You may wonder why facebook login widget looks different when you try to log in with an MacBook. The icon is gray out and doesn’t response to your attempts to log in by this method.
It happens because Facebook login requires cookies. Unfortunately MacOS operating system, used by MacBooks, does not support them on login page window, which is making it impossible to use. We made it look look different and added some information about it just to make it sure it’s clear for your your guests.
The only way to bypass it is to use different login method like Google, LinkedIn, Twitter or simple email confirmation.
Make sure that Facebook Login isn’t the only login widget on your login page!
