new player — early technical problem

Hello everyone. I look forward to reading things all over this forum to deepen my understanding of IF.

I’m using the newest Inform 7 on my Mac, and all I have typed in for the Source is:

The bedroom is a room. “Your sister’s bedroom.”
The bathroom is a room. “Just an ordinary bathroom.”
The bedroom is east of the bathroom.

I theoretically understand how to do more complex things, but this is how I’m starting out. (It’s like my third day trying this all out.) But when I press Play after this is all typed in, nothing appears on the Story side. Nothing at all — I can’t type anything or look at anything. What am I doing wrong? Thanks! : )

If you’re using Sierra, you’re probably running into the bug described in this thread.
