Today Apple announced a new feature on the next Mac OS that works only with Macs and iPhones but I have been doing for a long time with any cell phone and any computer.
Here are the simple steps to do the same thing. All you need is a US cell phone number, Google Voice (free), the Google Chrome browser and Hangouts for Chrome.
1. Get a free Google Voice account and link it to your cell phone number.
2. Install the Hangouts plugin for Chrome.
3. Configure Google voice to ring your Hangouts account.
Now, any time someone calls your phone, you can answer it from your computer. True, you have to be running your browser, but you are most likely running it anyway, so not really an extra effort. Plus, you are not limited to only using a Mac and an iPhone. It works combining any device pairs. Mac computer or iPad ir iPhone or Android or BlackBerry. The phine device doesn't matter, nor does the computer.
In fact, you can combine multiple devices not only two.
So, there you have it. How to do it without waiting for the next Mac OS release or even needing a Mac at all.
Don't get me wrong, Macs are my computers of choice, but I am also realistic. Not the only hardware to do magical things with. I have a Galaxy S4 and an iPhone but the phone device is irrelevant.
Enjoy the tip.
