Zed is a fast code editor for macOS, and the easiest way to install it is with Homebrew as a cask - zed.dev 
1. Open Terminal.
1. If you do not have Homebrew yet, install it first - see Installing Homebrew.
1. Install Zed with Homebrew by running this command - zed.dev
brew install --cask zed
4. Open Zed from Spotlight (Cmd + Space, type “Zed”), or run this in Terminal.
open -a Zed
5. Update Zed later using Homebrew.
brew update brew upgrade --cask zed
Optional: If you want the preview build (newer features, more risk), install the preview cask instead - [zed.dev
brew install --cask zed@preview
Optional: If you prefer a manual install, download the macOS build and drag Zed into Applications - zed.dev
If macOS blocks Zed the first time you open it, go to System Settings → Privacy & Security and allow it, then open Zed again.
To uninstall Zed (Homebrew install), run this.
brew uninstall --cask zed
