Apple unveils OS X Yosemite, iOS 8 with HealthKit and home automation

 OS X 10.10 Yosemite
In recent years, the success of iOS has led to the cross-pollination of some features to the Mac. Notification Center, Launchpad’s grid-like app pages, and Mac App Store are some features that Apple borrowed from iOS and injected into OS X.
However, now that Jony Ive is in charge of leading software too, things are changing. OS X Yosemite, the next version of the Mac’s operating system, incorporates design elements from iOS. The graphical user interface has been flattened. There’s greater use of translucency, much like iOS 7. (A "dark" theme is also available as well.)
iOS 8 & Health
iOS 7 upset a lot of people. Users complained about everything. The colors were too bright. The icons were too flat. The 3D parallax motion effect and zooming icons were making people nauseous. The list goes on.
The OS lacked serious polish. Even today, there are tons of little complaints and bugs that haven’t been fixed. ;iOS 8 isn’t a complete OS revamp. iOS 7 already did that. Consider it a heavy dosage of polishing and tweaking.
At last, iOS 8 has interactive notifications. For instance, if you get a notification on the lockscreen, you can swipe and then respond to it. Or if you get, say, a message notification on your screen, you can swipe down on it and then start responding. No need to go to the app anymore.
Smart Home Automation
As we’ve said before, there are tons of Internet-connected smart appliances. The problem is, there isn’t any kind of link between them. Apple didn’t talk much about it, but it aims for the iPhone and iPad to become the "common network protocol."
HomeKit will connect locks, cameras, doors, thermostats, plugs and switches and more. It’ll have secure pairing, allow individual devices to control third-party products and Siri integration.
