFix provides a safe, non-invasive way to visually bring back sharp edges without hacking system files.
