CLI: brew install requires --no-quarantine to bypass unsigned casks

[eamansour]

Story

As a Galasa user, I want to install the CLI without bypassing any security checks, so that I can install the tool safely.

Background

The documentation for installing the Galasa CLI tool mention using --no-quarantine to install galasactl via homebrew. However, this flag no longer works and instead, users need to run the following command:

xattr -dr com.apple.quarantine galasactl

We should find a way to sign the galasactl binary so that we could simply run:

brew tap galasa-dev/tap
brew install galasactl

Tasks

• Implement the changes needed to sign the galasactl binary in the homebrew/galasa repo
• Update the documentation site to remove the use of --no-quarantine
