Ultimate Guide to Running Windows on Mac Using Parallels Desktop

Macs are known for their sleek design, stability, and performance. However, there are times when Mac users need Windows to access certain apps, software, or games that are unavailable on macOS. This is where Parallels Desktop comes in.

Parallels Desktop allows you to run Windows and macOS side by side without rebooting your computer. Unlike Boot Camp, which requires restarting your Mac to switch operating systems, Parallels runs both simultaneously. This guide will help beginners set up Windows on Mac and get the most out of Parallels Desktop.

What is Parallels Desktop and How Does It Work?

Parallels Desktop is a virtualisation software. Virtualisation allows one computer (your Mac) to run another operating system (Windows) inside a virtual environment. Think of it as a computer within a computer.

Key Features:

• Run Windows apps alongside Mac apps seamlessly

• Multiple view modes: Window Mode, Coherence Mode, and Full Screen

• Drag-and-drop file sharing between Mac and Windows

• Snapshots for easy backup and recovery

• Automatic Windows updates and integration

Parallels is especially popular among developers, students, gamers, and professionals who need Windows-only software without switching devices.

Check System Requirements

Before installing Parallels, ensure your Mac meets the following:

Minimum Requirements:

• macOS 13 or later (Ventura, Sonoma)

• Intel or Apple Silicon (M1/M2) Mac

• 8GB RAM (16GB recommended)

• 20GB free disk space for Windows

• Internet connection for downloads

Recommended:

• External monitor support if you plan multi-screen usage

• Backup of macOS files before installation

Checking system requirements ensures Parallels Desktop runs smoothly and prevents crashes or lag.
