To begin with, you'll want to quit Bluestacks if it's running. This is just to make sure everything goes smoothly. Then, you can head to your Applications folder, where all your apps live. It's like a big app party in there!
Next, find the Bluestacks icon, and drag it to the Trash. This is the part where you say goodbye to Bluestacks. But, we're not done yet! You'll also want to delete any extra files that might be hiding on your Mac.
