How to erase data from Snow Leopard without startup disk?
I have an old Macbook running 10.6.8 - I believe it is a 13-inch from late 2006. I want to erase my data in order to recycle it. I can't find a way to do so without the startup disks - there's no recovery mode on this version, and I can't upgrade to Yosemite because I don't have enough memory. I'd rather not spend $20-30 on purchasing Snow Leopard disks since I just want to get rid of the computer. Is there any way to wipe the hard drive? Thank you!
MacBook, Mac OS X (10.6.8)
