Got it, I totally get the frustration of digging through Applications to launch Docker every time—here's how you can fire it up straight from your terminal:

• Basic command to launch Docker Desktop
  Use macOS's built-in open tool to kick off the GUI app. Run this command:

  open -a Docker
  

  This works exactly like double-clicking the Docker icon in your Applications folder. You'll see the Docker menu bar icon pop up once it's ready, and you can immediately run any docker commands afterward.

• Launch Docker Desktop quietly in the background
  If you don't want the main Docker Desktop window to pop open when starting it, add the -g (background) and -j (minimize to Dock) flags:

  open -gj Docker
  

  Docker will run silently in the background, with only the menu bar icon indicating it's active.

• Check if Docker is running properly
  To confirm the Docker daemon is up and ready to accept commands, run:

  docker info
  

  If you get a detailed output about your Docker setup instead of an error message, you're all set to use Docker via the command line.
