Bluestacks is an Android emulator, which is to say, a program that allows you to run Android games and applications. Running software this way is more demanding, but this is generally not an issue because most computers are significantly more powerful than smartphones. But a good quality Android emulator needs to do more than just allow programs to run, because using a mouse and a keyboard is very different from using a touchscreen. This is especially important for games, as they will not be enjoyable without a proper control scheme. Thankfully, Bluestacks provides this functionality; you will be able to use your keyboard instead of just clicking on the screen.
Bluestacks 5 is the newest version of the emulator, but it is unfortunately available for Windows only. Mac users are limited to Bluestacks 4, which is still a very capable emulator even though it lacks some of the newest features. The guide below will explain how to install Bluestacks on Mac to let you play smartphone games or run applications.
