Installation

brew install --cask mpdreamz/tap/yabar

		curl -fsSL https://raw.githubusercontent.com/mpdreamz/yabar/main/install.sh | sh
		
	

Yabar is for Apple Silicon Macs on macOS 15 or later. The cask also puts the yabar command on your PATH, for skhd.

What it needs

yabai, running. Yabar talks to yabai over its socket (/tmp/yabai_$USER.socket). Without yabai, the menu bar still shows your spaces, read from macOS, and Yabar picks yabai up again as soon as it starts.
No permissions of its own. Window titles, frames and focus all come from yabai, so Yabar asks for neither Accessibility nor Screen Recording.
yabai's scripting addition, optionally. Without it, clicking a space focuses one of its windows instead (macOS then switches there), and scratchpads are off.

First launch

Yabar opens at login from its first launch on; turn that off under Settings → General. It updates itself (Updates). Only one Yabar runs at a time: a second copy says so and quits.
