After logging on, I see this dialog box pop up. Whenever I dismiss it, it reappears 30 seconds later. (Stealing focus at the same time! Grrrr!)

There was a problem connecting to the server "Slate".

"Slate" is my old iMac, which is sitting on the desk next to me, turned off. How can I stop my new Mac from constantly trying to connect to my old one? Both are running 10.7.1.

Did you set up a shortcut to automatically mount the drive? Looking in System Preferences > Users and Groups > Login Items. Or, is there an application/document that's automatically loaded on launch that points to the iMac? –  canderson Sep 21 '11 at 23:31
@ChrisAnderson: No, nothing that I can see. Is there any way to detect which application is responsible for connecting? –  Brant Bobby Sep 21 '11 at 23:39
Nothing specific that I know of. I'd just check the Console if you haven't already, possibly you can find the error there. –  canderson Sep 21 '11 at 23:42

Check System Preferences>Accounts>Login Items to see if there is a disk that is supposed to mount when you login. Make sure you check all of the user accounts.

I'm pretty sure this was happening because when I logged out, I was running an app which was located on the other computer.

I logged off and unchecked the "Reopen windows when logging back in" box, which stopped Lion from trying to reopen the app the next time I logged in.

Good answer. But one pro tip: If something like this happens again, use lsof from Terminal. That is a Unix tool to show you the list of open processes. And if you run it like this sudo lsof | grep Slate the output of lsof gets filtered through grep and you could then see exactly what application/process. Is attempting to use Slate. –  JakeGould Oct 10 at 2:38

I suspect you are connecting to a legacy file server as described in the kbase article below.


We saw similar pop ups but clearing up our mounts addressed the issue.

I had exactly the same problem, with my new Macbook continuously attempting to reconnect with my old Macbook which I had at one time connected to through the same wifi network. A similar alert would appear on my screen once every few minutes or so. I followed the above directions as far as "Looking in System Preferences > Users and Groups > Login Items."

Then I clicked the lock icon in the bottom left corner of the window and entered my password to enable changes.

I then clicked on the Guest User icon which appeared directly under my Admin Icon.

In the new window I clicked to disable "Allow guests to connect to shared folders."

I closed the lock and since have not had the issue.

Hi welcome to AskDifferent, I find if a question is worth answering it is worth upvoting. As you can see the person asking the question has already answered it and accepted it, hence the edit. Please take the time to read the Answer and Question section of the help page. –  Deesbek Jan 29 at 3:06

I managed to eliminate it by adding a folder from the named server to the "login items" and then deleting it. Weird, but it worked for me. Hope it helps.

I had this problem as well; at login my Mac (iMac running 10.7) was trying to connect to an old Windows Home Server that I have removed. I found that there was a .../Login Items entry that was trying to mount a volume from that old server. Deleting that entry solved the problem.

Thanks for the tip.

I found a similar issue with teacher computers trying to connect to an obsolete server. I found the auto-connect file(s) in MacintoshHD/Users/Shared. Then I deleted them. Problem gone!

But how did you find the auto-connect files, Marie? –  Dave Nov 3 at 21:59
