Q. What are Mac gestures?
A. Most new Apple products support multi-touch input. The Macbook’s built-in trackpad is a good example. You can also buy a multi-touch trackpad for Mac desktop computers. Multi-touch means you can control your computer with special gestures. A pinching or rotating gesture can zoom or rotate content. Four-finger swiping controls Expose and switches applications. There are lots of potential gestures. Of course, not every gesture will be useful to you. Try grabbing a free program like MagicPrefs from www.komando.com/news. It lets you customize any gesture to activate whichever action you what.
Q. I got an email from Facebook saying a new computer logged into my account. What does this mean?
A. Facebook implemented several new security features recently. One of those features is Login Notification. It notifies you by email whenever a login occurs. This is a great security feature. You can catch hackers logging in from unknown computers. If that happens, open your Facebook profile. Go to Account>>Account Settings. Then scroll down to the Account Security section and click the change link. Now, go to the Most Recent Activity section to see a list of account activity. You can remotely log out unauthorized users. Then change your account password to keep them from coming back.
