Apple has announced four major updates for MacOS at WWDC 2016

Continuity, Siri, a new name.
It’s all about the latest version of Apple’s desktop OS. Apple’s WWDC 2016 conference took place last night, where Apple introduced a number of new optimizations and features for MacOS, the highlight of which is the need to change the name from OS X to macOS. Officially renamed macOS Sierra, the 16-year-old operating system is being renamed to align all Apple operating systems and give them a more integrated naming scheme with iOS 10 and other operating systems. Of course, it doesn’t add much functionality to your life with a Macintosh, but Apple did want to make the big announcement before announcing that it would make a difference.
Continuity and inter-device communication
Keeping up with the naming of the operating system, Apple wants its devices to work in tandem with each other, and on that note, offers better inter-device communication. Continuity of features begins with unlocking a macOS device with an iPhone or Apple Watch. You can now authenticate your iPhone or Apple Watch with your MacBook or iMac and say goodbye to long, complicated passwords. It is hoped that this will save time and energy on the right combination of letters and numbers and provide an easy way to log in to a macOS device.
Another problem that Apple wants to solve is inter-device data transfer. For example, if you create an instant note from a conference call and want to instantly transfer it to your mobile device, you can now choose to copy and paste text, video, photos and links to another Apple device, thanks to Universal Keyboard. Previously, email was the only way to do this, and Universal Keyboard is now here to facilitate continuity and make use more seamless. You also get remote access to your Mac from other registered Macs and even from your iPhone and Apple Watch.
Stitching together essential, shared features is part of a continuum that will continue to grow in the future, beyond macOS.
Siri on the big screen
Apple’s arguably popular voice assistant, Siri, has finally made its way to MacOS. Introduced to the iPhone 4s with iOS 5, Siri has been integrated into watchOS and tvOS since its inception. Naturally, it was time to merge Siri into Makos. Quickly available at the top-right or with a tap on a button on the dock, Siri introduced herself to a hall of technology reporters at WWDC 2016 who politely acknowledged her presence with small applause and a heartfelt, eyebrow-raising smile when Siri said, “There are no complaints about the lack of Windows here”.
Apple has now targeted Microsoft and Cortana, introducing specific time-based and keyword-based searches, including keyword tags. You can also ask Siri to play music from your local music or iTunes collection, search and pin queries in the notification panel, pin photos directly to a document (Cortana only provides links to photos to pin in the document) and even send direct messages via voice. Can. Order Of course, these were all part of a stage demo and the real-life implementation remains to be seen. On paper, at least, Apple has given Siri a big boost over Cortana by introducing voice-powered functionality, which Microsoft could have achieved earlier, but missed.
iCloud optimization
macOS brings Sierra optimized storage, which clears files that will never be used again to free up space, such as Safari web cache, inactive downloads, copies of old documents, and previously read emails. It comes with more optimized iCloud storage, which automatically backs up your old slides, sheets, movies and other unused files to 150GB of free storage. It will be easier for you to access iCloud files with more optimized drives ready for access on any Apple device.
Other incremental upgrades
macOS Sierra brings picture-in-picture videos to desktops, so you can keep an eye on games or music videos and keep working on your email or word document. You’ll also find tabs across every macOS app, without the need for developer involvement because the feature is deeply integrated into the OS. MacOS brings Apple Pay to the desktop operating system with mobile verification with Apple Touch ID, but since it will not enter India for the time being, it will have very few consequences, at least for a day.
