An alternative icon for kitty, the terminal.

A little CRT-style cat that is like a ghost of other terminal icons.

./build.sh

This downscales kitty-crt.png (1024×1024) into an .iconset and runs iconutil -c icns to produce kitty.app.icns. macOS only (uses sips and iconutil).

Drop the .icns into your kitty config directory:

cp kitty.app.icns ~/.config/kitty/

kitty picks it up on next launch. If the dock still shows the old icon, quit kitty fully and relaunch — macOS caches icons aggressively.

Alternatively, kitty also accepts a plain PNG. If you'd rather skip the .icns step:

cp kitty-crt.png ~/.config/kitty/kitty.app.png

Copy the 256×256 PNG to your icon theme, e.g.:

mkdir -p ~/.local/share/icons/hicolor/256x256/apps
cp kitty-crt-256.png ~/.local/share/icons/hicolor/256x256/apps/kitty.png
gtk-update-icon-cache ~/.local/share/icons/hicolor 2>/dev/null || true
