Easy peasy on my Mac!
Super useful app for finding out the IP addresses for all devices on your network: Fing (that’s the Android store link but I think it’s also available for other OS)
On Mac, open Terminal.
$ ssh -X pi@<add IP address here>
It will ask you to type in your password, which by default is ‘raspberry’.
In addition to you being able to control your Pi via the Terminal on your Mac, this will allow you to open Pi applications in a window on your Mac screen.
E.g. I can open the program Geany in a window on my Mac just by typing
$ geany into the Terminal
