Apple releases security patches on a regular bases 2
and to find the details of the security issues related to the patches, 3
have a look at the Apple security updates page, 4
which you can see here in front of you. 5
If we scroll down, 6
we can see the latest issues and security updates. 7
Let's click on this one. 8
You can look up on mitre.org or the national vulnerability database 9
for more details as usual. 10
It will give you an idea of the criticality and if you want to install it, 11
but generally, you want to just install all security updates 12
unless you have some special reason why you don't want to. 13
OS X is able to download and install updates 14
for the operating system and the Apple App Store apps. 15
You can set this up for automatic updates 16
and this is done this way. 17
If you go here, 18
System Preferences, 19
App Store, 20
and here you can see the settings for automatic updates. 21
Here you have automatic updates. 22
That obviously needs to be checked to do the updates. 23
This will download them in the back ground 24
and you'll be notified when they're ready to be installed. 25
Click this if you want to install the app updates automatically. 26
Click this if you want to install the OS X operating system 27
updates automatically. 28
Here you can select to install the system data files 29
and security updates and obviously you definitely 30
want this one to be selected. 31
You can click here to check for the latest updates. 32
Here we can see an update is required, 33
and that provides the details of the update. 34
You can see here, it says security content of the update. 35
If we click here we can see the security content of this update, 36
which is there. 37
These are the latest options for Yosemite and El Capitan, 38
but in prior versions of OS X, 39
these settings won't look like this, 40
and I don't believe automatic downloading and installing 41
of updates is available in all prior versions. 42
And you may not be able to select for security updates as well 43
like you can here and with Microsoft. 44
If you only want to install security updates, 45
then you can of course deselect these 46
and just have it install the security updates. 47
Any other app that you have downloaded and installed 48
not from Apple or the App store is not updated 49
as part of these settings. 50
You'll need to update these manually 51
or you can try a tool called MacUpdate, 52
which is here. 53
This is an app that you download and install. 54
Think of it as a bit like another App Store 55
that has non-App Store apps in it. 56
It will detect what software is out of date 57
and allow you to download and install the latest version. 58
I found it to work okay. It does have a few bugs here and there, 59
and will show the same app twice sometimes. 60
I haven't found a better alternative though. 61
And it is pretty good at keeping the rest of your apps 62
up to date with the latest versions. 63
Let me play this quick video so you can get a good idea. 64
[Video Starts] 65

If you are, as I'm sure you probably are, as you're doing this course, 93
going to install extra power tools onto OS X 94
because Apple hasn't included them, 95
then I recommend you install Brew. 96
Brew is the missing package manager for OS X. 97
If you use this it means you can also update 98
and upgrade those packages via the Brew tool. 99
If you copy and paste this 100
into your terminal, 101
there you go, it's installed. 102
You will need admin privileges in order to install it though. 103
If type brew help, 104
that will help you on how to use it or man brew. 105
I'll show you a quick few commands. 106
This will search for the package nmap. 107
You can do, 108
this will install nmap. 109
So that's nmap installed. 110
There we go, and nmap's there, how quick and easy was that? 111
Brew update, 112
this checks if it's up to date. 113
You can find out if any of the packages are outdated. 114
You can upgrade any package that needs upgrading, 115
or you can specify a particular package that needs upgrading. 116
You can see nmap is up-to-date. 117
And this will show you the packages that you have installed. 118
You can see that we've also got open SSL 119
installed as well because that came with nmap. 120
So there you go, that's Brew.
