OSX Lion To Lion File Sharing Not Working – How To Fix It

After upgrading both my Macs to Lion on Wednesday, I discovered this morning that I can no longer mount shared folders between them. I tried going in both directions, and both failed with a very non-intuitive “Connection failed” message. I went to Preferences, Sharing, File Sharing and tried turning it off and on again, but to no avail. I then tried googling for the problem and saw lots of people with the same situation, but this one guy hit upon the “solution” to get it going. You have to turn off AFP sharing, and just leave Windows sharing on. Here’s the original answer. To summarize:

  1. Go to Preferences
  2. Click on Sharing
  3. Click on File Sharing on the left-hand side
  4. Click the Options button
  5. Uncheck “Share files and folders using AFP”
  6. Check “Share files and folders using SMB (Windows)”
  7. Click the Done button.

At this point, you should be able to connect from the other machine. If you need to go in the other direction, perform these same steps on the other machine.

Steve, please get this fixed ASAP, OK?
