I just upgraded to Mac OS X Yosemite 10.10 and Alfred 2 fails to launch.

In Activity Monitor, it reports that it is not responding, and the only thing I can do is Force Quit it.

Console doesn't report any messages except the kill message from my force quit.

Any advice would be appreciated.


Don't use Alfred myself so I can't give a specific answer.

Something I would try though is using opensnoop to see if I can work out where it is failing.

If you type sudo opensnoop | grep alfred into a Terminal it'll show you all the files that Alfred is touching. That might help you identify where it is crashing, for example if it is a corrupt plist file.

  • All that opensnoop reported was the following 502 1059 BetterTouchTool 30 /opt/homebrew-cask/Caskroom/alfred/2.3_264/Alfred 2.app/Contents/PkgInfo

  • That is weird. I just installed Alfred through brew cask install alfred, ran it a couple of times, then launched it again with sudo opensnoop | grep alfred and it spit out all kinds of stuff. Maybe check your brew installation with brew update && brew doctor, you'll get a warning about Xcode being out of date as Apple haven't posted 6.1 to the App Store yet, but it may throw up other more specific errors.

  • I may just brew cask uninstall alfred then brew cask install alfred and see what happens. It's 3am for me and I'm pooped...so it will have to wait till the morning (or more accurately, a little later in the morning).

  • Or just be patient!!! I guess that since Alfred hooks into search results indexed by Spotlight and Spotlight was indexing 12Tb of HD, it was slowing things down. Alfred is working now.

  • I uprooted your answer because, although it didn't solve my issue, the opensnoop cli app was a nice discovery for me, and can come in handy when I have other problems. Thank you.
