X-Forwarding instructions for Mac OSX This page describes the process of using X forwarding to run a Linux X11 application remotely from a Mac. X forwarding is the process of connecting to a remote Linux system and launching a program from that system, but having the window display on your local system. Think of it like launching a program from a Citrix server and using it locally. Downloading the Xquartz application Apple used to provide an X11 app with the default installation of Mac OS X.

However, since the release of OS X 10.8 Mountain Lion, Apple dropped this app from the system. There is a third-party application that you will to make use of X forwarding called 'Xquartz'. Installing Xquartz The Xquartz installer is a macOS 'pkg' bundle contained within a disk image (DMG) file. Double-click on the '.pkg' file to start the installation.

If you need to do this, just replace the -Y flag with -X when connecting, like this: $ ssh -X netid@hostname.illinois.edu NOTE: Replace 'netid' with your username and 'hostname' with the system you want to login to.

Poor performance X forwarding is a very laggy and slow process. However, it seems to be even worse while using Xquartz. A more performant solution would be to use FastX instead if it is available on the system that you are connecting to.
