Alfred Extension: Remove Download Warning

“This App.app” is an application downloaded from the Internet. Are you sure you want to open it?

This warning is very common to most of us. It saves non-tech users from (hopefully) installing malware on their computer. Most of the readers here however are tech-savvy enough to make a conscious decision whether, in this case, an app, is always allowed to be launched without asking.1

Alfred Powerpack to the rescue!

This is a Shell Script Extension which integrates itself as Action and will execute the following command. It will remove the quarantine extended attribute from an app/folder2 or a single file:

xattr -d -r com.apple.quarantine {query}



Call Alfred, press fn (or whatever key you set to bring up the actions), type “Remove” and press ↩.



Want a shiny icon to accompany this extension? Here’s a ready-packaged download for you:


  1. You can disable the warning globally as well. I don’t want to do that, I think the warning itself is good, but I want to be able to disable it on a case-by-base basis. 

  2. and all of its subfiles!
