Are you certain about SMS messages appearing on a desktop (no cellular service) Mac? I have yet to see them on any iMac or non-cellular iPad.
Absolutely positive! I just deleted half a hundred texts from different candidates wanting money.
A late reply to this post, but SMS messages, that is messages to a non-iPhone, only appear on a desktop Mac if Text Message Forwarding is turned On in the iPhone in Settings>Messages. If you have more than one Mac, in this setting you can select which Macs get the forwarded SMS messages.
