I have using the beta version of OS X Yosemite on a MacBook Pro 13 inch. So far, the end user experience is good. Here is the list of reasons why you’ll find OS X Yosemite better than Mavericks.
OS X Yosemite is designed by Johnny Ive. It uses same designs elements as iOS. The translucent Windows look great. Everything is still neat and friendly. The dock is looks much better and all the icons are redesigned. It’s new and familiar at the same time.
Notification center is in Yosemite is very much similar that of iOS 8. It allows you add widgets to it which is really great. It’s comes really handy to check your notifications without switching the app you are working on.
You can’t imagine a Mac without spotlight. Its the easiest way to search anything on your Mac. In Yosemite it’s even better. Just press command and space and spotlight search window will come on the screen type anything and it will not only search locally stored files but also internet. For example if you search for Sachin Tendulkar you’ll get all the flies and other stuff which has anything related to Sachin along with snippet of Wikipedia article. It’s awesome.
The new iMessage app in Yosemite will now have normal SMSs for your friends which ensures that you never miss anything from your friends.
OS X Yosemite allows you to answer your iPhone calls on your Mac. You can even dial a number through your Mac using cellular services of your iPhone.
