You have the documentation for your Mac or other Apple product somewhere. Perhaps its in the box, or stashed in a desk drawer. The day may come when you need to reference the manual for your Apple product. Forget searching.. go right to Apple and download it.
Here is how to do it: Go to www.apple.com/support/manuals Browse through the manuals, or click inside the search box and type in exactly what you are looking for. When you find the manual you want, click on it, and it will download in PDF format for quick and easy viewing or printing.
