Cookies are small files that Web developers use to track your path through their website, and to determine which page to display to you when visiting their site. For example, by setting a cookie, a weather website displays your local forecast or an online store displays items that you recently showed an interest in buying. Cookies are generally harmless; however, there are times when you may wish to erase the cookies on your MacBook for privacy reasons. For example, when you are using a work MacBook for personal use, or you wish to start fresh with new browser settings.
