It started with mavericks–a popular big wave surfing destination–and is now heading back on land to the “Yosemite” National Park. Well, if you are running Yosemite OS on your Mac there’s a new security update available for you. The fruit company and labeling this one as important so it’s best you update when you can and don’t leave it until later. There are a few different ways you can go about installing Security Update 2015-003 1.0 in OS X. Here’s how to do that.

REQUIREMENTS

1. You should first take a backup using Time Machine before going ahead if there’s important data you don’t want to lose. You shouldn’t lose the data by updating the software unless something goes wrong, but it’s better to be safe than sorry.

2. Those people who have their own preferred method for backing up the data can do that before starting instead. As long as you store the data so it’s safe.
