How do I remove my network from the recovery partition before sale? I'm about to put my old MBP up for sale, so I re-installed from the recovery partition after wiping the drive. But when I rebooted from the recovery partition to double-check I'd deleted everything, it connected to my wifi network. I've got two questions:


How do I remove my network credentials from the recovery partition?
What other personal information is it storing without my knowledge, and how do I wipe it?
The answer was indeed to reset the NVRAM by holding cmd-alt-p-r during boot. Cheers :)
