erasing hard drive
Help! I am preparing to recycle my MacBook from 2002 (!) and I am trying to erase the hard drive. I have backed up everything on an external drive, signed out of iCloud and iTunes. I am in the Disk Utility and when I click on the hard drive it won't give me an option to erase.....Any easier way to do this? Do I have to erase the free space first? The MacBook is soooo old, it takes DAYS to back up and erase free space. Not very tech savvy so any help is appreciated!
Thanks!
