Your Processing applet is damaged and can’t be opened. You should move it to the trash.

Your friend just spent the better part of a weekend making an applet for you to do some crazy awesome kickass thing but every time you try to open it, you get this error message “The .app is damaged and can’t be opened. You should move it to the trash.

Uh Oh.

Bah! But it worked fine on her computer! In fact, she even emailed it to herself, downloaded it, and reran it without any problem!

Fret not! Salvation is near! You know it’s true because I’m overusing exclamation marks! (!)

Here’s how to fix it (on a Mac):

  1. Go to System Preferences
  2. Click on Security & Privacy
  3. Change your Gatekeeping settings to “Allow applications downloaded from *ANYWHERE*”.

System Prefs --> Security --> Allow applications downloaded from *ANYWHERE*[Click for a larger image]

There. It should work now.

And if it doesn’t, I guess you’re S.O.L….
