Windows x64

The executable targets ordinary Intel or AMD x64 Windows. It is self-contained, needs no separate .NET runtime, and requires no ZIP extraction.

Windows may show SmartScreen because this build is unsigned.

If compressed startup or extraction causes trouble, use the behavior-identical Windows x64 uncompressed fallback.

macOS Apple Silicon

This build supports macOS 13 or later on Apple Silicon, not Intel Macs. Extract the archive, move ScreenFix to Applications, then Control-click and choose Open for the ad hoc signed build.

Accessibility permission enables automatic window placement. Masks and calibration continue to work without that permission.

ScreenFix stays on your computer.

The ScreenFix application does not capture the screen, read window contents, use the network, or send telemetry. It observes only the window geometry needed to keep ordinary windows in usable space.

Requirements and limits.

Cartoon Windows and Mac computers working around the same damaged display strip

Windows: The Windows build supports ordinary Intel or AMD x64 Windows. It is unsigned and may trigger SmartScreen.
macOS: The macOS build supports macOS 13 or later on Apple Silicon, not Intel Macs. It is ad hoc signed, not notarized, and may trigger Gatekeeper; Control-click the app and choose Open once. Accessibility permission is required for automatic window placement. Masks and calibration remain available without it.
What ScreenFix does: ScreenFix works around physical display damage; it does not repair the panel or restore dead pixels.
Window limitations: ScreenFix protects ordinary movable windows. It restores ordinary maximized Windows windows into safe space, but administrator windows and protected, custom, fixed-size, non-movable, borderless, exclusive, or full-screen windows may remain unchanged.

Questions before you download.

Can I use only the working part of a broken screen?

ScreenFix can black out a damaged strip and keep ordinary movable windows in the remaining usable space. It does not repair the panel, restore dead pixels, or control every full-screen, protected, custom, or fixed-size window.

Does ScreenFix repair the damaged panel?

No. ScreenFix places an opaque mask over responsive pixels in the damaged strip and manages usable window space. It cannot repair physical panel damage or restore dead pixels.

Which windows may remain unchanged?

Protected, administrator-launched, custom, fixed-size, non-movable, borderless, exclusive, and full-screen windows may be left unchanged. Ordinary movable windows are the intended target.

Why does my operating system warn about ScreenFix?

The Windows executable is unsigned, so SmartScreen may warn. The macOS app is ad hoc signed but not notarized, so Gatekeeper may require Control-click and Open.

When does ScreenFix need macOS Accessibility permission?

Accessibility permission is needed only for automatic window placement. The mask and calibration editor continue to work without it.
