I have an old Mac with OS X 10.6 Snow Leopard operating system. Now I am planning to sell it on eBay.com to get money to buy a new MacBook Pro. However, before delivering it to the buyer, I want to make sure all the existing data and history data on the hard drive has been wiped off. I delete all my documents and empty the trash bin, but the deleted documents and other more files still can be recovered by a data recovery program on my Mac. Nowadays, data recovery programs are very popular. So people can recover my deleted documents, intentionally or unintentionally. How can I do to permanently erase hard drive data under Mac OS X 10.6 Snow Leopard?
