Mathematica can be run remotely on a university computer using the UI Virtual desktop. See here for instructions.

You have to download a plug-in. (The instructions for Macintosh seem to be out of date; you should get a plug-in for Mac here; choose "Citrix Clients" and then "Citrix Online Plug-in for Mac - Version 11.0".)

Once you are equipped with a plug-in, access the virtual desktop here.
