Help erasing Hard Drive; normal process does not work.
Can anyone help me figure out how to erase my hard drive for an upcoming sale. I have a 13" MacBook Pro running 10.6.8. I have tried using the install dvd and holding c or option key but nothing seems to work. I have accessed disk utility and clicked the HD but the only option available is erase free space. The other button will not highlight nor will the drop down buttons above (journaled, etc). Thanks.
MacBook Pro, Mac OS X (10.6.8)
