When I try to text on Mac, and I hit the return button to send it, it will highlight the message instead of sending it (as if I wanted to copy the message). Does anybody know how to help with this?
That is a strange, because pressing the return button in Messages on macOS 10.14.6 sends the message as you expected it to do.
Are you using the return key on a numeric keypad? That might be the reason?
The other option is to press
return which should send the message. Other than that, you can try signing in and out of Messages app on the Mac, and ensure message forwarding is enabled in the iPhone's messaging settings. I'll keep you posted if I find out any other setting to change it.
I just found that you can potentially make the
return key act as send message by creating an app specific shortcut in Keyboard Settings. I'm not 100% sure it will work but give it a try?
App Shortcuts then add a new shortcut and select the Messages App from the Application Dropdown menu. Enter the exact menu command name
Send Message. Now in the keyboard shortcut box it won't let you just press the
return key, so you will need to press
return but it should display just
return in the box.
Now go back to the Messages app and see if it will require you to press the
fn key before pressing
return or without the
fn key? If not you can just remove that app shortcut from the keyboard settings.
I've attached an image what the shortcut setting looks like.
