Zoomer

Zoomer is a macOS tweak that replaces the native "Fullscreen" (Green Button) behavior with a "Zoom to Display" action. Maximize as it should be!

Installation

make install

Usage

Simply click the green button on any standard macOS window to zoom to display size. Click again to return to original size before zoom.

To enter native Fullscreen, hold the Option (CMD) key and click the green button.

Uninstall

make uninstall

Requirements

• macOS (tested on Tahoe)
• Ammonia injection system installed (requires SIP disabled)

System Security Settings

For Ammonia injection to work, System Integrity Protection (SIP) must be disabled.

How It Works

• _zoomButtonIsFullScreenButton: Swizzled to return NO (Zoom) unless Option is held.
• zoom:: Swizzled to maximize window width to the screen's visible frame.
