What is Mac OS Sierra & How to install it?

The highly-anticipated OS X 10.12 was officially revealed with a new name – Mac OS Sierra, at the Worldwide Developers Conference (WWDC) in June 2016. As we experienced in the move from OS X 10.10 Yosemite to 10.11 El Capitan, Sierra isn’t just a compilation of bug fixes and performance updates-it’s a full-fledged follow-up to last year’s update.


Is your Mac compatible?


If you have the following model of Mac, you can download and install Mac OS Sierra:

Mac Pro (mid 2010 or newer)

iMac (late 2009 or newer)

Mac mini (mid 2010 or newer)

MacBook Pro (mid 2010 or newer)

MacBook (late 2009 or newer)

MacBook Air (late 2010 or newer)

If your Mac is older than any of the models listed above. You can’t install Mac OS Sierra.

Even if you’re Mac is on the compatibility list, that doesn’t mean you can take advantage of all of the new features in Sierra. There are other things to consider. You’ll need a newer model Mac and a compatible iPhone or Apple Watch to use such things as Handoff, Auto Unlock, Siri, Apple Pay on the Web, Apple’s Continuity features, and more.

In general, in order to use all of the new features in macOS Sierra, you should have the following Mac:

Mac Pro (late 2012 or newer)

iMac (late 2012 or newer)

Mac mini (late 2012 or newer)

MacBook Pro (mid-2012 or newer)

MacBook (Early 2015 or newer)

MacBook Air (mid 2012 or newer)

You should also have an iPhone 6 or newer running iOS 10. If you hope to use Auto Unlock, you also need a Mac that is from 2013 or newer and an Apple Watch running watchOS.


Not To Forget

1. No matter what system software you update, you always should backup first. Don’t skip making a complete and thorough backup of your Mac before installing MacOS Sierra.

2. Connect an external hard drive to your Mac. Choose a new hard drive, or one that you don’t mind erasing.

3. An alert may appear asking if you want to use the drive to backup your Mac. If so, Use as Backup Disk.

4. If not open System Preferences > Tim Machine and click Select Backup Disk. Choose the external drive.

5. Switch Time Machine to On.

6. A progress bar will appear in the Time Machine system preference pane. Wait for the Time Machine backup to complete before continuing with the Mac OS Sierra installation.


Things you must try this time :


1. Siri


MAc Os siri


Siri is a built-in, voice-controlled personal assistant available for Apple users. The idea is that you talk to her as you would a friend and she aims to help you get things done, whether that be making a dinner reservation or sending a message.

Siri is designed to offer you a seamless way of interacting with your iPhone iPad, iPod Touch or Apple Watch by you speaking to her and her speaking back to you to find or do what you need. You can ask her questions, tell her to show you something or issue her with commands for her to execute on your behalf, hands-free.

Siri has access to every other built-in application on your Apple device – Mail, Contacts, Messages, Maps, Safari, etc – and will call upon those apps to present data or search through their databases whenever she needs to. Ultimately, Siri does all the leg work for you. It means you can carry out a single task by just saying “Hey Siri” or double tapping the Home button, rather than open multiple apps or spend time writing messages or finding contacts.


2. Apple Pay


Apple Ipay


In Mac OS Sierra, you can use Apple Pay from the Safari web browser (sorry, Chrome and Firefox users) to buy from online vendors with a quick tap, as long as you have an iPhone or iPad with Touch ID handy. Right now, supported merchants include Time Inc., Lululemon and Warby Parker, with more sure to pile on to make it easy for customers to buy their wares.


3. Apple watch

Apple watch


The Apple Watch and Mac OS Sierra connect to let you unlock your Mac automatically. the Auto Unlock feature connects your Mac and your Watch so that it knows when you are getting ready to work and it will automatically unlock your computer.

This only works on if your Mac is a 2013 model or newer and you will need to install watchOS 3.0 on your Apple Watch, Apple Watch Series 1 or Apple Watch Series 2.


4. Photos-

Photos for Mac gets new features, too. A new Memories tab automatically creates slideshows based on events, places, or people. There’s also support for extensions for Photos that will allow for editing of Live Photos. When you make an edit, it will apply to the whole Live Photo, not just the one sequence you edited.

Some of the other neat features:

Apple File System, a new file system not only for macOS but also for iOS, tvOS, and watchOS. (Launches in 2017)

enhanced Messages.

support for third-party app integration with the Contacts app.
Apple Music improvements.

Download Mac OS Sierra for a clean Install

Step 1: To start the clean install, begin with step 1 above (under the upgrade section). However, once you have downloaded the operating system, it will try to install itself. So as soon as Mac OS Sierra has finished downloading, quit the install.

Step 2: Next, you are going to use the installer that downloaded with the OS to make a USB drive. This will allow you to perform a clean install of Mac OS Sierra on your Mac.

To do this, you need a USB flash drive that is formatted and not titled. Now follow the below steps:

Launch Terminal: Finder > Applications > Utilities > Terminal
Next, enter: sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia – volume /Volumes/Untitled –applicationpath/Applications/Install\ macOS\ Sierra.app –nointeraction

Tap the enter key

Now Terminal will require you to enter an admin password. You should enter the one you use to login. When done, you will see that Terminal has erased your drive. It is at this point that Terminal will copy the installer to your disk. Be patient; it could take a few minutes to complete. However, when ready, it will let you know.
You can now end Terminal, and your USB drive will have the bootable Mac OS Sierra installer on it ready for use.


Installing Mac OS Sierra from a flash drive

Now that you have a bootable flash drive with everything you need, it is time to install Mac OS Sierra.

Step 1: Plug the flash drive into your Mac.

Step 2: Next, restart your Mac and at the same time, hold down the Option key or Cmd+R.

Step 3: When your Mac restarts, you will see a list of bootable devices. Using the arrow keys, chose the USB flash drive with the Mac OS Sierra installer on it and press Enter.

Step 4: Now select Disk Utility. Then in the top left bar, you need to select MacintoshHD; this is your Mac’s main D drive.

Step 5: Select the Erase tab; you will find it near the first aid button at the very top.

Step 6: Next, you need to select Mac OS X Extended Journaled. You will find this in the center of the screen in the Format drop-down list.

Step 7: This next step will remove all of your data from your primary drive. However, it is necessary to complete the clean install, so click Erase and wait for the formatting to complete.

Step 8: When the formatting has been completed, exit the Disk Utility and select Install macOS. You will find this option in the menu.

Step 9: Now to install Mac OS Sierra onto your primary drive, select it, and the process of installing the latest Mac OS from Apple will begin.

Again, installing a new OS, especially a clean install, is a matter of patience. So once the OS starts to install, follow the on-screen instructions and enjoy your clean install.

  1. I’ll pass thanks.
    I’m still having nightmares over the “Free” Yosemite upgrade that didn’t fix any of the known bugs in the Snow Leopard OS and rather just added a new, bland and unimpressive layer onto of a great OS that was Snow Leopard.
    Was a major headache to roll back despite Time Capsule claiming its supposed to be a simple process.

    No thanks, never again!
