Chosen Solution
I’ve tried to understand the differences between Messages and iMessage on my desktop Mac. I really feels like Apple is avoiding a straight answer, they move the question to an iOS answer. I have no problem with Messages with Apple users on iPhones or iPads, but been unable to understand the gobbledygook that Apple is trying to feed me on trying to message with android users. Sorry Apple, not all users have the brilliance to use your products. Seems like Apple is trying to baffle me with bull sh*t. Blue icon with Messages but Green icon with iMessages (but it only seems to be my iPad.) Anybody doing this successfully?
If you open your Messages settings under the Settings Gear icon within your iPhone or iPad that has cellular service, slide down to the Text Forwarding section to then enable your Mac device to accept both. For some reason Apple won’t allow SMS messages over TCP/IP yet allow iMessages to use it. Now your iPhone or iPad will forward to your Mac the SMS messages.
