Safari only: "SecurityError (DOM Exception 18): The operation is insecure."

On Meteor 1.4.0.1
Any ideas why I’d get the following area on Safari only on macbook? Chrome and FFox work without issue…
I’ve read about cookies on IOS, but that fix didn’t work on macbook.

“SecurityError (DOM Exception 18): The operation is insecure.”

Maybe try updating your boilerplate-generator package?

meteor update boilerplate-generator
