Just updated my MacBook Pro to 10.9 without issue. I also have a Mac mini on my network, still running 10.8. It's name on the network is macmini.local. If I try to use AFP to connect from the MacBook to the mini with afp://macmini.local, I get "There was a problem connecting to the server...." I then enabled Samba sharing on the Mac mini, and connected with smb://macmini.local successfully. I know that SMB is meant to replace AFP in Mavericks. Does this mean that AFP connections simply won't work from a Mavericks machine anymore? Or is this just a bug?
