I’ve been getting a warning dialog on my Mac (Lion 10.7) when opening Adium. It recently updated to the newest beta and is presenting the following quarantine message every time I open it –
“Adium.app” is an application downloaded from the Internet. Are you sure you want to open it?
Every other time I have gotten the quarantine message, it clears itself after the first launch. This time it did not. I found a quick and easy way to remove the quarantine extended file attribute:
sudo xattr -d -r com.apple.quarantine /Applications/Adium.app
Relaunch Adium one more time with the “first time you’ve opened” warning and you’re set!
