Hey guys, I have a MacBook Pro late 2011 edition which is pretty slow compared to the MacBook Pro I bought last year. So I have been thinking about giving my old laptop some new life. But I will give you the steps on how I upgraded my laptop in another blog.

But first, we need a Bootable Mac OS Sierra so that when I change the hard disk to another SSD I will have an Operating System to work on.

Even if you are not planning on upgrading your hard disk, it’s a good idea to have a backup of your OS.

Things you need

– USB Flash Drive with at least 8 GB space.

I recommend formatting your flash drive. Here’s how you do it

  1. Go to Finder > Applications > Utilities > Disk Utility
  2. Select your flash drive from the External Column and click Erase from the top menu
  3. I recommend renaming it to something more clear that its an Installer flash drive. I am naming mine ‘macOSInstaller‘. Be sure to use one word without spaces.
  4. Choose Mac OS Extended (Journaled) as the format.
  5. Leave the scheme as ‘Master Boot Record’
  6. click Erase

– Download MacOS Sierra

  1. Go to Mac App Store and download MacOS Sierra
  2. This will be saved in your Finder > Applications folder.

Now, all we want is to put this file into the flash drive so that the laptop boots up with this installed file.

– Open Terminal and paste the following command

  1. Paste the following command

sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MACINSTALL --applicationpath /Applications/Install\ macOS\ High\ Sierra.app --nointeraction &&say Done

2.  Enter your mac password

That’s it 🙂

Now in the next blog, I will go through how I upgraded my late 2011 MacBook Pro.
