Tip: Ever lose your cursor? We all do at some point or another. You can't seem to find that little arrow anywhere on the screen. In OS X El Capitan (10.11), if you wiggle your mouse or brush your finger back and forth on the trackpad, your cursor will wiggle and become larger for a moment allowing you to find it on the screen. Never lose your cursor again!

Tip: Did you know most of what you do on a Mac can be undone? If you ever get that sinking feeling while working on your Mac, go up to the Edit menu and choose Undo. It's the very first item on the menu. Many times you may be able to undo more than once, allowing you to get back onto solid ground again. There is also a keyboard shortcut for Undo: Command Z.
