PlayOnMac is a free compatibility layer and emulator for macOS that allows installation and usage of video games and other software initially designed to run exclusively on Microsoft Windows.

PlayOnMac is based on the open-source Wine project and therefore creates and uses virtual drives much like Wineskin wrappers (the virtual drives are essentially Wineskin wrappers operating on a particular version of Wine).

[1][2] Furthermore, it uses an online database of installers (called scripts) that are applied to different applications that need special configuration.

[3][4] Therefore, PlayOnMac allows users to install some of the most popular Windows programs and many video games as well.

Lastly, PlayOnMac has been developed using a combination of two programming languages, more specifically Bash and Python.
