I was also unable to click anything on the GUI when running Eddie on my Apple M1. I did find a fix though..
Click on the Eddie icon in the menu bar and select Show Main Window. This should allow you to enter your user name and password. You may need to tab and enter instead of mouse clicks to save your settings.. Once connected, set your app preferences to remember settings and to reconnect on startup so you don't have to go through it again.
Although it works, it definitely doesn't like to play with with the M1 so this needs to bee looked at.
