How to Clean Out Cookies on a Mac
Websites often write small, benign, files to a computer in order to remember information about the person visiting it. This file is called a cookie, and websites utilize this to remember anything from shopping carts on shopping websites to login data for email. Cookies pose no threat to a computer's safety, but the files take up space and can be accessed by people using the computer. Cookies should be cleared out on public or shared computers or to retrieve used hard drive space.
