I have the macOS Sierra final beta, but I seem to be unable to send or receive the new iMessage effects.
Such as the Invisible Ink:
Is it possible to view these effects on macOS Sierra currently? And if it is, how can I enable it?

There is a mySIMBL plugin I helped write that allows you to send messages with all the effects.
You won't be able to see them on your Mac but if you send it to a device on iOS they will.
