I know, many of you have not yet moved to Yosemite, some are stuck in Lion or Leopard, someone else is going back to El Capitan out of desperation ... but dear Apple, during WWDC16 that started on June 13, 2016, announced the new SIERRA operating system, another monster range ... mountainous !! *
* before hurting anyone's sensibilities I state that I am Apple addicted
First enough with this obsolete term IOS. From today it is called MacOS, version 10.12!
Let's see some news. 
The fulcrum of everything seems to have become SIRI, the same as it does on Iphones disgrace by car while you calmly try to make him understand that you don't want to call "Pina" but "Gina" and that you don't care about the weather in Marano But say Milan!
But this version of Siri will go further!
Now we can search for a file, a photo, open a program, connect to the cell phone, dictate ... Apple has promised everything and more! I can already see myself screaming at my macbook in the office!
Continuity
Our Mac will now see all nearby Apple devices (obviously only if updated to the latest version) and connect to the activities they were doing, continue them, stop them, etc.
We will be able to copy and paste between multiple devices. Copy a photo from Iphone and paste it on iMac and vice versa!
Open Sesame
Tired of typing your password on startup? If facial recognition, fingerprint, iris reading was not enough ... now you need theApple Watch to be able to unlock your mac without entering the password! So now you will also know why you bring a 500 euro Mickey Mouse watch! Who hasn't dreamed of it at least once? Textually in the presentation they say "just waste time entering text passwords!"
The "infinite" space
With Optimized Storage, if the disk is too full, we can use the cloud space to migrate the less used documents or we can even set up an automatic deletion system for little used documents.
Sliding images
Do you want to review your photos? Now you will have the possibility with one click to create amazing slideshows!
PIP
Who hasn't dreamed of seeing a movie while working? Well, now you can see it in a PIP, a small box on the screen (but doesn't Helium, vlc and others already?)
Apple Pay
Worried about shopping online? With a simple fingerprint reader, we will be able to memorize all our credit cards, passwords, etc., recalling them if necessary by inserting our fingertip.
On the nose, it seems to me the presentation of a lot of fried air to sell peripherals and have old devices thrown away. No vital updates. As already happened in the not too distant past and within a very few years, all Apple systems involved must align themselves with the new IOS to make the carousel spin and, as you know, Iphone 3-4 are already antique for some time, on 5 he will become one in this round and on the 6th he will wait for the upcoming successor release.
What will become of us… the audio!
Who knows, it's still early to speculate. What is certain is that the arms race will begin tonight! All music hardware and software manufacturers will give the Beta version to their technicians and try to align. Considering there are still updates to be made for Yosemite that's a nice prospect !!
Expect my usual article on incompatibilities, patches, tricks, regrets and unconditional returns!
But fear not, macOS will be available for download required from next autumn on the Mac App Store. If you don't produce software or hardware, enjoy the summer !!
