After installing Emacs.app in my Application folder, I start Emacs.app from terminal by: > % /Applications/Emacs.app/Contents/MacOS/Emacs It runs like a charm, even with my full customization (includes slime, ecb, ruby & rails mode, as well as lots of other modes). But if I launch it by click the Emacs icon on the Application folder, vc-mode will be in the weird situation as I described before, no matter I load my .emacs or not. I guess this could direct us to some correct way to solve this problem. To make thing clearer, I removed my .emacs, launched Emacs.app from Application folder, and did the following tests: 1. C-x C-f ~/Code/Emacs/emacs/README It opened, with the cvs mode correctly activated. I play the vc-* commands for a while, seems everything is OK. 2. C-x C-f ~/Ruby19/src/load.c It opened, with "Loading vc-svn...done" message in the mini buffer, but all vc-* commands not working (feedback "No fileset is available here." message). 3. Running diagnosis evaluation as you instructed: M-: (executable-find "svn") says: "/usr/bin/svn" Which is NOT the correct path of my svn. In my working MacBook Pro, the SVN from Leopard installation is in /usr/bin, but the working SVN installation is in /opt/local/bin/ (from MacPorts). Here is some information about my SVNs: $ whereis svn /usr/bin/svn $ which svn /opt/local/bin/svn $ /usr/bin/svn --version svn, version 1.4.4 (r25188) compiled Sep 23 2007, 22:32:34 $ svn --version svn, version 1.5.3 (r33570) compiled Oct 11 2008, 10:20:01 Furthermore, M-: (vc-svn-registered "~/Ruby19/src/load.c") says: nil M-x list-load-path-shadows says (in mini buffer): Checking 1 files in /Applications/Emacs.app/Contents/Resources/site-lisp...

NOTE: My git is built from cloned source and installed in /usr/local/bin. $ whereis git $ which git /usr/local/bin/git And when I start Emacs.app from terminal, it gives correct path. Actually I do not know what the list-load-path-shadows exactly is, so I just list all I saw. But from all the information listed above, I guess the whole problem is something about the search path, and the key is the way Mac OS X launches GUI application from Finder (my PATH setting in .zshrc bypassed, which I consider as a common mistake, but I've never noticed). I now know how to workaround my problem, but if any suggestion or other helpful information about this issue, please let me know.
