Send as SMS on Messages for OSX
Is there any way to 'Send as SMS' from messages for Mac as there is on iPhone? I have a number of contacts that messages detects as iMessage but is unable to send. A popup advises that the recipient is not set up for iMessage, but no option is given to send as an SMS, resulting is me having to do it from my phone.
