Introduction
Parallels Desktop is a popular virtualization software that allows you to run other operating systems, such as Windows, Linux, or macOS, on your Mac. It is a powerful and feature-rich application, but it can be expensive, especially if you are looking for the Pro version. That is why we are going to explore some free alternatives to Parallels, so you can run multiple operating systems without breaking the bank.
What are Virtual Machines?
Before we dive into the free alternatives, let’s first understand what virtual machines are and why they are so useful. A virtual machine (VM) is a software-based emulation of a physical computer system. It creates a virtual environment on your host machine, allowing you to run a different operating system alongside your primary operating system.
Think of it like this: imagine you have a physical computer and you want to run a different operating system on it. You could install that operating system directly on your physical computer, but this would require you to restart your computer every time you want to switch between operating systems.
With a VM, you can install a separate operating system within your existing operating system. This means you can run both operating systems simultaneously, switching between them whenever you need to.
This has many benefits. For example:
- You can test out different operating systems without affecting your main operating system. This is a great way to try out a new OS before committing to installing it on your computer.
- You can run programs that are not compatible with your main operating system. For example, if you have a Mac and need to run a program that only works on Windows, you can install Windows in a VM and run the program from there.
- You can create a safe and isolated environment for testing software or running applications that might be insecure. This is particularly important for developers or security professionals who need to test software in a controlled environment.
Why Use a Free Alternative to Parallels?
There are many reasons why people choose to use a free alternative to Parallels.
- Cost: Parallels can be expensive. For the Pro version, you may have to pay up to $100 per year. If you're on a budget, using a free alternative will save you money.
- Features: Some people find that they don't need all of the features that Parallels offers. Free alternatives often provide the essential functionality you need without unnecessary bells and whistles.
- Flexibility: Some people prefer the flexibility of using a free alternative. Free alternatives are often open-source, which means you can customize them to your liking.
