All you need to know about Parallels Tools installation in Parallels Desktop for Mac

Parallels Support team guest authorsDineshraj Yuvaraj

When you set up your first virtual machine in Parallels Desktop for Mac, you may have noticed Parallels Tools installing automatically (in the guest operating system). So what is Parallels Tools and why is it that important for Windows/Linux/Mac VMs in Parallels Desktop? Why is it installing automatically? How do I know if it’s installed or not? In this blog, I will answer these questions and more. Read on!

What is Parallels Tools?

Parallels Tools is a set of drivers for the guest OS that is installed in your VM. It helps you use your virtual environments in the most comfortable and efficient way.

You can move the mouse seamlessly between the VM and your Mac, change the VM’s screen resolution simply by resizing its window, synchronize your VM’s time and date settings with the host OS, share your Mac disks and folders with its VMs, and copy text and drag and drop objects from Mac OS to a VM and vice versa. Visit this page of the User Guide to review all the features managed by Parallels Tools.

What if Parallels Tools is not installed?

Although you technically can run the guest OS without Parallels Tools, you will lose important functionality targeted primarily at two-OS integration.

How do I know if Parallels Tools is installed?

With Parallels Tools installed, you can move the cursor between the virtual machine and Mac; the mouse and keyboard are released automatically. One of the easy ways to detect that Parallels Tools is not installed is to start your VM and look at the status bar of its window. If the tip “Press Ctrl + Alt to release the mouse and keyboard” appears in the status bar of the VM’s window, this means that Parallels Tools is not currently installed.

Parallels Tools location on Mac

While you likely won’t need to locate the Parallels Tools image for Windows VMs manually, you might need to know the location for Linux and Mac OS images, as you need to mount them if automatic installation did not work for some reason. Here is how these images appear:

prl-tools-win.iso – Image for Parallels Tools for Windows guest operating systems

prl-tools-lin.iso – Image for Parallels Tools for Linux guest operating systems

prl-tools-mac.iso – Image for Parallels Tools for Mac OS X

These images can be found in the following location on your Mac:
