Everyone should be running “Software Update” on their Macs. It provides critical updates to OS X. However, sometimes it isn’t handy to get your updates where you are. For example you might not have a very fast internet connection at home, but you have a T1 at work. That is where Apple’s website comes in handy. No matter where you are, you can head over to their website, and you can download any update that you need. To make sure you have the right one, click on the name of the update to validate that it is for your computer.
