Updating the software on your computer is important.
Updates can apply to little things that improve functionality or major
things that improve security. We recommend turning Software Update to automatically
check
and
notify you in order to always be current.
Please Note: when
running Software Update make sure that your laptop is plugged in and not
running off of battery power. Also, set your
energy settings
preferences to "Never" during this time.
To run/turn Software Update on, follow these steps:
1. Click on the Apple Menu and select "System
Preferences". A new window will open up with all of your system preferences.

2. Find the icon labeled "Software Update" and
double click on it.

3. A new window will open up. These are your
Software Update preferences. Check the box next to "Automatically check
for Updates" and set the time.

4. If you click "Check Now", it will check for
any updates. If there are any that are not installed you will be given
the following screen.
5. Check the box next to the updates you wish to install and click install.
You will be prompted for your password to install the updates. You may
or may not be asked to restart your computer after the updates are installed.
Apple has its own article on this which can be found at http://www.apple.com/macosx/upgrade/softwareupdates.html
