I get this error when I try to launch Sublime Text or SourceTree from tmux:
$ subl
Unable to launch Sublime Text 2
$ stree
Unable to open SourceTree
It seems that I can't open os x apps either:
$ open MPlayerX.app
LSOpenURLsWithRole() failed with error -10810 for the file /Applications/MPlayerX.app.
I'm using Yosemite OS X 10.10 (14A388a), iTerm 2 with zsh, tmux 1.0a. Had the same problem using bash. Any idea what's going on?
