Restore old PowerBook G4 before/for Apple Recycle Program.
I have an old PowerBook G4 I need to send to Apple for its recycling program. But it's still got all of my stuff inside it I've just transferred it to my new MacBook. I need to wipe everything out before I can send it like erase the disk and restore its orginal settings. I know I should own the Lion dvd to be able to do this BUT thing is I have NO cd/dvd in the box. There's everything else as I purchased my MacBook in an Apple Store BUT there is NO such thing as a cd/dvd. Can I do the process in some other way or am I forced to bring the old computer to an Apple Store? Thank you.
MacBook Pro, Mac OS X (10.7.2), 17''
