Hello! I have an iPhone 5s on iOS8 and a 2013 MBAir on Yosemite. Bluetooth is turned on on both They're both on the same wifi network They're both logged in to the same iCloud account The "Handoff" and "iPhone cellular calls" buttons are both on on the phone The "Allow Handoff" button in settings and the "iPhone cellular calls" button in FaceTime is on on the computer I've tried Logging into and out of iCloud and restarting both devices Turning bluetooth on and off Testing bluetooth by sending files back and forth among other things When I send SMS texts from my iPhone they don't show up on the Mac, and I can't send SMS from the messages app on the mac Also, weird things are happening. After the iOS8 update, I've noticed a few times when I'd been sending iMessages from the Mac, and when I go to my iPhone they show up as being sent as SMS. How does that make any sense? I've also sent iMessages from my iPhone, then they don't show up at all on Messages on the Mac. The received iMessages show up, but not the ones I'd sent. I've had some texts show up on the phone as being sent as SMS, then on the Mac it says they were sent as an iMessage. When I get a call on my phone, it'll show up on my Mac and it'll ring, but it bugs out whenever I try to answer it so it's never successfully worked. Same thing happens when I try to start a phone call from the Mac My phone's network used to show up as an option to connect in the Mac's wifi menu, but recently since I've been messing with things I haven't seen it show up anymore. When it did show up it could never connect, though. I've never seen the little "bouncing icon" or the other handoff icons on either device. I don't know what else could be wrong or what else I could do to try to diagnose/resolve this. I'm turning to you, fellow Apple nerds. Any help would be greatly appreciated.
