Sim tool on MacOS not accepting menu input

Trying to enable GloNet to give some resources on an idle computer. I’ve got the client installed (and up to date) on my iMac. I launch the program, get the menu to pop up, but I’m unable to select any of the items. I see options 1-5, but I’m typing 1-5 doesn’t select an option as expected. Hitting return simply exits the program. Am I doing something stupid, or is this an issue? Cheers.

Typing the number doesn’t work. You’ll have to use the arrow keys to select it, then hit enter.

Well don’t I feel stupid! Thanks so much for the helpful reply!
