Apple releases security patches on a regular bases
and to find the details of the security issues related to the patches,
have a look at the Apple security updates page,
which you can see here in front of you.
If we scroll down,
we can see the latest issues and security updates.
Let's click on this one.
You can look up on mitre.org or the national vulnerability database
for more details as usual.
It will give you an idea of the criticality and if you want to install it,
but generally, you want to just install all security updates
unless you have some special reason why you don't want to.
OS X is able to download and install updates
for the operating system and the Apple App Store apps.
You can set this up for automatic updates
and this is done this way.
If you go here,
System Preferences,
App Store,
and here you can see the settings for automatic updates.
Here you have automatic updates.
That obviously needs to be checked to do the updates.
This will download them in the back ground
and you'll be notified when they're ready to be installed.
Click this if you want to install the app updates automatically.
Click this if you want to install the OS X operating system
updates automatically.
Here you can select to install the system data files
and security updates and obviously you definitely
want this one to be selected.
You can click here to check for the latest updates.
Here we can see an update is required,
and that provides the details of the update.
You can see here, it says security content of the update.
If we click here we can see the security content of this update,
which is there.
These are the latest options for Yosemite and El Capitan,
but in prior versions of OS X,
these settings won't look like this,
and I don't believe automatic downloading and installing
of updates is available in all prior versions.
And you may not be able to select for security updates as well
like you can here and with Microsoft.
If you only want to install security updates,
then you can of course deselect these
and just have it install the security updates.
Any other app that you have downloaded and installed
not from Apple or the App store is not updated
as part of these settings.
You'll need to update these manually
or you can try a tool called MacUpdate,
which is here.
This is an app that you download and install.
Think of it as a bit like another App Store
that has non-App Store apps in it.
It will detect what software is out of date
and allow you to download and install the latest version.
I found it to work okay. It does have a few bugs here and there,
and will show the same app twice sometimes.
I haven't found a better alternative though.
And it is pretty good at keeping the rest of your apps
up to date with the latest versions.
Let me play this quick video so you can get a good idea.

If you are, as I'm sure you probably are, as you're doing this course,
going to install extra power tools onto OS X
because Apple hasn't included them,
then I recommend you install Brew.
Brew is the missing package manager for OS X.
If you use this it means you can also update
and upgrade those packages via the Brew tool.
If you copy and paste this
into your terminal,
there you go, it's installed.
You will need admin privileges in order to install it though.
If type brew help,
that will help you on how to use it or man brew.
I'll show you a quick few commands.
This will search for the package nmap.
You can do,
this will install nmap.
So that's nmap installed.
There we go, and nmap's there, how quick and easy was that?
Brew update,
this checks if it's up to date.
You can find out if any of the packages are outdated.
You can upgrade any package that needs upgrading,
or you can specify a particular package that needs upgrading.
You can see nmap is up-to-date.
And this will show you the packages that you have installed.
You can see that we've also got open SSL
installed as well because that came with nmap.
So there you go, that's Brew.
