Issue: When you try to use "remotebuild" through the Terminal app, it prompts for you to install Homebrew and requesting for admin credentials.
Solution: Simply select "n" (no) to refuse installing Homebrew. Homebrew is already installed on all Managed Servers so you do not need to install it again. After you selecting "n" to reject the Homebrew installation, "remotebuild" should start properly on default port 3000. You may also start "remotebuild" on other ports such as 3001, 3002 etc. using:
remotebuild --port [alternative port number]
