so i guess i got to get another copy of Lion then? does apple still sell Lion on a stick (usb)?
Yes they do.
He might be thinking that using a USB stick would allow him to securely erase his hard drive before re-installing the OS. He would be incorrect. For some unfathomable reason, Disk Utility wont allow you to do this when using 10.7 and an SSD drive. That means when you sell a computer, you cant securely delete your personal files, and have to hope that they buyer doesn't try to use a disk recovery utility to access your personal data. Simply overwriting the disk with a fresh install of the OS doesn't make them go away. Very poor security. Apple needs to address this.
