enabling MSS messaging on a mac
I’m getting “MMS Messaging needs to be enabled to send this message.
on my new MBA M1. found. How to forward SMS/MMS text messages from your iPhone to your iPad, iPod touch or Mac.
here’s what is says,
“Set up text message forwarding On your iPhone [etc[ . . . On your Mac, open Messages, choose Messages > Preferences, then click iMessage. Make sure that you're signed in to iMessage with the same Apple ID on all your devices.”
Where does that explain how to “enable” MMS messaging.. open Preference>Messages>iMessage. Then what? not place to “enable MMS Messaging.
These are many post regarding this problem. I’ve read most. It’s back to old MS solution of turning on-off. No explanation of how to enable MMS messaging
Is there no way to enable?
Thanks
