On the remote computer, go into System Preferences > Sharing and check the boxes to allow remote login and remote management

Find the remote computer’s hostname


This will be something like xxxx-55-555-55-5.university.edu. On the local computer, run

ssh hostname

And enter the admin password when prompted. Or, to access a single account,

ssh username@hostname

Change the remote hostname

I could not get this working on macOS. I found one related StackExchange thread, but there is no working solution yet
