Importance of installing macOS security updates

Parallels Desktop takes the best of both worlds—Mac and Windows—to provide users with the best experience in both operating systems, including your security. To keep your virtual machine (VM) safe, after installing the latest Parallels Desktop build we also strongly recommend installing all macOS security updates. Parallels Desktop depends on the security of macOS, as it runs on a Mac under control from macOS. For your convenience, you can even automate macOS updates or perform them manually.

Importance of installing Windows security updates

After installing the latest Parallels Desktop build and all macOS security updates take care of the last part, your virtual machine. Because Parallels Desktop precisely emulates Windows, the safety of your Windows VM is dependent on the safety of Windows itself. To keep Windows safe, install all Windows updates including security fixes. Check this article to learn how to update.

Parallels Desktop for Mac App Store Edition security updates

As any application installed from App Store, Parallels Desktop for Mac App Store Edition runs in a sandbox environment where all access to your data is limited. Furthermore, the App Store edition uses Apple hypervisor to run virtual machines, thus relying on the overall security of macOS. The safety of your VM while using the App Store edition depends solely on the security of macOS and Windows. As recommended above, install all security updates for macOS (including any related to the App Store application) and Windows to keep your VM safe.
