+ +Q41. File associations are broken in Mac OSX. Clicking on a dot file doesn't open Graphviz. +
+The immediate fix is to rebuild the Launch Services database like this: +
+1. Trash all other versions of Graphviz.app on your system, except for the just installed one. You can use either of these command lines to find it: +
+
locate Graphviz.app
+
+or +
+
find / -name "Graphviz.app"
+
+2. Run the following command line: +
+
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r /
+
+or +
+
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r /Applications
+
+which deletes the Launch Services database and rebuilds it from existing apps. You may need to sudo to do this. +
+3. Verify that the Graphviz.app can now open .dot files and Microsoft Word can still open its own .dot files. +
+One artifact of this will be that Microsoft .dot files may appear with the Graphviz document icon. Unfortunately there doesn't seem any a priori way of getting the system to determine whether an arbitrary .dot file belongs to Word or Graphviz -- you can choose which application to open with by right-clicking or control-clicking on the document icon and choosing the app. +
+As for why the Launch Services database doesn't automatically register Graphviz, +we're not entirely sure but suspect this only happens if both conditions +hold true: +
+A. The user had installed Microsoft Word.
+B. There is also another version of Graphviz.app present in the system. (Possibly the previous version 1.13 released by Pixelglow Software)
