The wifi suggestion might be the problem. We did update our router recently and I know they used to see each other. Oy. How do I fix that? I usually defer hardware problems to Waitin4CJ and he's not here right now. I'm more comfortable troubleshooting software.
Update: I went to System Prefs and set both machines to the 5G network (one was on 2.4G) but it's still not showing up.
I think I only have one user ID but I'll verify that next.
Update: Yeah, just one user ID. Both on the cloud. I don't know what the problem is. It doesn't show in the Finder sidebar either. Now what?
