Sierra - Alfred hangs when opening (other) app for first time


Recommended Posts

Hi there


Alfred v3.2.1[768] currently hangs on Sierra 10.12.2 (Macbook Pro 2016) when opening an App for the first time.


What is happening is Mac's "are you sure you want to open this app, you just downloaded it from the internet" () appears behind Alfred, with the window focus, freezing the Alfred window.


Steps to repeat:

1) Download an app like Bartender, Skitch etc from the web

2) Move the app to Application folder, give Alfred about 2 sec to index it

3) Try to open the new Application with Alfred (i.e. CMD-Space, type "Bartender", press Enter)

4) Alfred freezes

Upon killing Alfred with Activity Monitor, you'll see a screen like below appearing behind Alfred



Previously, on El Capitan, I think Alfred moved the modal screen in front of Alfred, and dismissed the Alfred bar itself.


Let me know if further info is required.

@snowfox Alfred 3 launches apps off the main thread to work around this issue. I've just re-downloaded Google Chrome to test, Alfred disappears then you get the popup asking if you want to open it.


  • Are you seeing this with all apps you have downloaded?
  • Also, the screenshot you posted is slightly different as it looks like you are trying to launch an app directly from a dmg instead of moving to /Applications... could this be contributing to the issue?

If I can reproduce this, I should be able to fix it!
