NoMachine, available for Mac, Windows, Linux and ARM, is a remote desktop software, designed for anyone who wants to access a single or multiple computers using one simple tool. It ensures secure and reliable remote desktop connections, regardless of what network you are connecting from, lets you stream multi-media content, edit documents, print and transfer files and more. Installed on the computer you want to access, NoMachine Free Edition permits one connection to let you get access to the physical desktop (including a the desktop of a virtual machine) from remote. Instead, if you require multiple connections to the same desktop, NoMachine Enterprise Desktop is what you need.

NoMachine can also be used to share your desktop on-the-fly. For example, you can let another user connect to your desktop whilst you're working on it so that you can collaborate together. Work on a document together, share your screen whilst watching a film, swap files or simply receive help with troubleshooting a problem.

To access an unattended remote desktop using NoMachine, a user account is required on the remote computer you want to connect to. Alternatively, for attended desktop scenarios you can connect as a guest using Guest Desktop Sharing.
