When I heard about Yosemite back at WWDC, I was overjoyed and then devastated. At first, I was thrilled about Continuity, which would allow my iPhone, iPad, and Mac to work more closely together. I was devastated to find out, however, that Continuity requires Bluetooth Low Energy, which my Mac is too old to have.

Then I saw this tweet:

@tapbot_paul @iconmaster Handoff/Tethering/AirDrop: proximity (BTLE) SMS: both on active network Phone: same network (WLAN, LAN)

I cannot effectively describe how excited this made me.

Here’s how you turn on “SMS Relay” with iOS 8.1 and Yosemite:

1. On your iPhone, Settings > Messages > Text Message Forwarding
2. On your Mac, open Messages
3. Back on your iPhone, turn on the Mac you wish to enable
4. Wait a few seconds for the confirmation message to show up (shown to the right)
5. Enter the code on your iPhone

I tried it immediately after enabling it, and it worked no problem.
