I've done everything to set up my iPhone 6 Plus and my 2014 Mac Mini, both running the latest version of their respective operating systems, to enable handoff and SMS messaging as described and detailed in the article at http://www.igeeksblog.com/setup-handoff-on-mac-os-x-yosemite-and-iphone-ipad-on-ios-8 - I do know that I have to have the phone on, which it is, in order to send SMS messages. I have two unsolvable problems:
1. Although Bluetooth is on for both devices, the phone doesn't see the Mac.
2. Although both devices show they are logged in to iCloud, and the Mac is connected to my local Wi-Fi network, I do not see an iCloud account in Messages, Preferences, Accounts tab. Only my regular Messages account, and a Bon Jour account, which is disabled, appear in the accounts list, and it is not possible to add the iCloud account. I can add an account, but it has to be either a Yahoo, AIM, Google Talk, or other unspecified account type.
Oh yes, since my Applecare free phone support expired last July, calling them is not an option, so here I am.
What have I not done, or what can I check on what device to get SMS text messaging enabled on the Mac Mini?
