How to Restore Your System

What is system restore?

System restore helps you to restore your system’s files to a previous known good configuration without affecting your personal files such as photos, videos, or emails. It’s a way to undo the changes to your system. Sometimes installation of a program and a driver may cause unexpected change in the system, usually uninstallation of the driver corrects the problem but if the problem persists you can solve it by restoring your system.

Finding your Mac OS X version and build number

10 Tips For Your Facebook Privacy

1. Organize Friends in Lists

What do you do when your boss, mother-in-law, or a casual web acquaintance sends you a friend request on Facebook? Use Friend Lists. Friend Lists are the foundation of your Facebook privacy settings. Select Friends from the top menu, and use the Create link to create friend lists like Co-workers, Family, College Friends, etc. Your friends can’t see your lists, so you can name them whatever you like.

Tip: On your left sidebar, all your friend lists may not show up by default. Click More to see all of them, and drag and drop those you want above the separator.
