Easily fix problem with Facetime log in

Recent­ly, Face­time on my work lap­top stopped work­ing prop­er­ly. Even with the cor­rect ID and pass­word, the app would “ver­i­fy” my account but then refuse to acti­vate Face­time. Instead I would get this error:

The reg­is­ter­ing device does not have appro­pri­ate credentials

Thanks to this post:

I learned that a sim­ple “kil­lall ima­gent” com­mand in the ter­mi­nal would restore Face­time functionality!

Yay, inter­net.
