All macOS Apple desktop systems have Apple Screen Sharing enabled which allows you to remotely access a Apple desktop system environment.
Open a ssh tunnel via the ssh gateway on port 5900 before you can connect to the systems. This no longer work through the Physics VPN.
If you wish to open a ssh tunnel to use Screen Sharing on your Apple desktop system do the following:
Set up the SSH gateway into the Physics department following the instructions here

In the Terminal window enter the following command replacing username and computername with your physics account name and the name of your computer: ssh -L 59000:localhost:5900 username@computername.nat.physics.ox.ac.uk
You will then be prompted for your physics username and password twice, once for the ssh gateway and once for your desktop.
Once the tunnel is open keep open the Terminal window until you have finished your session.
Now follow the instructions to connect to the system from the instructions for your operating system however replace the name of your computer with localhost:59000 e.g. vnc://localhost:59000
