Create MacOS Sierra Install USB

Hi guys and welcome to 123 my IT’s video on how to create an MacOS Sierra Install USB.
Ok guys recently I did a video on how to download Mac OS Sierra and to see that video you can find it on the following link. How to download Mac OS Sierra.

That video shows you how to download this app and now the next step is to show you how to actually create a MacOS Sierra Install USB from this app. So the USB thumb drive has to be a minimum of 8 gigabytes in size for you install the OS X Sierra software on the USB and then you can do a fresh install of Mac OS Sierra from this use to any Mac.
Lets for example say you wanted to sell your old Mac or you had a problem with your Mac like you had a virus on there any need to do a fresh install. You can use this USB to format the Mac and install a fresh copy of OS X.

So the first step you will need to do is format the USB and you can do this by plugging your USB thumb drive and then go to go in the Apple menu and then go down to disk utilities.

Click on the USB that you want to format and make sure it’s set to Mac OS X extended journaled and keep it as untitled for now you can change this around but if you change this around you have to actually change the untitled part in the code there so let’s just leave it as untitled for now.

Make sure you have no important data on the USB because the next step will delete any data that was on the USB.
Once you have done this just click erase and then erase again. The USB will disappear and it will start to format the USB.

The next step is to download the install disc creator app you can get the install disc creator app from the 123myIT.com website, under downloads or simply click the link here.
Open up the install disc creator you will need to select the untitled USB from the drop-down menu. Make sure the OS X Sierra app is selected below then click create installer button. You may be prompted for a password this will be the administrator password type in the password and then click ok. This process can take about 5 to 10 minutes depending on the speed of your Mac.

Install Disk Creator

To do this same process with the terminal code copy the terminal code below then open up a terminal Window by going to finder and then type terminal and then hit return.

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

Simply right click and paste the command into the terminal window, press return again and you will be prompted for your administrator password type in your administrator password.

Terminal command MacOS Installer Disk

if successful you should see the terminal window start to erase the USB and copying installer files to the disc. Once this is done you should be able to then use the USB to do a clean install of any Mac.
I hope that helps guys ! πŸ™‚

How to Download macOS Sierra

How to Download macOS Sierra

This video and article will show you how to download MacOS Sierra, which can be used at a later date to install on any Apple Mac computer.

Why would you want to download a copy of OS X Sierra? When you have an offline copy that means you can then install it on any Mac, so let’s say you wanted to sell your Mac wipe all the data that was on the local hard drive before you sold it you can go through it and reinstall the operating system with macOS Sierra.
Another good thing about having the offline copy is you can actually install it on other Mac’s, also Apple tends to update this software once a year so if you don’t download a copy at some stage and you wanted to reinstall this particular version of macOS you won’t be able to.

So to download macOS Sierra it’s straightforward all you need to do is open Safari and then go to the Apple website. Or you can use this link as a quick link. http://www.apple.com/macos/sierra/

Apple Recall – AC Wall Plug Adapter

This video will show you how to identify an affected Apple AC Wall plug adapter. These adapters are being recalled by Apple because of a design fault where by the affected plug could shock some users.

This is a massive design fault by Apple a company that prides itself on great design. The adapter that comes with all iOS and Mac computers which allows you to change the power cord for a longer power cord or to change adapter type for different country’s.
If the plug gets damaged or breaks over time there is a chance that that you could take an electric shock.
Most people would assume when a plug is broken in this way that you would throw the plug out and by a new one, however improved design may actually stop being shocked even with a faulty plug.
And thus the Apple Recall has started.

So how do you tell If you have an Apple recall plug or not? Well here is Apples explanation below which I find that I had two read it a few times to make sense of it. πŸ™‚

Identifying your wall plug adapter
Compare your adapter to the images below. An affected wall plug adapter has 4 or 5 characters or no characters on the inside slot where it attaches to an Apple power adapter. Redesigned adapters have a 3-letter regional code in the slot (EUR, KOR, AUS, ARG or BRA).

Apple Recall

So can we have that in plain English please? Basically in these countrys Europe, Korea, Australia, Argentina and Brazil, If you check your AC adapter and it has 4 or 5 numbers on it or is blank then you can return it to an Apple store for an exchange.

Pretty straight forward? I don’t know why they didn’t just say that on their webpage.

OS X El Capitan Installer USB

This video will show you how to create an OS X El Capitan Installer USB.

Hi All,
We previously showed 123myIT users how to create an OS X Yosemite and Mavericks USB drive. And we have the video on how to create an OS X El Capitan installer USB. The process is very simular to the other OS X installer videos that we have done in the past. There is a few code changes so just be aware of that.
Again you will need a computer running Mac OS X and you will also need a 8GB or larger USB drive. In this video I didn’t take any chances and I use a 16GB USB drive, which are quite cheap to buy these days.

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/ElCapInstaller --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction

Copy and paste the code into a Terminal window and press enter, you will be prompted for a user name and password. This should be your Admin accounts user name and password. Remember to change the name of your USB device to ElCapInstaller if you miss this step the code will error out with something like incorrect syntax error. πŸ™‚

OS X El Capitan Installer USB

You should see the name of the USB change from whatever its called when you plug the USB in to Install OS X El Capitan. Once this has completed you should then be able to use the USB drive to do clean installs of OS X on almost any Mac hardware or computer. Its always helpful to keep a back up of OS X versions. Because if you ever want to go back a version or install OS X on a different Mac its good to have this backed up copy. Also Apple updates their OS X software once a year and then makes their old version unavailable. So to save yourself getting caught out this way the USB is a great step.

In the next video I will show you how to do a clean install this OS X El Capitan Installer that you have just created.

Cheers
