If you want to securely erase the internal drive of a MacBook before you sell or trash it, you’ll have to (a) boot Disk Utility from a Mac OS X Installation DVD for versions up to and including 10.6 or (b) boot the utility from the OS X Recovery Partition. Backup whatever data you want to keep, and choose one of the following options. Securely erasing drives before disposal makes sense and it’s easy to do using Disk Utility's Erase feature on a Mac.
