Running DOS programs on a modern macOS system requires the use of a DOS emulator. macOS does not natively support DOS-based applications, so an emulator like DOSBox-X is necessary to create a suitable environment. This emulator allows you to run old software and games that were originally designed for the DOS operating system.

DOSBox-X is a recommended emulator for this purpose. It accurately replicates the DOS environment and supports various hardware configurations. This makes it effective for running a wide range of DOS applications and games on macOS.

Setting up DOSBox-X on macOS involves using Homebrew, a package manager for the operating system. After installing DOSBox-X, you can download and run your desired DOS programs directly within the emulator. This method enables you to use legacy software on a modern system with minimal setup.

Steps to run DOS progam in macOS using DOSBox-X:

  1. Open the Terminal on your macOS.
  2. Install Homebrew if it's not already installed.
    $ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  3. Use Homebrew to install DOSBox-X on your system.
    $ brew install dosbox-x
    Warning: Treating dosbox-x as a formula. For the cask, use homebrew/cask/dosbox-x
