Overview

The Mac OS sierra differed from its successors with revolutionary features that hauled the operating system into drastic movement in the market. The overall look and appeal of the operating system under usage seemed to be the reason why the end-users loved the operating system upon its release. Here are some features you must not miss if you are a Mac OS sierra user.

1. The Auto Unlock feature

This tech feature allows you to pair your favourite apple device with your MacBook or a Macintosh computer. Once you have paired through Bluetooth or Wi-Fi your favourite apple device say the apple watch, when the watch is in close proximity with the device it automatically unlocks without you entering the passcode. This is a feature that will be really useful for hardworking professionals who are on a constant run. Well, the practicality with the feature. Now for this feature to work you need a Mac that is 2013 or older. There is a time of flight feature that is imbibed within the feature to prevent attacks from relay usage so that your device is also not misused.

2. Night Shift

This is the same feature that is present in the previous generation of the Mac OS series but with a small tweak. Before you could not set the time at which the night mode must activate, but with this Sierra OS, you can set the preferred time at which you want to toggle the might mode. This can be set by going to the Preferences tab in the settings tool. This feature was very much useful for people who work round the clock on their systems.

3. Universal Clipboard

The universal clipboard is the counterpart with the auto-unlock feature. If you are Mac system is paired along with your iOS 10 devices, then you can share the links that you have copied or cut and paste across the devices that are paired along with your devices. This is also helpful in sharing rich content like photos, videos as well across the platforms. The universal clipboard feature was well appreciated by the end-users due to the integration of the devices across the various apple devices.

4. Picture in picture feature

Now the Mac users can use various pictures within several pictures. This will help the user to access more than one picture at a time and is definitely a boon for the people who are involved in editing photos. You can also play videos in the application while there are several background applications that are running behind. There are a lot of other additional adaptabilities as well that enables the picture in picture feature to be a wonderful hit among the users.

5. Gatekeeper

The Mac OS Sierra has a major upgrade in the Gatekeeper user interface by adding two new security features that make the usage of your system much safer and save you from data theft. There is an Anywhere option in the system preference tab that allows the user to execute software programs without getting permission to run the same.

The Code-sign disk feature would help the developer to add a signature of his own so that it cannot be tampered by an attacker. If the attacker tries to infect the software with his malicious code, he would have to require to re-write his files under a new file disk that won’t be passed by the Gatekeeper.
