Apple is trying to bring the mac and iOS experience together and today they have introduced few changes to notification centre in OS X Yosemite. The new Notification Centre now features a Today view like iOS showing your calendar, stocks, weather and other info. But Apple has gone a step ahead and has now allowed widgets too in the Notification Centre like calculator for easy one click access to all the important tasks.
Apple has also allowed third party apps to integrate their widgets in notification centre which will enhance the usability of the Notification Centre. Other than the new notification Centre we also get a new redesigned Spotlight Search. When you click on the spot light search you will get a translucent search bar in the middle where you will not only be able to search for your files or mails but much more than that. When you type anything in spotlight search it will show results from wikipedia along with other useful sources which might be of your interest.
You will now be able to search for your favourite movie and the search will let you know about the movie theaters showing the movie or the streaming media in itunes. The Spotlight Search is much more productive now which will change the way you search!
