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/

I will do a video of how to install macOS Sierra on USB too shortly, but basically if you wanted to install this on the USB lets say you had some problem with your Mac any wanted to do a fresh install, maybe it got a virus or something like that.

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. 🙂

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. 🙂

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
