It is totally okay to remove cookies from your Mac. In short, cookies are files on your Mac to keep the information of what you've done on a website. You remember that sometimes when you return to a website, the site shows you the items you checked out last time or it keeps your username? That's because of the cookies.
When you visit a site again, your browser (Safari, Chrome, FireFox, etc.) sends the cookie to the website so that the site recognizes you and what you did on the last visit.
