Why can't I Erase system drive with Security Options?
I'm getting ready to return my MacBook Pro and I want to wipe the system drive. I've booted in recovery using cmd+r. I opened Disk Utility, selected the SSD drive and the Erase tab. The Security Options button is grayed out. How do I securely erase the drive?
MacBook Pro (Retina, 15-inch, Late 2013), OS X Mavericks (10.9.4)
